A veer off or overrun off the runway surface. (ICAO)
This SKYbrary category includes two types of occurrences, notably "Undershoot on Landing" and "Wrong Runway Use", which do not fit the ICAO ADREP definition for a runway excursion. However, their inclusion has been considered appropriate due to the commonality of a number of causal and contributory factors and/or mitigation approaches.
