Describe the procedure for guiding an aircraft into its parked position.

Using hand signals and ensuring the path is clear is the correct procedure for guiding an aircraft into its parked position. This method allows for direct communication between the ramp marshal and the flight crew, ensuring that the pilot is aware of all necessary maneuvers during the parking process. Hand signals are vital because they provide clear visual cues in environments where verbal communication may be hampered by noise or distance.

The ramp marshal stands in a designated position, using standard hand signals to direct the aircraft's approach, typically signaling for the aircraft to move forward, turn, or stop as necessary. This method of guidance is essential for maintaining safety and accuracy in positioning the aircraft, as it allows the ramp marshal to monitor the surroundings and ensure that the path is clear of any obstacles or personnel.

In contrast, relying solely on automated systems, lights, or waiting for pilot alignment without assistance does not provide the same level of safety and communication. These alternatives may lack the human oversight necessary to ensure a clear and safe path for the aircraft, which is crucial in busy airport environments. Thus, using hand signals while ensuring the path remains unobstructed is the established best practice for guiding aircraft safely into their designated parking positions.
