Drone exam · Meteorology

A route passes through a gap between two tall buildings. Wind outside the gap is moderate. What local effect should be anticipated?

Answer

The flow can accelerate and become more turbulent in the gap. Use extra stand off distance, reduce exposure, or choose another route if the aircraft margin is small.

Explanation

Terrain and structures can channel airflow. A site wide wind reading does not guarantee the same speed or smoothness inside a constricted path.
