The is a masterpiece of human-factors engineering. It acknowledges that during a go-around, a pilot’s cognitive load is maxed out. By leveraging the "pull for managed" philosophy, the Airbus transforms a high-risk maneuver into a standardized, safe, and repeatable process.

The energy pumping works. N2 crosses 15%, fuel is injected, and a glorious "bang" signals engine light-off. You recover, declare an emergency, and land. This has happened twice in A320 history (both due to total fuel starvation followed by successful windmill restarts using the Sierra principle). sierra pattern a320
