Unstabilized approach
An unstabilized approach is an approach during which an aircraft does not maintain at least one of the following variables stable: speed, descent rate, vertical/lateral flight path and in landing configuration, or receive a landing clearance by a certain altitude. Unstabilized approaches account for most approach and landing accidents. For this reason, an approach should be stabilized by above runway altitude. Otherwise, a go-around should be executed by the pilot.
For example, the 2016 Magdalen Islands Mitsubishi MU-2 crash was blamed on an unstabilized approach.
