- LDA: Landing Distance Available

- ASDA: Accelerate Distance / Stop
Distance Available for aborted

takeoffs

Obstacle-Free Climb Area CWY

In this case, TODA 27 is extended, providing more than 35 ft of available
distance.

- TORA: Takeoff Run Available

- TODA: Takeoff Distance Available

to > 35 ft

- LDA: Landing Distance Available

- ASDA: Accelerate-Stop Distance

Available for aborted takeoffs

Stopway SWY

In this case, ASDA 27 is extended,

meaning there is a longer distance
