What is the basic runway length known as?

• A. Takeoff Run Available (TORA)
• B. Landing Distance Available (LDA)
• C. Runway Safety Area (RSA)
• D. Ground Roll Distance

Answer: (A)

The basic runway length is referred to as Takeoff Run Available (TORA). TORA is a critical parameter in aviation, representing the length of runway that is available for the takeoff run of an aircraft. This measurement is essential for pilots and flight planners as it directly affects the performance calculations for aircraft during takeoff, ensuring that there is adequate distance to reach takeoff speed safely. TORA does not account for any additional distances that may be available for takeoff, such as the distance needed for the takeoff climb or obstacles. It represents the actual physical length of the runway that is usable for the purpose of taking off. Understanding TORA helps ensure that aircraft operate within safe performance limits, minimizing the risk of accidents during the critical takeoff phase. In contrast, the other options refer to different but related concepts within airport operations and runway management. For instance, Landing Distance Available (LDA) applies to the distance available for landing, while Runway Safety Area (RSA) pertains to the area surrounding the runway that enhances safety by minimizing risks to aircraft operations. Ground Roll Distance relates to the distance an aircraft travels on the runway during the takeoff or landing phases, but this does not represent the total usable length of the runway.
