What is the definition of TORA?

The definition of TORA, or Takeoff Runway Available, specifically refers to the length of runway designated for an aircraft to accelerate to the takeoff speed and become airborne. This measurement is critical for pilots and flight planners as it helps determine whether the available runway length is sufficient for a safe takeoff under various conditions, including aircraft weight and environmental factors.

Understanding TORA is essential because it impacts aircraft performance calculations. Pilots must ensure they have enough runway to reach the required takeoff speed without exceeding the available distance. As a result, TORA plays a significant role in flight safety and operational efficiency.

The others relate to runway measurements but do not specifically define TORA. Total runway length for landing encompasses the full length available for landing, while Total ground run available for takeoff refers to the entire distance an aircraft can use before becoming airborne, which is broader than just TORA. Landing Distance Available pertains to the runway space available for slowing down after touchdown. Thus, each term serves a distinct purpose within aviation operations and safety management.
