Threat and Error Management (TEM) is a concept used in aviation safety to proactively identify and manage potential threats or errors that can occur during a flight. It involves recognizing threats, errors, and undesired aircraft states to prevent accidents or incidents.

In the context of preventing a runway excursion after touchdown, it is imperative for flight crews to consistently maintain a stabilized approach during the final phases of landing. This entails strict adherence to predetermined criteria governing airspeed, descent rate, and runway alignment. In the event that an approach becomes destabilized, thereby elevating the risk of a runway excursion, it is incumbent upon pilots to promptly implement corrective measures to restore stability before the landing occurs. This ensures a safe and controlled touchdown and subsequent rollout on the runway.

If the approach is not stable by 1 000 feet AGL or 500 feet AGL (depending on weather conditions), or if the approach becomes unstable below these altitudes, the pilot should initiate a missed approach/go around.
