What does TORA stand for in aviation terminology?

TORA stands for Takeoff Run Available in aviation terminology. It is a key measurement used in runway performance calculations, indicating the length of runway that is available for an aircraft to execute its takeoff. This measurement is crucial for pilots and flight planners as it helps determine whether the aircraft has sufficient runway length to achieve takeoff speed before reaching the end of the runway.

TORA is critical for ensuring safety during takeoff, especially in scenarios where aircraft weight, weather conditions, and runway surface can impact takeoff performance. Understanding TORA allows flight crews to make informed decisions regarding takeoff distances, ensuring compliance with operational limits for different aircraft types.

The other options relate to aviation but do not accurately define TORA, focusing instead on different aspects of runway performance or configurations that do not align with the established definition.
