What is the definition of flight path?

• A. The altitude profile of the flight.
• B. The line, course, or track along which an aircraft is flying or intended to be flown.
• C. The sequence of navigation waypoints.
• D. The fuel consumption plan for the flight.

Answer: (B)

Flight path is the actual line through three-dimensional space that an aircraft follows or is planned to follow from takeoff to landing. It encompasses both the horizontal course (where you’re going over the ground) and the vertical profile (how you change altitude). Wind and ATC instructions can cause you to adjust heading or altitude to stay on that path, so the flight path represents the true trajectory your aircraft traces over time, not just a flat map route. The idea fits best with the definition that describes the line, course, or track along which an aircraft is flying or intended to be flown.
