What occurs during a takeoff overrun?

During a takeoff overrun, the primary occurrence is that the aircraft exits the end of the runway. This situation typically arises when the aircraft fails to reach a sufficient speed for takeoff or does not gain appropriate altitude and is unable to stop before reaching the end of the runway. This can be due to a variety of factors, including a wet or contaminated runway, insufficient runway length, or improper thrust application.

The safety protocols surrounding takeoff procedures are designed to help prevent overruns, which can lead to significant risks, including damage to the aircraft and potential injury to the occupants. Proper understanding of aircraft performance, including takeoff distances and runway conditions, is crucial for pilots to help mitigate the risk of an overrun.

In contrast, the completion of a takeoff suggests a successful and safe ascent, which does not align with the definition of a takeoff overrun. An engine failure would likely occur during the takeoff roll or climb and does not specifically denote an overrun event, while a stall, which usually occurs at low airspeeds during flight, is not relevant to the takeoff phase when determining an overrun scenario.
