Drone Pilot Practice Exam

Which flight condition results in a higher potential for a stall?

1. Descending flight

2. Climb at a steep angle

3. Level flight

4. Cruising at altitude

The correct answer is: Climb at a steep angle

A climb at a steep angle results in a higher potential for a stall due to the increased angle of attack of the aircraft's wings. When an aircraft climbs steeply, it often requires a greater angle of attack to maintain lift. However, if this angle exceeds the critical angle for the particular aircraft, airflow over the wings can separate, leading to a loss of lift and resulting in a stall. In contrast, descending flight tends to lower the risk of stalls as the aircraft is generally flying at a lower angle of attack. Level flight keeps the aircraft within a safer operational parameter where lift can be maintained effectively, and cruising at altitude typically allows for steady, controlled flight that minimizes the potential for stalls. Therefore, understanding the dynamics of steep climbs is crucial for drone pilots to maintain control and prevent stalling.
