The Runway Excursion category includes also two types of occurrences which do not fit the ICAO ADREP definition for a runway excursion, however considered appropriate for inclusion due to the commonality of a number of causal and contributory factors and/or mitigation approaches:
- An aircraft attempting a landing touches down in the undershoot area of the designated landing runway within the aerodrome perimeter.
- A runway or taxiway other than the designated one is used for a take off or a landing.
The European Commercial Aviation Safety Team (ECAST) in the European Strategic Safety Initiative (ESSI) use the Skybrary definition when writing about Runway Excursion Prevention
Articles within the Runway Excursion Category in SKYbrary:
- Overrun on Take Off
- Overrun on Landing
- Directional Control
- Undershoot on Landing
- Wrong Runway

in the ICAO definition, the B777 undershoot at Heathrow
would not be a RE, but with the Skybrary definition it would be.
Dear Safety Managers of the world, there still is a lot of work to
