Air Law
Displaced Threshold
A runway can have a displaced threshold, meaning part of the runway is not
available in certain cases, but it can still be used for takeoff (but not for landing).
- TORA: Takeoff Run Available
- TODA: Takeoff Distance Available to
35 ft
- 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
available for landing.
- TORA: Takeoff Run Available
- TODA: Takeoff Distance Available to
35 ft
- LDA: Landing Distance Available
- ASDA: Accelerate-Stop Distance
Available for aborted takeoffs
