 Efforts to address runway excursion either focus on preventing runway excursions, or on minimizing the amount of damage or injury caused by a runway excursion.In the latter category, aviation safety regulators may establish standards such as minimum runway safety areas intended to allow adequate time and distance for an aircraft to stop in the event of a runway excursion.A key aspect of preventing runway excursions is providing runways of sufficient length and width to accommodate the aircraft used at an airport.
