What role do marshallers perform on the airfield?

Marshallers play a crucial role in ensuring the safe and efficient movement of aircraft on the airfield. Their primary responsibility is to direct aircraft using hand signals, which helps pilots navigate in tight spaces, especially during taxiing, parking, or when preparing for takeoff. By providing clear and visible instructions, marshallers help to prevent accidents and ensure that all aircraft movements adhere to safety protocols.

In contrast, the other choices represent roles that are not part of the marshalling function. Managing passenger check-in is typically handled by customer service agents, whereas handling in-flight meals falls under the responsibilities of airline staff or catering services. Additionally, runway inspections are conducted by specialized personnel to ensure the safety and operability of the runways, which is distinct from the marshalling responsibilities on the airfield.
