What is the acceptable maximum altitude for sUAS flights under Part 107?

The correct answer, which specifies the acceptable maximum altitude for sUAS (small Unmanned Aircraft Systems) flights under Part 107, is set at 400 feet above ground level. This regulation is designed to maintain safe distances from manned aircraft, which typically operate at higher altitudes. By limiting sUAS operations to 400 feet, the Federal Aviation Administration (FAA) can help minimize the risk of mid-air collisions and ensure the safety of all airspace users.

This altitude restriction also allows for some flexibility in operations—if a sUAS is flown near a structure, it can operate up to 400 feet above the top of that building, allowing for effective surveying and inspecting tasks while remaining compliant with safety regulations. Understanding these altitude limits is crucial for sUAS operators to ensure they are adhering to federal laws and regulations, maintaining safety in the airspace, and managing their flights responsibly.
