A veer-off is a type of runway excursion where the aircraft departs the side of the runway on takeoff or landing. This can be either unintentional (due to loss of control) or intentional (as an attempt to avoid an obstacle on the runway such as an aircraft or a vehicle).
Similarly to an overrun, a veer-off can happen on take-off as well as on landing, the difference being that in overruns the aircraft departs the runway surface at end rather than on the side.
Effects
The outcome of a veer off on landing depends mostly on the speed at the time the aircraft departs the runway surface. Depending on the circumstances, the event can result in:
