- One of the world's most commonly reported events can end up either being an incident or a fatal accident.
- There are four types of runway excursions: 'Takeoff veer off, 'Takeoff overrun'; 'Landing veeroff' & 'Landing overrun' out of which, Landing overruns & veer offs are among the majority.
The Major factors Responsible for this 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 runway
- Nose wheel steering issues
- Hard landing
- Landing gear collapse
- Tire failure
- Asymmetric power
Takeoff Overrun Factors:
- Wet/Contaminated runway
- Abort/reject - After V1
- Tire failure
- Takeoff mass too high/incorrect
Takeoff Veeroff Factors:
- Crosswind
- Wet/Contaminated runway
- Nose wheel steering issues
- Asymmetric power
