Definition
A missed approach procedure flown with one engine inoperative, used by multi-engine aircraft when a landing cannot be completed and one engine has failed. Because climb performance is significantly reduced on a single engine, the aircraft may be unable to meet the climb gradient required by a standard published missed approach, so operators must pre-plan an alternative procedure or ensure the published missed approach can be flown safely with one engine out.
Plain English
It is the go-around plan for a multi-engine aircraft that has lost one engine. With less power available, the aircraft cannot always climb as steeply as the published missed approach requires, so the crew needs a procedure they know they can actually fly.
Context Anchor
Seen in instrument approach planning, performance calculations, simulator training, and multi-engine operations where the pilot must consider whether the airplane can climb after an engine failure near the runway.
Why Pilots Care
Failure to account for reduced climb performance can result in terrain or obstacle contact during the go-around.
Grounding Statement
Picture being close to the runway, unable to land, and then having to climb away with only part of the airplane’s normal power available.
Intuition Check
“Missed” does not mean the pilot made a mistake. In this term, a missed approach means the landing is not continued and the airplane must climb away using the required procedure.
Example Sentence 1
Before starting the approach into the mountainous airport, the crew briefed an engine-out missed approach that turned away from the high terrain rather than following the published procedure.
Example Sentence 2
Before starting the approach, the crew confirmed the aircraft could meet the engine-out missed approach climb gradient published for the runway.
