Who is considered an operator at an airport?

The definition of an operator at an airport encompasses any person who has actual physical control of an aircraft or motor vehicle. This includes not only licensed pilots who are flying the aircraft but also ground personnel who may operate ground vehicles used for servicing or transporting aircraft. The emphasis on "actual physical control" signifies the responsibility of the individual over the vehicle or aircraft, which is a critical aspect of ensuring safe operations in and around the airport environment.

Other choices narrow the definition either too much or focus on specific groups, leading to incomplete concepts of operational control. Defining an operator solely as anyone with a flight plan overlooks those who might operate ground vehicles but are not flying the aircraft. Limiting it to licensed pilots excludes ground vehicle operators who perform essential roles on the ramp. Lastly, stating that only cargo truck drivers qualify as operators restricts the definition even further, missing the broader category of individuals involved in aircraft and vehicle control. Therefore, the correct identification of an operator effectively encompasses a wider range of responsibilities important for airport operations.
