Airbus recently performed some research on the quality of go-around execution. This involved examining nearly 500,000 approaches flown by many airlines from around the world.The results highlighted that in some cases crews are choosing not to apply the Airbus Standard Operating Procedure (SOP) for the go-around phase.Particularly when a go-around was performed above 1,200 ft, the flight crew often decided to adapt the engines thrust selection instead of setting TOGA thrust. Feedback from operators also indicates a similar tendency. As a result, Airbus received several reports of unexpected aircraft trajectories and energy management techniques during the go-around procedure.Therefore, it was decided to address these issues by:Better defining an optional thrust levers management tech-nique during the a go-around, as per Airbus SOP.Developing a “Discontinued Approach” technique that wouldallow crews to effectively “abort” the approach without selecting TOGA detent.The Flight Crew Training Manual (FCTM) and the Flight Crew Operating Manual (FCOM) were updated accordingly end 2013 (updates respectively in March and May 2014 for the A300/A310 and A380).
