Air marshalling is primarily used for what purpose?

Air marshalling is primarily a ground service function that involves signaling between ground personnel and the pilot. This role is crucial for ensuring the safe and efficient movement of aircraft on the ground, particularly during taxiing, parking, and takeoff preparations. The ground marshaller uses visual signals, such as hand gestures and waving flags, to communicate specific instructions to the pilot, guiding them into the appropriate position on the tarmac. This communication is vital in an environment where radio communication may not always be feasible, ensuring that pilots receive clear and unambiguous directions.

Other functions of ground personnel, such as managing fuel or handling emergency procedures, do play important roles, but they do not encompass the primary responsibility of air marshalling. While delivering food services is essential for passenger comfort, it is unrelated to the marshalling process. Thus, the focus on signaling and directing aircraft on the ground makes the role of marshalling critical for aviation safety and efficiency.
