What does a 'leg' refer to in flight terminology?

In flight terminology, a 'leg' specifically refers to a flight segment from one airport to another. This concept is crucial in aviation as it helps in defining the journey made by an aircraft, breaking down the entire trip into manageable parts. Each leg represents a takeoff and landing, allowing for clarity in flight planning, scheduling, and operations. For example, a round-trip itinerary might consist of multiple legs: one from the departure airport to an intermediate stop and then another from that stop to the final destination. This terminology assists in tracking flight progress and understanding routing within the broader context of a journey.

Understanding that a leg is a segment between airports rather than other concepts like a portion of the crew, a specific number of passengers, or crew rest periods allows for a precise grasp of flight operations and enhances communication in aviation contexts.
