FAA Ground School Practice Test

The pilot in command holds the final authority over the operation of an aircraft because this individual has the ultimate responsibility for the safety and operation of the flight. The role of the pilot in command encompasses not only making decisions regarding the flight itself, including route adjustments and responding to in-flight emergencies, but also ensuring that the aircraft is operated in compliance with all regulations and company policies.

This authority is anchored in aviation regulations, which recognize the pilot in command as the key decision-maker when it comes to the safe handling of the aircraft. While other officials, such as air traffic controllers or ground personnel, provide necessary support and guidance, they do not hold operational authority over the flight. Similarly, although the aircraft owner may have an interest in how the aircraft is operated, they do not have the same level of authority as the pilot in command, who is trained and certified to make the critical decisions that arise during the flight.
