DEFINITION
A runway excursion occurs when an aircraft accidentally departs the runway in use during takeoff or landing procedure. A veer off could happen through the sides or end of the runway.
SCENARIOS
- A departing aircraft can’t become airborne or reject the takeoff over the runway.
- A landing aircraft is unable to stop over the runway’s length.
- An aircraft taking off, rejecting takeoff or landing veers off the runway. - A pilot incorrectly steers the aircraft.
MITIGATION
- Accurate and timely reporting of ambient conditions by ATC, especially wind direction, variation and runway conditions. Precise communication. - Good Flight planning. - Correct handling techniques.
- Effective decision making and technique for rejecting a landing soon after initial touchdown or for rejecting a takeoff from a speed close to or of V1.
EXCURSION VS OVERRUN
A runway excursion is a veer-off from the runway’s surface. A runway overrun happens when the aircraft fails to stop within the runway limits and overshoots the opposite threshold.
