CAA Drone Theory Practice Test

Which type of aircraft should you watch for when flying below 120m?

1. Commercial airliners

2. Small aircraft and drones

3. Military jets

4. Helicopters only

The correct answer is: Small aircraft and drones

When operating a drone at altitudes below 120 meters, small aircraft and drones are the primary concern. This is because most small aircraft, such as general aviation planes, often operate within lower altitudes, particularly during takeoff, landing, or in specific traffic patterns in the vicinity of airports. Similarly, other drones may be operating in the same airspace, especially in urban areas or designated drone zones. Small aircraft typically fly at altitudes that intersect with drone operations; therefore, awareness of their presence is crucial for maintaining safety and preventing mid-air collisions. The low altitude, combined with the increasing prevalence of drones in various environments, emphasizes the importance of vigilant observation for these types of aircraft when flying your drone. In contrast, commercial airliners and military jets generally operate at much higher altitudes, typically well above 120 meters, making them less of a concern for drone pilots at lower altitudes. While helicopters can fly at lower altitudes, they are not as commonly encountered as small aircraft and drones in many flying situations. Hence, focusing on small aircraft and drones provides the most relevant safety consideration for drone operators flying below 120 meters.
