What is the maximum flight altitude for a UAS under Part 107 regulations?

Under Part 107 regulations, the maximum flight altitude for a Unmanned Aircraft System (UAS) is set at 400 feet Above Ground Level (AGL). This altitude limit is established to ensure the safe operation of UASs, particularly in relation to manned aircraft.

Flying at or below this altitude helps to minimize the risk of collisions with other aircraft that may be operating in the same airspace. Additionally, if a UAS is flown within a 400-foot radius of a structure, it can legally operate up to 400 feet above the structure's immediate height, allowing for flexibility while maintaining overall safety standards.

This regulation emphasizes the importance of altitude awareness in UAS operations to avoid conflicts with manned aircraft and to adhere to airspace requirements. Understanding this maximum altitude is crucial for remote pilots to operate within the legal framework established by the FAA.
