What is a Runway Excursion?
A runway excursion (RE) is a veer off or overrun from the runway surface (ICAO). These surface events occur while an aircraft is taking off or landing, and involve many factors ranging from unstable approaches to the condition of the runway. It is important that all parties involved (Pilots, Air Traffic Controllers, Airport Authorities, etc.) work together to mitigate the hazards that result in an RE. The FAA Runway Safety program is committed to reducing RE risk through analysis, awareness, and action.
The following web sites provide useful information and help provide a foundation to understanding REs and the factors that contribute to them.
