What is the purpose of a Wave-Off in FARP operations?

The purpose of a Wave-Off in Forward Arming and Refueling Point (FARP) operations is to ensure the safety and efficiency of aircraft during critical landing and refueling phases. When a Wave-Off is initiated, it serves as a directive to divert aircraft that are approaching for landing, typically due to unsafe conditions on the ground or other operational reasons that would prevent a safe landing and refueling process.

This procedure is crucial in maintaining the safety of both the personnel involved in FARP operations and the aircraft themselves. Depending on factors such as weather, visibility, or congestion on the ground, the Wave-Off provides a clear and immediate signal for pilots to abort their approach and reposition for another landing attempt, thereby avoiding potential accidents.

The other options focus on different aspects of FARP operations, such as fueling readiness or the initiation of refueling, but do not encompass the primary function of a Wave-Off, which is centered around managing aircraft landings safely.
