CAA Drone Theory Practice Test 2025 – Complete Exam Prep

The recommended maximum altitude for commercial drone operations aligns with regulations set by aviation authorities in many regions, including the UK Civil Aviation Authority (CAA). This altitude limit is typically set at 120 meters (394 feet) above ground level. The rationale behind this guideline is to ensure safety by minimizing the risk of conflict with manned aircraft, which usually operate at higher altitudes. Maintaining this limit also allows for better control and visibility of the drone within the operator’s line of sight, which is a crucial aspect of safe drone operations.

Additionally, staying within this altitude limit helps to ensure compliance with airspace regulations and enhances operational safety by preventing potential interference with aircraft that are taking off, landing, or cruising in the vicinity. Therefore, the choice of 120 meters is not only a guideline but a standard aimed at ensuring both safety and effective separation from other aerial traffic.
