What is a Runway excursion?

What is a Runway excursion ? What are different types of Runway Excursions ? What are the common contributing Factors ?

✔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.

✔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.

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 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
