FAA Part 107 Remote Pilot (UAG)RegulationsEasy
A remote pilot in command is flying a small UAS under Part 107. What is the maximum altitude above ground level at which the aircraft may normally be operated?
- A200 feet AGL
- B400 feet AGL
- C500 feet AGL
- D1,000 feet AGL
Show answer & explanationAnswer & explanation
Correct answer: B. 400 feet AGL
14 CFR 107.51 limits sUAS operations to 400 feet above ground level, unless the aircraft is flown within 400 feet of a structure and remains within 400 feet laterally of that structure, or a waiver is obtained.
Why the other options are wrong
- A. 200 feet is not the regulatory altitude limit.
- C. 500 feet is the standard manned aircraft minimum altitude over congested areas, not the sUAS ceiling.
- D. 1,000 feet greatly exceeds the sUAS altitude limit.
Maximum Altitude Rule
Small UAS operations are limited to 400 feet AGL unless within 400 feet of a structure or under a waiver.
- 400 ft AGL standard limit
- Structure exception allows 400 ft above structure top
- Waivers can authorize higher altitudes
