Which of the following best describes the role of an FBO?

The role of a Fixed Base Operator (FBO) is primarily focused on providing a variety of ground handling services at airports. This includes fueling, hangaring, tie-down and parking, and flight planning assistance, among other services that support the operations of general aviation. A well-equipped FBO acts as a hub for pilots and their passengers, offering essential services that facilitate safe and efficient operations at the airport.

While flight training services, air traffic regulation, and safety inspections are important aspects of aviation, they fall under different organizations or operational roles. Flight training is typically provided by specialized schools or instructors rather than an FBO. Air traffic regulation is handled by air traffic control authorities, not by FBOs. Inspections for safety compliance are performed by certified aviation inspectors or maintenance organizations, distinct from the primary functions of an FBO. Thus, the core function of an FBO revolves around ground operations, making that choice the best descriptor of its role.
