MissedApproachVerfahrens

Missed approach is a predefined course of action in aviation used to abort a landing when the aircraft cannot land safely. It is triggered when the required visual references or instrument indications are not established by the published missed approach point or the designated decision altitude or height. The term applies to both instrument approaches and certain visual approaches, and it is distinct from a go-around that may be performed at any point during the approach.

Instrument approaches include a published missed approach procedure that specifies the initial climb, heading, and altitude, as well as the subsequent routing to a holding fix or to rejoin another approach. The procedure is part of the instrument approach chart and is designed to provide a safe transition from the approach phase to a subsequent phase of flight, such as holding or re-entry into an approach.

Execution involves applying power, configuring the aircraft for climb, and following the published path or ATC instructions. The pilot ensures a safe climb gradient, maintains obstacle clearance, and communicates with air traffic control as required. The aircraft typically climbs to a published initial missed approach altitude and proceeds along the prescribed route, which may include headings, legs, or a hold.

The missed approach point for non-precision approaches is defined by distance or fix on the final approach, while precision approaches use a decision altitude or height. If the required visual reference is not obtained by that point, the missed approach procedure is initiated. Reasons for a missed approach include deteriorating weather, insufficient visibility, an unstable approach, or other safety concerns.
