What must a pilot ensure during ground reference maneuvers in terms of safety?

During ground reference maneuvers, it is essential for pilots to maintain altitude above congested areas to ensure safety. This practice is crucial because flying over populated areas increases the risk to people on the ground in the event of an emergency or an unexpected issue with the aircraft. By keeping a safe altitude, pilots can reduce the potential impact on individuals or property below, thus adhering to safety regulations and best practices.

While avoiding busy flight paths is also a critical consideration, the primary focus in this context is on maintaining a safe altitude. Therefore, while both practices are important for overall safety, the core requirement during ground reference maneuvers specifically emphasizes altitude considerations over congested areas. Understanding this principle helps pilots make informed decisions that prioritize safety during flight operations.
