What is defined as specified information regarding a flight?

The correct answer is flight plan because it encompasses the detailed information that pilots and air traffic control use to ensure safety and coordination during a flight. A flight plan is a formal document that outlines the intended route, estimated times for departure and arrival, altitude levels, and other operational details necessary for a successful flight. It serves as a communication tool between pilots and air traffic control, facilitating better management of airspace.

In contrast, a flight log is typically kept by the pilot to record various aspects of flight operations, including hours flown and maintenance checks, but it does not detail a flight's intended trajectory or operational procedures. A flight path refers to the actual route that an aircraft follows in the air, which may differ from the planned route due to various factors like weather conditions or air traffic. A flight profile is a more technical term that can refer to the operational study of an aircraft's performance over time, including speed and altitude changes during different phases of the flight. While all these terms relate to aviation, the flight plan is the most comprehensive term for the specified information regarding a flight.
