What term describes a flight segment between two airports?

• A. Flight
• B. Route
• C. Leg
• D. Sector

Answer: (C)

In airline terminology, the journey from one airport to another is divided into individual pieces called legs. Each leg represents the segment between two airports (or two navigation points that end at an airport), regardless of how many waypoints may be involved in between. This is the unit used for planning, fuel calculations, crew duty, and schedule accuracy, so the term leg is the precise description of that middle portion of a flight.

A flight describes the entire trip from origin to final destination. A route is the planned path the flight follows from start to finish, which can include multiple legs. A sector refers to a defined block of airspace used for ATC purposes, not to the segment between airports.
