What is another name for the pilot in command?

The term "pilot in command" refers specifically to the person responsible for the operation and safety of the flight, which is commonly referred to as the captain. The captain has the ultimate authority and responsibility for the aircraft, crew, and passengers during the flight. This role includes making critical decisions regarding navigation, weather, and any in-flight issues that may arise.

In contrast, the first officer is typically the second-in-command and assists the captain, but does not have the same level of authority. The flight engineer, if present, is responsible for monitoring and managing aircraft systems, while the navigator focuses on the aircraft's route and positioning, but neither holds the same commanding authority as the captain. Thus, the captain is the correct term for the pilot in command due to their overarching responsibility and leadership during the flight.
