The pilot sees repeated compass and GNSS warnings near metal fencing. The aircraft can still hover, and the client asks whether the pilot can just fly slowly. Why is slow flight not an adequate mitigation by itself?

Answer

The pilot should not rely on slow flight to solve navigation uncertainty. The safer action is to move away from the interference, wait for stable navigation, use an appropriate control mode only if trained and safe, or cancel the flight.

Explanation

Compass and GNSS problems can affect heading, position hold, return to home, and stability. Flying slowly may reduce kinetic energy, but it does not fix bad navigation inputs. A flyaway risk should be controlled before takeoff or before the aircraft leaves a recoverable area.
