What is the maximum altitude allowed for a sUAS under Part 107?

• A. 300 ft AGL
• B. 400 ft AGL
• C. 500 ft AGL
• D. 600 ft AGL

Answer: (B)

The main idea here is the altitude ceiling for flying a small UAS under Part 107. You may not operate higher than 400 feet above the ground. This height is measured as altitude above ground level (AGL), not above sea level or above the takeoff point. So if you’re on rising terrain, you could be higher above sea level, but your drone’s height above the surface must stay within 400 feet. This limit helps keep drone operations clear of most manned aircraft and within a range where pilots can maintain visual contact. If you need to fly higher, you’d have to obtain a waiver from the FAA and follow the required coordination.
