CAA Drone Theory Practice Test

Which of the following tall structures should drone pilots be cautious of?

1. Buildings, antennas, and trees

2. Towers, bridges, and cranes

3. Crane, masts, and wires

4. Wind turbines, silos, and radio towers

The correct answer is: Crane, masts, and wires

Drone pilots should exercise caution around cranes, masts, and wires due to several factors that can pose risks during flight operations. Cranes are often located at construction sites and can have long-reaching booms that may not be immediately visible. Their height and movement can create hazards that drones must avoid, as collisions could lead to drone damage or loss. Masts, which are typically used for broadcasting signals, can be very tall and slender. They are often difficult to see from a distance, especially in rural or less populated areas. Their height means that drones need to maintain safe distances to avoid the risk of crashing into them. Wires, such as power lines or telephone lines, are particularly dangerous for drone pilots. These can be nearly invisible depending on the lighting and surroundings, and collisions with wires can result in loss of control and potentially damaging crashes, as well as personal safety hazards. In summary, the structure types listed highlight common and significant risks associated with drone operations, making it critical for pilots to remain aware of their surroundings and adhere to safety practices to mitigate these dangers.
