In aviation, color codes are utilized to quickly convey specific roles and responsibilities among personnel. The yellow color code is specifically associated with aircraft handling officers and plane directors. This designation is critical because these individuals are responsible for directing the movement of aircraft on the ground, ensuring that they are safely and efficiently maneuvered. Their role includes guiding pilots during taxiing, parking, and other ground operations, which is essential to maintaining high safety standards on the airport ramp.

While the other roles listed, such as ground support equipment troubleshooters, crane operators, and flight deck safety personnel, have their own specific responsibilities, they are represented by different color codes. Understanding these color codes helps to enhance communication and safety among the diverse activities happening simultaneously at an airport.
