SAE Aero Design Rules | |
Version 2024.0 | |
i | |
Forward | |
Welcome to SAE Aero Design 2024! This competition has been affording students with | |
relevant aircraft design challenges and real-world engineering experience since 1986. Technical | |
competition is a hallmark of the aerospace industry. This competition introduces students to the | |
concepts of design, manufacture, and performance through an industry-like series of events. | |
During the SAE Aero Design competition students will demonstrate and compete their | |
technical acumen to industry-leading judges in three categories: written, oral, and aircraft | |
performance. Students will experience design through development of an aircraft to a rules-set | |
technical performance specification. Manufacturing follows the design phase; students will | |
produce their design in preparation for a two-day fly-off against their peers from other | |
universities from across the world. Students will experience strategic elements of design thinking | |
as accurate performance prediction influences all phases of the competition. | |
Competitors will enter a new aircraft for one of three classes: Regular, Advanced, and | |
Micro Classes. This year’s competition introduces a new rules-set to the Micro Class. | |
Micro Class: This competition challenges students to develop a small, light-weight aircraft. | |
In the continued spirit of wildfire management, this competition introduces large-volume fluid | |
management concepts to aircraft design. | |
Regular Class: As the competition’s legacy aircraft class, Regular Class focuses on | |
engineering fundamentals for constrained take-off under limited power available. The large | |
airframe size requirements test students’ structural design optimization skills to achieve | |
maximum payload weight performance. | |
Advanced Class: Today’s world is prone to environmental tragedy. Students participate in | |
a campaign against an unpredictable and evolving wildfire disaster in both airborne and ground | |
fire-crew resupply. This class challenges students to balance diverse and conflicting requirements | |
and introduces concepts related to autonomy and telemetry. | |
In addition to the new rules-set for Micro Class, this year the competition’s technical | |
presentation is changing focus from the previous design review to a Flight Demonstration | |
Readiness Review. These reviews help students assess their team’s preparedness for competition | |
flight demonstration. Engineers in industry are often required to conduct similar reviews for key | |
stakeholders prior to conducting expensive test programs. | |
Please, read and apply the rules-sets carefully and remain informed on rules clarifications | |
through our Frequently Asked Questions page and submit questions through the competition | |
forum. Finally, the Rules Committee closely reviews feedback each year to bring greater | |
educational value and a better experience, so please participate in the survey after this season. | |
Our team is excited for the 2024 competition. Our ardent desire is to augment the | |
university education experience through practical application of technical concepts. Please apply | |
as soon as possible to secure your team’s registration. If your team is waitlisted, please, continue | |
with your preparations as we are often able to accommodate prepared waitlisted teams as | |
competition deadlines approach. Good Luck! | |

1 COMPETITION REQUIREMENTS | |
INTRODUCTION | |
Official Announcements and Competition Information | |
The SAE Aero Design competition provides undergraduate and graduate engineering | |
students with a real-world design challenge. These rules are developed by industry | |
professionals with a focus on educational value and hands-on experience. These rules | |
compress a typical aircraft development program into one academic year. This competition | |
exposes participants to conceptual design, manufacturing, system integration/test, and | |
verification through demonstration. | |
SAE Aero Design features three competition classes—Regular, Advanced, and Micro. | |
1. Regular Class is an all-electric class designed to develop a fundamental | |
understanding of aircraft design. | |
2. Advanced Class is an all-electric class designed to inspire students to take a systems | |
approach to problem solving, while encouraging them to explore autonomous flight. | |
3. Micro Class is an all-electric class designed to encourage students to explore | |
multiple design paths through trade-studies to uncover the most effective and | |
efficient approach to solving real industry challenges. | |

SAE Aero Design 2024 – Page: 11 | |
RINGERS PROHIBITED | |
To maintain the integrity of the competition, the Faculty Advisor(s) must prohibit ringers. A | |
ringer is someone with exceptional skills related to the competition (e.g., a professional | |
model builder) that cannot be a legal member of the team but helps the team win points. | |
DESIGN AND FABRICATION | |
The aircraft shall be designed and built by the SAE International student members without | |
direct involvement from professional engineers, radio control model experts, pilots, | |
machinists, or related professionals. The students may use any literature or knowledge | |
related to R/C aircraft design and construction and information from professionals or from | |
professors, as long as the information is given as a discussion of alternatives with pros and | |
cons and is acknowledged in the references in the design report. Professionals may not make | |
design decisions, nor contribute to the drawings, the report, or the construction of the | |
aircraft. The Faculty Advisor shall sign the Statement of Compliance given in the Appendix. | |
ORIGINAL DESIGN | |
Any aircraft presented for competition shall be an original design conceived by student team | |
members. Photographic scaling of an existing model aircraft design is prohibited. Use of | |
major components such as wings, fuselage, or empennage of existing model aircraft kits is | |
prohibited. Use of standard model aircraft hardware such as motor mounts, control horns, | |
and landing gear is allowed. | |
OFFICIAL LANGUAGES | |
The official language of SAE Aero Design series is English. Document submissions, | |
presentations and discussions in English are required at all US competitions in the series. | |
Team members, judges and officials at Non-U.S. competition events may use their respective | |
national languages for document submissions, presentations and discussions if all parties | |
involved agree to the use of that language. | |
UNIQUE DESIGNS | |
Universities may enter more than one team in each SAE Aero Design competition, but each | |
entry must be a unique design, significantly different from each other. If the aircraft are not | |
significantly different in the opinion of the Rules Committee and Organizer, then the | |
university will be considered to have only a single entry and only one of the teams and its | |
aircraft will be allowed to participate in the competition. For example, two aircraft with | |
identical wings and fuselages but different empennages would not be considered | |
significantly different. For guidance regarding this topic, please submit a rules question at | |
www.saeaerodesign.com. | |
AIRCRAFT CLASSIFICATION/DUPLICATE AIRCRAFT | |
One Team Entry per Class | |
A university is limited to registering one team per class (Regular, Advanced, Micro). | |
Backup Aircraft | |
Any back-up aircraft must complete inspection before flying. | |
SAE Aero Design 2024 – Page: 12 | |
AIRFRAME ELIGIBILITY | |
Airframes will only be allowed to compete during a single academic year. An airframe may | |
be entered in both SAE Aero Design East and SAE Aero Design West during the same | |
academic year, but that same airframe may not be used in either competition during the | |
following year. Entering the same airframe in SAE Aero Design West one year and SAE Aero | |
Design East the next year is not allowed. | |
An airframe is considered “entered to competition” during an academic year once design | |
documentation is submitted. If the airframe does not fly at competition during that same | |
academic year, the airframe is not eligible for competition during future academic years. | |
The airframe shall be designed within eleven (11) months of competition and constructed | |
within nine (9) months of competition. The airframe includes the fuselage, wings, and tail. | |
REGISTRATION INFORMATION, DEADLINES AND WAITLIST | |
Teams intending to participate in the SAE Aero Design competitions must register online per | |
the registration schedule in Table 1.1. By registering for any university program, the | |
registered University assumes liability of the student project. | |

Event | |
Start (Open) | |
End (Closed) | |
Registration Window September 18, 2023 10:00 AM EDT November 20, 2023 11:59 PM EST | |
The registration fee is non-refundable and failure to meet these deadlines will be considered | |
a failure to qualify for the competition. Separate entry fees are required for the events. | |
Team/Class/University Policy | |
A university or college can only have one team registered per class. The registration | |
fees must be paid within 48 hours of registration to be eligible. | |
Individual Registration Requirements – ACTION REQUIRED | |
A team member must be enrolled as degree seeking undergraduate or graduate | |
student at the college or university of the team with which they are participating. Team | |
members who have graduated during the seven (7) months prior to the competition | |
remain eligible to participate. | |
All participating team members and Faculty Advisors must ensure they are individually | |
affiliated to their respective college or university on the SAE International website | |
(www.sae.org) Team Profile page. | |
If you are not an SAE International member, go to www.sae.org and select the | |
“Membership” link. Students will select “Student Membership” and answer the series | |
of questions. All student participants must be members of one of the organizations | |
listed in Section 1.3 to participate. | |
Faculty members who wish to become SAE International members will select | |
“Professional Membership”. This is not mandatory for Faculty Advisors. | |
All student participants, both domestic and international, and Faculty Advisors must | |
affiliate themselves to the appropriate team(s) online prior to competition. | |
SAE Aero Design 2024 – Page: 13 | |
The “Add New Member” button allows individuals to access this page and include the | |
necessary credentials. If the individual is already affiliated to the team, simply select | |
the Edit button next to the name. This must be done separately for each event your | |
team has entered. | |
Each team member may participate for only one team. If the university or college is | |
entering multiple classes, team members must choose only one team to affiliate and | |
participate with in the competition. For example, students cannot compete as part of | |
a Micro class team and an Advanced class team. | |
Pre-Registration Information | |
SAE will utilize a pre-registration process. Teams who placed top 3 overall in their class | |
during the previous competition will be awarded the opportunity to register up to one | |
week prior to general registration. Pre-registration is restricted to the relative class and | |
event (East or West) of the previous year. For example, if you were in the top 3 in your | |
class at SAE Aero Design East in 2023, you can pre-register for that same class at the SAE | |
Aero Design East 2024 event. Starting on September 11th 10:00 AM ET, top placing | |
teams from the 2023 season will have early access to register. | |
Any team that placed top 3 overall at both events will have to choose one event for preregistration. The team can then register for a second competition after the one-event | |
registration restriction is lifted on October 2nd. | |
Here is the list of 2024 pre-registration eligible teams. | |
**NOTE: When your team is registering, only the student or Faculty Advisor | |
completing the registration needs to be linked to the college or university. All other | |
students and faculty can affiliate after registration has been completed; however, this | |
must be completed no later than two (2) weeks before the competition start date. | |
WAITLIST | |
Once an event reaches the venue’s capacity, all remaining registered team(s) will be placed | |
on a waitlist. The waitlist is capped at sixty (60) spaces per event and closes on the same day | |
registration closes. Once a team withdraws from an event, an SAE International staff | |
member will inform your team by email (the individual who registered the team to the | |
waitlist) that a competition spot has opened. You will have 24 hours to accept or reject the | |
position and an additional 24 hours to complete registration payment. Waitlisted teams shall | |
submit all documents by the deadlines to be considered serious participants and any team | |
that does not submit all documents will be removed from the waitlist. | |
POLICY DEADLINE | |
Failure to meet deadlines | |
Teams registering for SAE Aero Design are required to submit several documents | |
prior to the competition including a Design Report and Technical Data Sheet. When | |
these documents are not submitted, judges cannot accurately assess the team. | |
Additionally, teams that do not submit the required documents typically do not come | |
to the competition. Teams that do not notify us they are withdrawing create the | |
following problems: | |
SAE Aero Design 2024 – Page: 14 | |
• They are included in the static event schedules and judging time is wasted. | |
• Their unused registration slot cannot be offered to a team on the waitlist. Additionally, | |
failure to submit the required documents is a violation of the rules. | |
Late Submission Penalty | |
Late submission or failure to submit the Design Report, Technical Data Sheet(s), and | |
Drawings by the deadline will be penalized five (5) points per day. If your required | |
documents are received more than five (5) days late, the documents will be classified | |
as “Not Submitted” and your team will not be allowed to participate. Additionally, the | |
automatic withdrawal policy will be in effect. | |
Automatic Withdrawal Policy | |
Failure to submit the required Design Report, Technical Data Sheet(s), and Drawings | |
within five (5) days of the deadline constitutes an automatic withdrawal of your team. | |
Your team will be notified before or on the 4th day of no submission that we have not | |
received your documents and after the 5th day your team’s registration will be | |
canceled. No refunds will be given. | |

FACULTY ADVISOR | |
Each team is expected to have a Faculty Advisor appointed by the college or university. The | |
Faculty Advisor is expected to accompany the team to competition and will be considered by | |
competition officials to be the official university representative. Faculty Advisors may advise | |
their teams on general engineering and engineering project management but may not | |
design any part of the vehicle nor directly participate in the development of any | |
documentation or presentation. Additionally, Faculty Advisors may neither fabricate nor | |
assemble any components nor assist in the preparation, maintenance, or testing of the | |
vehicle. In brief, Faculty Advisors may not design, build, or repair any part of the aircraft. | |
Faculty Advisors may not participate in flight operations during competition weekend except | |
as noted. | |
QUESTIONS, COMPLAINTS AND APPEALS | |
Questions | |
Any questions or comments about the rules should be brought to the attention of the | |
Rules Committee by submitting a question at https://www.saeaerodesign.com. | |
General information about hotels and other attractions in the area, as well as a | |
schedule of events, will be posted on the SAE International website: | |
https://www.sae.org/attend/student-events/ | |
Complaints | |
Competition officials will be available to listen to complaints regarding errors in | |
scoring, interpretation, or application of the rules during the competition. | |
SAE Aero Design 2024 – Page: 15 | |
Competition officials will not be available to listen to complaints regarding the nature, | |
validity, or efficacy of the rules themselves at the competition. In other words, the | |
Organizer will not change the rules-set at the field, unless competition safety requires | |
updates. | |
Appeal / Preliminary Review | |
A team can only appeal issues related to scoring, judging, venue policies, and/or any | |
official actions regarding their own team. Team Captain(s) and/or the Faculty Advisor | |
must bring the issue to the Organizer’s or SAE International staff’s attention for an | |
informal preliminary review before filing an official appeal. | |
A team cannot file an appeal to cause harm to another team’s standing and/or score. | |
Cause for Appeal | |
A team may appeal any rule interpretation, own-team scoring or official actions which | |
the team feel has caused some actual, non-trivial, harm to own-team, or has had a | |
substantive effect on their score. | |
Teams may not appeal rule interpretations or actions that have not caused the team | |
any substantive damage. | |
Appeal Format | |
If a Faculty Advisor or Team Captain(s) feel their issue regarding an official action or | |
rules interpretation was not properly addressed by the event officials, the team may | |
file a formal appeal with the Appeals Committee. | |
All appeals must be filed in writing (see Appendix B) to the Organizer by the Faculty | |
Advisor or Team Captain(s) only. | |
All appeals require the team to offer twenty-five (25) points as collateral. If the | |
appeal is successful, the team will not forfeit the twenty-five (25) points. If the appeal | |
is overruled, the team will forfeit the twenty-five (25) points. | |
Appeals Period | |
All appeals must be submitted within thirty (30) minutes of the end of the flight or | |
other competition event to which the appeal relates. | |
Appeals Committee | |
When a timely appeal is received, the committee will review the claims. All | |
contentions or issues raised in the formal appeal will be addressed in a timely | |
manner. The consideration in each review is whether the actions in dispute were just | |
and in-line with the intent of the rules. Once the review is completed, a new order | |
will be issued affirming, reversing, or modifying the original determination. | |
All rulings issued by the Appeals Committee are final. | |
The Appeals Committee shall consist of a minimum of three members: the Organizer | |
or delegate, SAE International representative, and a Rules Committee member. | |
SAE Aero Design 2024 – Page: 16 | |
PROFESSIONAL CONDUCT | |
Unsportsmanlike Conduct | |
Unsportsmanlike conduct is not acceptable at SAE Aero Design events. If SAE staff | |
and/or Rules Committee members observe unsportsmanlike conduct, SAE Aero | |
Design reserves the right to assess penalty points or remove the team from | |
competition. | |
Arguments with Officials | |
Arguments with or disobedience toward any competition official may result in the | |
team’s elimination from competition. All team members may be immediately | |
escorted from the competition grounds. | |
Alcohol and Illegal Material | |
Alcoholic beverages, illegal drugs, firearms, weapons, or illegal material of any type are | |
not permitted on the event sites at any time during competition. Any violations will | |
result in the immediate expulsion of all team members and Faculty Advisor(s) of the | |
offending school, not just the team member(s) in violation. This rule applies to team | |
members and Faculty Advisors. Any use of illegal drugs or alcohol by an underage | |
person will be reported to local law enforcement authorities for prosecution. | |
Organizer’s Authority | |
The Organizer reserves the exclusive right to revise the schedule of the competition | |
and/or to interpret the competition rules at any time and in any manner required for | |
efficient operation or safety of the competition. | |
Ground Safety and Flight Line Safety Equipment | |
• | |
• | |
• | |
• | |
No open toe shoes allowed. All team members, including Faculty Advisors(s) and pilots, | |
are required to wear CLOSED toe shoes during flight testing and flight competition. | |
Smoking is prohibited. Smoking is prohibited in all competition areas. | |
Personal Protective Equipment required. All students involved in flight-line launch and | |
recovery operations for all aircraft classes must wear safety glasses. | |
Only non-visible Class 1 eye-safe (EN/IEC 60825-1 2014) lasers are allowed. Laser | |
pointers are prohibited. | |
Line etiquette | |
To make a flight attempt, teams must form a line and have their aircraft and | |
competition flightlog with them. Flightlog and Aircraft must be present at all times to | |
maintain line position. Holding a space in line without a valid aircraft or flightlog is not | |
permitted and considered unsportsmanlike conduct. If the aircraft and flightlog are not | |
present, the team will be removed from the line. Once a team uses all available flight | |
attempts, they are no longer permitted to stand in line. | |
SAE TECHNICAL STANDARDS ACCESS | |
A cooperative program of SAE International’s Education Board and Technical Standards | |
Board is making some of SAE International’s Technical Standards available to teams | |
registered for any North American CDS competition at no cost. The Technical Standards | |
referenced in the Collegiate Design Series rules, along with other standards with reference | |
value, will be accessible online to registered teams, team members, and Faculty Advisors. | |

switch mounted to the aircraft exterior, located at least 12” from the propeller. | |
REPAIRS | |
1. The original design of the aircraft as presented in the Design Report and | |
presentation must be maintained as the baseline aircraft during the competition. | |
2. In the event of aircraft damage, the aircraft may be repaired provided such repairs | |
do not drastically deviate from the baseline design. All major repairs must undergo | |
safety inspection before the aircraft is cleared for flight. | |
ALTERATION AFTER FLIGHT | |
Minor alterations are allowed after the first and subsequent flight attempts. Consult with | |
Rules Committee members to determine if desired changes may be subject to penalty | |
points. Any change made solely for safety of flight will not be subject to penalty points. | |
SAE Aero Design 2024 – Page: 22 | |
3 MISSION REQUIREMENTS AND SCORING | |
AIR BOSS | |
The Air Boss is a qualified SAE event official or appointed volunteer that manages the flight | |
line process. Their responsibilities include: | |
1 Ensuring safety of the flight line by maintaining an orderly and controlled runway. | |
2 Being the official of record for the success or failure of the flight, including takeoff | |
and landing. | |
3 Declaration of flight termination at any time during the flight attempt. | |
Air Boss, or event organizers, may continue flight operations at their discretion in continuous | |
winds up to 45 knots with gusts no greater than 65 knots. | |
PILOT STATION(S) | |
A pilot area will be defined at pilot briefing. All pilots must fly from the designated area. | |
FLIGHT ATTEMPT | |
Teams are allowed one (1) flight per attempt. There is no fixed or guaranteed number of flights. | |
A Flight Attempt is defined as each time the team brings their aircraft for mission | |
demonstration, starting when the team enters the ‘On-Deck’ area. Each team will have a | |
limited number of flight attempts for the competition, depending on local conditions. | |
A Take-off Try is defined as trying to get airborne within the time limit. | |
Airborne is defined as all parts of the aircraft are no longer touching the ground. | |
A Bounce is defined as any part of the aircraft touching the runway after becoming airborne. | |
For all competition classes the aircraft may be throttled-up/run-up for take-off, subject to | |
the following conditions: | |
• | |
• | |
• | |
• | |
Regular Class: Two (2) team members are allowed to hold the aircraft in place prior | |
to take-off roll. | |

Regular and Micro Classes: the main gear must remain on the take-off line prior to | |
release. | |
AIRCRAFT CONFIGURATION AT LIFTOFF AND DURING THE FLIGHT ATTEMPT | |
The aircraft must remain intact during a flight attempt to receive full flight score. | |
A twenty-five percent (25%) deduction from the flight score will be assessed if any of the | |
following items are observed to completely detach from the aircraft during a flight attempt. | |
• | |
• | |
• | |
Stickers | |
Tape | |
Coverings | |
SAE Aero Design 2024 – Page: 23 | |
If any components, other than a broken propellor during landing, fall off during a flight | |
attempt, the flight will be disqualified. | |
COMPETITION CIRCUIT REQUIREMENTS | |
1. During departure and approach to landing, the pilot must not fly the aircraft in a | |
pattern that will allow the aircraft to enter any of the no-fly zones. | |
2. No aerobatic maneuvers will be allowed at any time during the flight competition in | |
any competition class. This includes but is not limited to: loops, figure 8’s, | |
Immelmann, all types of rolling maneuvers, and inverted flight. | |
3. Regular and Micro Class aircraft must successfully complete a minimum of one (1) | |
complete 360° circuit around the field. See Table 3.2 for additional information. | |
4. Advanced Class has no specific flight pattern. (See Advanced Class rules concerning | |
the releasable payload drop mission element.) | |
TIME LIMITS AND MULTIPLE TAKEOFF TRIES | |
• | |
• | |
Multiple takeoff tries per flight attempt may be allowed for some classes within the | |
class-specific time allotment. Refer to Table 3.1 for specific information. | |
If an airborne aircraft returns to the ground after being airborne and is beyond the | |

SAE Aero Design 2024 – Page: 24 | |
ON-DECK AREA | |
The ‘On-Deck Area’ is an area near the flight line where teams will prepare for their flight | |
attempt. | |
• Teams will surrender one (1) flight attempt when directed to the On-Deck Area as | |
they wait for their turn to take the flight line. | |
• Teams may mount propellers, perform control surface checks, and range checks. | |
• Teams may decide, or be directed by the Airboss or Pitboss, to leave the On-Deck | |
Area for maintenance and/or technical issues but will forfeit the flight attempt. | |
• Advanced class will have three (3) minutes to turn on and connect their DAS and | |
ground systems. If the team cannot establish a connection within the time limit, they | |
will be directed to leave the On-Deck Area and forfeit the flight attempt. | |
• Teams should have enough reserve power for any expected delays. | |
• Teams will not be allowed to install their propulsion arming plugs. | |
• Motor runup and testing will not be allowed. | |
TAKE-OFF | |
Take-off direction will be determined at the discretion of the Air Boss. If possible, the takeoff direction will face into the wind. Changes in wind direction, in light and variable winds, | |
may affect the take-off direction throughout the day. SAE Aero Design reserves the right to | |
change the take-off direction at any time for weather or safety reasons. | |
1. All aircraft must remain on the runway during the take-off roll. | |
2. Table 3.2 defines distance requirements. | |
3. Making the initial turn before passing the “distance from initial start before turn” | |
requirement will disqualify the flight attempt. | |

airborne. Only one (1) launch release | |
per flight attempt is allowed. | |
LANDING REQUIREMENTS | |
A successful landing is defined as a controlled return to the ground. Aircraft must remain | |
inside the specified landing zone for each class. The aircraft may leave the landing zone only | |
if given permission by the Air Boss. | |
SAE Aero Design 2024 – Page: 25 | |
The landing zone is a pre-determined, fixed area for each class for the purpose of returning | |
aircraft to the ground. See Table 3.3 for class requirements. | |
1. The landing zones will be visibly marked prior to the start of competition. | |
2. It is the team and pilot’s responsibility to be aware of the class-specific landing zone | |
dimensions. | |
3. Any aircraft that leaves the designated landing zone or the paved runway for any | |
reason during landing is subject to a fifty percent (50%) penalty of any points earned | |
during the flight attempt prior to landing. | |
4. Any flight where the aircraft does not make initial touch down for landing inside the | |
designated landing zone is disqualified. | |
5. Touch-and-go landings are not allowed and will be judged as a failed landing. | |
6. The criterion for being within the landing zone is that no supporting part of the | |
aircraft touching the ground can be outside the landing zone. For example, a wing | |
tip or fuselage can overhang the edge of the landing zone, as long as no supporting | |
part of the aircraft is physically touching outside the landing zone. | |

Description | |
Aircraft must land in the same direction as take-off. | |
Aircraft must stop within the designated landing | |
zone to avoid a penalty (ref 3.9.3). | |
GROUNDING AN AIRCRAFT | |
1. An aircraft will be grounded if it is deemed non-flightworthy or not in compliance | |
with the rules by any SAE official, event official or a designated technical/safety | |
inspector. | |
2. Until the non-flightworthy or out-of-compliance condition has been addressed and | |
cleared by re-inspection, the aircraft will not be allowed to fly. | |
NO-FLY ZONE | |
Each competition will have venue-specific no-fly zones. The no-fly zones will be defined | |
during the pilot’s briefings. | |
1. At no time will an aircraft enter the no-fly zones, whether under controlled flight or | |
uncontrolled. | |
2. The first infraction for crossing into the no-fly zone will result in a disqualified flight | |
attempt and zero points will be awarded for that flight. | |
3. A second infraction will result in disqualification from the entire event and a loss of | |
all points. | |
4. It is the team and pilot’s responsibility to be aware of the no-fly zones and to comply | |
with all venue-specific rules. | |
SAE Aero Design 2024 – Page: 26 | |
5. If a team is unable to directionally control their aircraft and it is headed towards or is | |
in a no-fly zone, the Judges and/or Air Boss may order the pilot to intentionally crash | |
the aircraft to prevent it from endangering people or property. This safety directive | |
must be followed immediately, if ordered by the officials. | |
FLIGHT RULES ANNOUNCEMENT | |
Flight rules will be explained before the flight competition begins during a pre-competition | |
pilots’ meeting. | |
FLIGHT RULES VIOLATIONS | |
1. Violation of any flight rule may result in the team being eliminated from the | |
competition. | |
2. All members of an eliminated team may be escorted from the grounds. | |
LOCAL FIELD RULES | |
In addition to competition rules, the local flying club may have additional rules in place at | |
the event flying field. | |
1. Club rules will be obeyed during the competition. | |
2. If club rules conflict with competition rules, it is the responsibility of the Team | |
Captain(s) and/or Faculty Advisor to bring attention to the conflict and follow the | |
appeals process to resolve the conflict. | |
COMPETITION SCORING | |
A team’s final, overall score is composed of scores in the following categories: | |
1. Technical Design Report (Design Report and Drawing) | |
2. Presentation | |
3. Flight Event | |
4. Penalties | |
Teams must participate in the design report, presentation, and flight event categories to be | |
included in the competition for overall score. Passing Requirements Check & Safety and | |
Airworthiness inspection counts as participating in the Flight Event. | |
AIRCRAFT EMPTY WEIGHT DEFINITION | |
All aircraft parts that are not payload, as defined in the relevant class’s section, contribute to | |
the empty aircraft weight, including, but not limited to: airframe, receiver, electronics, | |
batteries, hardware, brackets, straps, and other associated features. | |
SAE Aero Design 2024 – Page: 27 | |
4 DESIGN REPORT | |
The Design Report is the primary means for a team to convey the story of how their aircraft is | |
the most suited design to accomplish the mission. The Design Report should explain the team’s | |
thought processes and engineering philosophy that drove their conclusions. | |

5 FLIGHT DEMONSTRATION READINESS REVIEW | |
Prior to conducting expensive test campaigns, professional engineers are required to complete | |
technical readiness reviews with senior technical leadership and independent reviewers to | |
ensure the team, hardware, and software are ready to complete test objectives in support of a | |
program’s mission milestones. These reviews require the engineers to possess a well-developed | |
ability to synthesize issues, detail outstanding items, evaluate risk and communicate effectively. | |
The competition technical presentation will now be focused on a Flight Demonstration (Demo) | |
Readiness Review (FDRR) allowing teams the opportunity to demonstrate they are ready to | |
perform safely in the competition’s flight operations. Teams can obtain a maximum FDRR score | |
of fifty (50) points. The score shall be comprised of scores from each judge based on the judges’ | |
evaluation of the technical content and the team’s readiness to compete. | |
PRESENTATION REQUIREMENTS | |
1. The FDRR shall be timed with a follow-on, timed "Question and Answer" (Q&A) | |
period. The time limits are detailed in Table 5.1 (Regular and Micro Class) and Table | |
5.2 (Advanced Class). | |
2. The FDRR shall be delivered in English. | |
3. The FDRR shall address, but is not limited to: demo overview, preflight predictions, | |
demo hardware & software pedigree and readiness, competition first time events & | |
demo risks, outstanding major milestones prior to competition, demo team roles | |
and responsibilities, and post flight risk planning. | |
• A First Time Event (FTE) is defined as any subsystem tests, assembly & | |
integration, flight testing, new conditions, new pilot, or any other occurrence | |
that may be encountered during competition weekend for the first time. | |
4. The FDRR is limited to student team members only. Non-team member pilot or | |
Faculty Advisors can attend but are prohibited from participating in the setup, | |
delivery, and/or the Q&A. | |

6 REQUIREMENTS CHECK & SAFETY AND AIRWORTHINESS INSPECTION | |
Requirements Check & Safety and Airworthiness Inspection of all aircraft will be conducted | |
using the published checklists for each class for the current year. The checklists can be found at: | |
www.saeaerodesign.com/go/downloads | |
Safety and Airworthiness Inspection is the process of checking each aircraft for any issues or | |
problems that could cause a safety problem in flight or on the ground. | |
Requirements Check is the process of checking all aircraft for: | |
• | |
• | |
• | |
Compliance with all General aircraft requirements. | |
Compliance with all Class-specific requirements. | |
The aircraft presented matches the design submitted by the team. | |
All aircraft must pass the Requirements Check & Safety and Airworthiness to compete. Per the | |
Statement of Compliance, teams shall present a fully completed Requirements Check & | |
Safety and Airworthiness Inspection for their aircraft submitted on SAEStars by the Faculty | |
Advisor or Team Captain. Teams cannot begin the inspection process without meeting this | |
requirement. Inspectors will confirm the team has fully inspected their aircraft. | |
Inspectors will be given a list of five (5) to seven (7) requirements to spot check, instead of | |
checking all items. These will be randomly chosen before the event. Even though items are | |
being spot checked, teams must comply with all items at all times. | |
AIRCRAFT CONFORMANCE TO 2D DRAWING | |
During Technical Inspection, the aircraft will be inspected and measured for conformance to | |
the 2D drawing presented in the Design Report. | |
1. At a minimum, aircraft length, wingspan and height dimensions will be measured | |
and compared to the 2D drawing. | |
2. Aircraft will have the actual empty CG compared to the empty CG presented in the | |
2D drawing. | |
DEVIATIONS FROM 2D DRAWING | |
Any deviation in construction of the aircraft from the submitted 2D drawing, must be | |
reported in writing. For Advanced and Regular Class aircraft, there is no need to report | |
deviations in the length (L), width (W), and height (H) of the aircraft, if the following is | |
satisfied, where dimensions are in inches: | |
�𝐿𝐿𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎 − 𝐿𝐿𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 � + �𝑊𝑊𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎 − 𝑊𝑊𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 � + �𝐻𝐻𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎 − 𝐻𝐻𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 � ≤ 𝑋𝑋 𝑖𝑖𝑖𝑖𝑖𝑖ℎ𝑒𝑒𝑒𝑒 | |

INSPECTION OF SPARE AIRCRAFT AND SPARE AIRCRAFT COMPONENTS | |
1. All spare aircraft and spare aircraft components (wings, fuselages and tail surfaces) | |
must be presented for inspection. | |
2. Teams may submit up to two (2) complete aircraft at inspection on Friday. | |
3. Additional spare aircraft and parts beyond two (2) sets may be submitted for | |
inspection on Saturday and Sunday. | |
AIRCRAFT MUST MAINTAIN COMPLIANCE THROUGHOUT THE COMPETITION. | |
1. All aircraft must meet all Requirements Checks & Safety and Airworthiness | |
requirements throughout the competition. | |
2. Any official may request an aircraft be re-inspected if a general, class configuration, | |
or safety/airworthiness requirement problem is seen on the aircraft at any time | |
during the event. | |
3. This includes any errors or omissions made by officials during inspection. | |
REQUIREMENTS CHECK & SAFETY AND AIRWORTHINESS INSPECTION PENALTIES | |
1. If a team fails the spot check process for any of the General Aircraft requirements or | |
Class requirements, there will be a point penalty for each item failed. The aircraft | |
must be brought into compliance to compete. | |
2. SAE Aero Design reserves the right to assess the point penalty on any requirement | |
item found during inspection, even if the item is not on the spot check list. | |
3. Any Requirements Check failure involving penalty points will be confirmed by a | |
Rules Committee member. | |
4. No additional penalty points will be assessed for a team’s second aircraft that has | |
the same requirements failure as the first aircraft. | |
5. If a Requirements Check item failure is found on an aircraft after inspection or | |
during flight rounds, the point penalty will be applied and any flight score earned | |
while the aircraft was non-compliant will be zeroed. The aircraft will have to be | |
brought into compliance before flying again. | |
6. There are no penalty points for failing any Safety or Airworthiness item. However, | |
the team must correct any failures before the aircraft is allowed to fly. Flight points | |
earned while the aircraft was not in compliance with Safety and Airworthiness | |
requirements may be subject to being zeroed. | |
SAE Aero Design 2024 – Page: 37 | |
7 REGULAR CLASS DESIGN REQUIREMENTS | |

email by February 15th, 2024. SAE Rules Committee will work with teams to deconflict if | |
multiple teams request similar frequencies. | |
DATA ACQUISITION SYSTEM (DAS) | |
Advanced Class Primary Aircraft shall have a Data Acquisition System (DAS) to record altitude | |
and be used by the team to locate the appropriate target landing zone. All communication | |
between the payload specialist and any pilot must be in English. | |
1. Using a ground receiver station, the team must display the real-time altitude of the | |
aircraft to the Payload Specialist and the flight judge in at least 1.0 inch text. | |
2. Team must automatically record, and immediately display the altitude (ft) at the | |
moment of PADA release in at least 1.0 inch text. The indicator must remain visible | |
for the remaining duration of the flight. | |
3. The DAS recording must be performed on the ground station and must support play | |
back for review on demand. | |
4. Altitude must be measured in feet with a display precision of at least one (1) ft and | |
an accuracy error of less than ten (10) ft. | |
5. The DAS system must use a discrete and removable Red arming plug to apply power. | |
This arming plug is subject to the Section 2.20 requirements. One Red arming plug | |
can be used for both DAS and FPV. | |
6. DAS equipment may also have a reset switch, if desired. If a manual reset switch is | |
used, it must be located externally at least 12 inches behind the propeller in the | |
longitudinal direction. A wireless DAS reset system is allowed. | |
7. DAS systems shall not use the same 2.4 GHz band as the flight control system, unless | |
the telemetry being used is part of the radio control system being used. A DAS built | |
into the radio control system must meet all DAS rules requirements. | |
DAS FAILURES | |
Any DAS failure during a flight attempt is considered a failed flight attempt and receives zero | |
(0) points. | |
Example: A team has flown four (4) times successfully and on the 5th attempt the | |
Primary Aircraft takes-off successfully, makes a successful release, but the DAS altitude | |
reading malfunctions. The flight attempt will NOT be considered a qualified flight and | |
the team will receive zero (0) credit for PADA or static payload for flight 5. | |
FIRST PERSON VIEW SYSTEM (FPV) | |

prevent conflicts. | |
2. The primary pilot must fly visually only (no FPV goggles or ground station reference). | |
3. FPV systems CANNOT use the same frequency as the flight control system. Use of | |
2.4 GHz for FPV video is prohibited. | |
4. The FPV system must use a discrete and removable Red arming plug to apply power. | |
This arming plug is subject to the Section 2.20 requirements. One Red arming plug | |
can be used for both DAS and FPV. | |
PAYLOAD SPECIALIST | |
The Payload Specialist is responsible for releasing the PADA from the Primary Aircraft. | |
1. The Payload Specialist must be a single team member. The Payload Specialist should | |
not rely on having a line-of-sight view to the aircraft or target(s). | |
2. Neither the primary aircraft pilot not the PADA pilot may have access to or activate | |
any PADA release, and the release cannot be connected to the pilot’s R/C | |
transmitters in any way. | |
3. The PADA release must be manually activated by the Payload Specialist or by an | |
automatic release system that is part of the Primary Aircraft electronics. | |
4. If an automatic release system is used, it must have a manual override controlled by | |
the Payload Specialist. | |
5. Teams may activate the payload release system using a second 2.4 GHz radio system | |
or some other method based on their DAS or telemetry system. | |
POWERED AUTONOMOUS DELIVERY AIRCRAFT RELEASE PROCEDURES | |
1. PADA release must be at least 200 feet away from the center of the runway, | |
measured parallel to the runway. | |
2. Teams must release the PADA at an altitude no greater than 50 ft. | |
3. Teams have as many passes as needed, as the PADA is released within four (4) | |
minutes of throttle-up, lands within five (5) minutes of throttle-up. | |
4. The Primary Aircraft must come in for landing once the PADA is released. | |
5. A single PADA shall be successfully released during each flight attempt. Failure to | |
release a PADA successfully and intentionally shall disqualify the entire flight | |
attempt. A successful release is defined as: | |
• Being within four (4) minutes of primary aircraft throttle-up | |
• Complying with Section 8.15.1 and 8.15.2 as shown in Figure 8-1. | |
• The PADA must attain stable flight after release. | |

GROUND TRANSPORT VEHICLE DEMONSTRATION EVENT PROCEDURE | |
At the conclusion of all flight activities, before the award ceremony, teams shall have eight (8) | |
minutes to demonstrate their GTV’s ability to transport water in the following manner: | |
1. Each team will be set up in a designated area of the runway with sufficient | |
separation from other teams to avoid interference. | |
2. On one side of the demonstration zone will be the unassembled GTV in the impound | |
box and the team’s main water storage container(s). Stationed on the other side of | |
the zone (approx. 30 feet away) shall be the team’s empty destination water storage | |
container(s). Containers shall be positioned approximately as shown in Figure 8-2. | |
3. No more than three (3) team members may take part in the assembly and | |
demonstration, including the GTV driver. Teams may split personnel between the | |
start and destination sides of the area however they choose, but no team member | |
may switch sides during the demonstration. | |
4. When the demonstration begins, the team shall assemble their GTV, load it with | |
water from the main water storage container and navigate to the other side of the | |
runway. Once the GTV has completely passed the finish line, the team member(s) on | |
the other side of the runway shall unload the water into the destination storage | |
container(s). Only water successfully delivered by the GTV within the time limit shall | |
be measured for score. | |
5. Teams may handle the water storage containers, but neither the main nor | |
destination water storage containers may be moved during the demonstration. | |
6. Multiple trips across the demonstration zone are allowed. | |
7. Team members on the starting side may only refill the GTV after it has completely | |
left the demonstration zone. | |
8. The GTV may be autonomous or manually controlled. If the team controls the GTV | |
via a transmitter when it is within the demonstration zone, the GTV shall be | |
considered manually controlled for the entirety of the demonstration. Teams may | |
touch, control, or manipulate an autonomous GTV when it is outside of the | |
demonstration zone and the GTV shall still be considered autonomous. Touching the | |
GTV while it is within the demonstration zone is prohibited under all circumstances. | |
9. Obstacles will be placed in the demonstration zone approximately as shown in | |
Figure 8-2. The obstacles may be up to three (3) inches in height. | |

ADVANCE CLASS SCORING | |
To participate in the flight portion of the competition, each team is required to have | |
submitted AND received a score for both Design Report and Oral Presentation. | |
The team’s Final Flight Score (FFS) is the sum of the team’s top three (3) flight scores | |
achieved during competition (FS1, FS2, and FS3) and the GTV event score. Teams receive | |
points based on the water the primary aircraft successfully carries each flight and a flat score | |
every time a PADA successfully lands in the designated landing zone, with a bonus for | |
distance to the center derived from the team’s predictions. Finally, teams who deliver | |
enough parts via PADAs to assemble a working GTV will have the opportunity to score points | |
by transporting water carried previously by the primary aircraft in a ground demonstration. | |
