What does the term "route of flight" refer to?

The term "route of flight" specifically refers to the planned flight path from one airport to another. This encompasses the intended trajectory that an aircraft will follow, which is determined prior to departure. The route of flight includes various waypoints, airways, and navigational aids that the aircraft will utilize to navigate safely and efficiently to its destination.

This planned route is crucial for operational purposes as it helps in managing air traffic, optimizing fuel usage, and ensuring adherence to regulations and airspace restrictions. Thus, the route of flight is foundational to flight planning and operational control.

While altitude, air traffic control instructions, and course corrections are important elements of flight operations, they do not encapsulate the broader concept of the route of flight, which is primarily concerned with the overall planned journey from one location to another.
