Which statement is NOT true regarding runway safety features?

• A. The stopway is used to stop an aircraft that aborts takeoff.
• B. The runway end safety area exists to reduce damage from undershoot or overrun.
• C. Threshold lights are green in the direction of approach.
• D. The TODA includes the length of the stopway in addition to the clearway.

Answer: (D)

Take-Off Distance Available is the distance you can use to accelerate to takeoff speed and become airborne, and it is defined as the runway length plus any clearway. It does not include the stopway. The stopway is an area beyond the runway end provided to stop an aircraft that has aborted a takeoff, and it is counted in Accelerate-Stop Distance Available, not TODA. So stating that TODA includes the stopway isn’t correct. The other statements line up with standard runway safety concepts: the stopway is indeed used to stop after an aborted takeoff, the Runway End Safety Area helps mitigate damage from undershoot or overrun, and threshold lights are green in the direction of approach.
