What does the term Leg represent in flight operations?

In flight operations, the term "Leg" refers to a portion of a flight route or segment. Each leg of a flight represents the distance traveled between two points, typically between two airports, or between two waypoints in the air. This means that a flight can consist of multiple legs, depending on the planned itinerary. For instance, a direct flight from one city to another is a single leg, while a journey that includes layovers at various airports will have multiple legs, each connecting different portions of the route.

Understanding the concept of a leg is crucial for flight planning, scheduling, and operational management, as it helps in organizing the journey and assessing the time and distance involved for each specific segment of the flight. The other options provided do not accurately represent this terminology in the context of flight operations.
