What is the legal height limit for flying a drone in non-controlled airspace?

The legal height limit for flying a drone in non-controlled airspace is 400 feet (120 meters) above the ground level. This regulation is crucial for ensuring the safety of both manned and unmanned aircraft, as it helps to prevent potential collisions and maintains a clear airspace for manned aircraft operations.

By adhering to this height limit, drone operators can safely conduct their flights while minimizing interference with other aircraft, especially given that most small aircraft typically operate at altitudes above this threshold. Furthermore, this regulation is designed to ensure that drones remain within the visual line of sight of the operator, further enhancing safety and operational effectiveness.

In some specific scenarios, such as when flying near buildings, operators may need to adjust their operations accordingly, but the standard limit of 400 feet remains a fundamental guideline for drone flights in non-controlled airspace.
