Drone exam · Airspace restrictions

During a mapping flight, an observer hears a helicopter but cannot see it because of trees. The drone is near the edge of visual range. What should the pilot do?

Answer

The pilot should stop extending the flight, bring the drone closer or land, and scan for the helicopter before deciding whether the operation can continue.

Explanation

Sound is an early warning, not a reliable position fix. Trees, wind, and terrain can hide a low aircraft until late. Reducing the drone's range and altitude gives the pilot more time and options.
