Drone exam · Operational procedures

A route deviation remains inside the planned operational volume, while a later motor warning suggests the aircraft may not remain controllable. Why should the procedures treat these situations differently?

Answer

The first can be handled with a contingency procedure designed to return the operation to a normal state. The second may require an emergency procedure focused on protecting people and limiting the consequences of a loss of control.

Explanation

Using one generic 'emergency plan' for every abnormal event makes it harder to choose proportionate actions. Contingencies and emergencies need different triggers and priorities.
