What does a marshaller do?
The Marshaller strands in front of the place where the plane has to stop. It is a one-on-one visual communication between the marshaller and the pilot. The marshaller should wear protective and reflective clothing and have colored marshalling bats, colored gloves, or light cones. With these attributes, the marshaller can give different signals.
Marshalling is often used at smaller airports that do not have an automatic pilotage system.
The marshaller signals to the pilot to keep turning, slow down, stop, shut down the engines, leading the aircraft to its parking position or the other way around and leading the aircraft to the runway. This is all about airplanes but Marshallers also guide helicopters. They give take-off and find clearances land for the helicopters.
