What is a Runway excursion ? 

Runway Excursion is the event in which an aircraft veers off or overruns the runway surface during either takeoff or landing.

One of the world's most common reported event can end up either being an incident or a fatal accident.

What are different types of Runway Excursions ? 

There are four types of runway excursions:

'Takeoff veeroff', 'Takeoff overrun'; 'Landing veeroff' & 'Landing overrun' out of which, Landing overruns & veeroffs are among the majority.

What are the common contributing Factors ?

The Major factors Responsible for these excursion can be seen as :

Landing Overrun Factors:
Wet/Contaminated runway
Tailwind
Long landing or Incorrect decision to land
Speed too high
Late/incorrect use of brakes & reverse thrust.
Aquaplaning
Too high on approach
Landing veeroff factors -:
Crosswind
Wet/ contaminated runways
Nosewheel steering issues
Hard landing
Landing gears collapse
Tire failure
Asymmetric power

Takeoff overrun factors -:
Wet or contaminated runway
Abort / Reject after V1
Tire failure
Takeoff mass too high / incorrect

Takeoff Veeroff Factors:
●Crosswind
●wet/Contaminated runway
●Nosewheel steering issues
●Asymmetric power
