What is a Runway Blast Pad?

As we all know an aircraft leaves the runway after taking-off at an angle close to 3 degrees. Due to this angle of the aircraft, a strong jet blast from the engines can erode the surface just after the runway.

Soil, gravel and other particles on the ground is thrown in to the runway by the strong jet blast. This introduction of foreign matters to the runway can endanger the safety of aircraft that use the runway either for  take-off or landing.

An unprecedented Foreign Object Damage (FOD) during the most critical phase of the flight will be a nightmare for a pilot and should implement all measures to preclude such damages.

Runway Blast Pads were introduced just after the end of the runway threshold to eliminate Foreign Object Damages.

They are not robust as the runway surface and pilots are not permitted to land or taxi in this area unless during an aborted take-off or runway over-run in a landing.

Blast Pads are marked with yellow color chevrons. They are also named as runway Overrun areas or Stopways in some applications.
