# DARPA Lift Challenge Virtual Q&A - December 4, 2025 Source: https://www.youtube.com/watch?v=iJZJFn30kis Recap page: https://rapidrecap.app/video/iJZJFn30kis Generated: 2025-12-05T19:40:43.9+00:00 --- ## Quick Overview The DARPA Lift Challenge Virtual Q&A provided critical details regarding the competition timeline, eligibility, aircraft design constraints, and event logistics, confirming the team application launch on January 5th, 2026, and emphasizing that the core metric for scoring is the payload-to-weight ratio, not absolute weight carried. **Key Points:** - The team application link launches on January 5th, 2026, requiring only one US person or US registered entity to submit initial information, with site attendance capped at 10 members per team. - Critical deadlines include submitting a draft concept paper by the end of January, build pictures in March, and final deliverables (flight test video, final concept paper, proof of FAA certification) by May, which is also when the application period closes. - Aircraft weight must be below 55 lbs to allow rapid testing under Part 107 regulations, and the payload must be at least 110 lbs; the competition scoring focuses on the payload-to-weight ratio. - The flight course involves flying four full nautical miles before dropping the payload, followed by a final unloaded nautical mile, all while maintaining an altitude of 350 plus or minus 50 ft. - The Remote Pilot in Command (RPIC) must possess a US FAA pilot certification, as foreign certifications are not accepted, and DARPA provides no direct funding but is creating a contributor portal for sponsorship. - The payload consists of standard cast iron weight plates (45, 35, 25, 10, five, and two and a half pounds) which must be collocated, and the aircraft must take off vertically. - DARPA is collaborating with Flight Test, potentially co-locating the June 2026 competition with their flagship event, Flightfest, in Malvern, Ohio, which will feature public attendance and food availability. **Context:** This virtual Q&A session, hosted by Donna, provided essential updates and clarifications for the DARPA Lift Challenge, following previous announcements where participants were expected to have reviewed the rules and FAQs. The session addressed over 300 submitted emails and aimed to clarify key areas including the competition timeline, eligibility requirements for US and foreign team members, aircraft design parameters like the 55 lb weight constraint, and the structure of the final competition event scheduled for Summer 2026. ## Detailed Analysis The DARPA Lift Challenge aims for a simple payload delivery five nautical miles away and a return, emphasizing real-world applicability and safety, necessitating aircraft weight under 55 lbs to align with Part 107 testing, although special authority (44-807) is needed for operations above this limit. The competition scoring prioritizes the payload-to-weight ratio, requiring a minimum 110 lbs payload. Aircraft design allows for modified COTS drones, requires vertical takeoff, and mandates that the center of the aircraft lands within a 5-ft radius circle for takeoff/landing, while all components except the jettisoned weights must remain for the final unloaded mile. The flight course is approximately 50 ft wide and a quarter mile long, requiring teams to complete four full nautical miles before dropping the collocated barbell weight plates, followed by a final unloaded mile, all while staying within 350 +/- 50 ft altitude. The event will be open to the public, and collaboration with Flight Test suggests a potential venue at Flightfest in Malvern, Ohio, in June 2026, where teams will be assigned specific 90-minute flight windows to execute their attempts. ### Competition Timeline - Team application link launches January 5th, 2026 - Draft concept paper due end of January - Build pictures due in March - Final deliverables and application close in May - Formal invitations to compete issued in June. ### Eligibility and Participation - Only one US representative needed for initial application - Foreign members allowed unless on the restricted country list - Government/military designs cannot be previously government-funded - Each team requires an ARPIC with US FAA pilot certification. ### Aircraft Design Constraints - Aircraft weight must be below 55 lbs for rapid testing under Part 107 - Total aircraft and payload attachments must be under 55 lbs at takeoff - Vertical takeoff required; no sliding or rolling takeoffs - Energy sources can be used for propulsion/controls but not for lift; transformation is allowed. ### Payload and Scoring - Payload uses standard cast iron weight plates, must be collocated, and orientation does not matter - Scoring is based on the payload-to-weight ratio, aiming for the best ratio above a 110 lbs minimum payload - DARPA furnishes one payload tracker (shaped like a weight plate); teams supply the FAA flight ID tracker. ### Event and Course Overview - Competition is outdoors, flying in present weather conditions up to rule limits - Each team receives one morning and one afternoon 90-minute flight window - The course requires flying four miles before payload drop, then one final unloaded mile, maintaining 350 +/- 50 ft altitude. ### Regulations and Support - Teams must follow FAA Part 107 for sub-55 lb operations or obtain a 44-807 special authority for heavier systems - Autonomy requires a human pilot backup, but AI/autonomy use is not a focus unless it aids the P/W ratio - DARPA will not claim IP, and prize money usage is unrestricted by DARPA.
