T-6A Mission Ground Evaluation Practice Test

The distance available for a plane to land is known as the Landing Distance Available (LDA). This parameter is crucial for pilots to understand how much runway they have to safely land the aircraft. The LDA is measured from the landing threshold to the point where the runway is no longer usable, meaning any obstacles within this distance are accounted for, ensuring the pilot has a clear understanding of the landing capabilities regarding their specific aircraft and current conditions.

Other terms relate to different aspects of runway usage: the Takeoff Run Available (TORA) refers specifically to the length of runway available for the aircraft to take off, while the Accelerate-Stop Distance Available (ASDA) encompasses the length required to accelerate to takeoff speed and then stop if necessary. The Takeoff Distance Available (TODA) is the distance available for the aircraft to take off, which also includes additional length if there are any clear areas beyond the runway. However, none of these directly measures the distance available for landing in the same way LDA does, making LDA the correct answer.
