How far does RESA extend from runway strips?

How far does RESA extend from runway strips?

• A. 50 ft.
• B. 100 ft.
• C. 300 ft.
• D. 500 ft.

Answer: (C)

RESA, or Runway End Safety Area, is the buffer beyond the end of a runway that gives an aircraft space to decelerate if it overruns. The standard minimum extension is 300 feet. That distance provides enough room for deceleration and to keep the airplane clear of obstacles on the far end, reducing risk to people and equipment on the ground. Shorter buffers wouldn’t reliably absorb the energy of an overrun, while longer buffers aren’t usually required unless a specific risk assessment calls for it.
