- A runway or taxiway other than the designated one is used for a take off or a landing.

I en artikel "Språk- och säkerhetsproblem" i Eurocontrols tidningen 2011 skrev Bert Ruitenberg:
The whole idea of putting a label such as “runway incursion” or “runway excursion” on a safety occurrence is to make it easier to file the data from the event somewhere and to compare it with similar occurrences. With the definitions above, a take off from a taxiway would be considered as a Runway Excursion when the Skybrary definition is used, but not with the other RE definitions (and rightly so, I say, better label it a “taxiway take off”). Moreover, 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 be done...
