What does FBO stand for in an airport context?

In the context of an airport, FBO stands for Fixed Base Operator. This term refers to a commercial business granted the right by an airport to provide various services to private aircraft operators. These services typically include fueling, hangaring, maintenance, and other support services for general aviation. Fixed Base Operators serve as a critical support hub for pilots and aircraft owners, providing essential amenities and logistical support at numerous airports.

The other terms do not accurately reflect the common usage of FBO in aviation. For instance, "Foreign Base Operator" and "Flight Base Operator" do not align with the recognized terminology within the aviation industry. "Flight Business Operations" is not a standard term either, as it does not specifically denote the range of services associated with an FBO. Thus, the designation of Fixed Base Operator is widely accepted and understood in the aviation sector.
