What is the main purpose of marshaling during aircraft operations?

Marshaling serves a critical role in ensuring the safe movement of aircraft on the ground. The primary purpose is to prevent collisions by providing clear and effective communication between ground personnel and the flight crew. Marshallers use specific signals to guide aircraft during taxiing and parking maneuvers, ensuring that the aircraft maintains the correct distance from other aircraft, vehicles, and structures on the ramp. This function is essential for maintaining safety in busy airport environments where multiple aircraft and ground operations are occurring simultaneously.

While other options like initiating a flight plan, loading passengers and cargo, and conducting safety checks are important aspects of aircraft operations, they do not directly pertain to the specific objective of marshaling. The focus of marshaling is entirely on controlling and directing the physical movement of aircraft to prevent accidents and ensure safe operations on the ground.
