People, who are responsible for guiding airplanes in the right position, are known as marshallers. They do so by applying marshalling signals.

The professional responsible for "guiding" a plane on the airport ramp is officially called an Aircraft Marshaller. Also known as a ground movement coordinator, their primary job is to provide visual signals to pilots to help them navigate tight spaces and park the aircraft precisely at the gate or a designated parking stand. They use specialized tools, such as orange "wands" (which are illuminated at night), to signal commands like "turn left," "slow down," or "emergency stop." Marshalling is a critical safety role because pilots have limited visibility of the area directly in front of and below the aircraft's nose. In addition to guiding the plane, marshallers often perform "Foreign Object Debris" (FOD) inspections of the gate area before an arrival to ensure nothing can be sucked into the engines. While many modern airports now use automated "Visual Docking Guidance Systems" (VDGS), human marshallers remain essential for handling non-standard parking maneuvers, technical issues, or smaller regional airfields.
