There were several events reported to Airbus where the go-around guidance modes did not engage when flight crews initiated a go-around. The analysis of these events indicated that the aircraft were on approach in CLEAN flaps configuration. Some of these events led to a high-energy situation toward the ground at low altitudes.
This article explains why the go-around guidance modes do not engage on some aircraft if the go-around is initiated while the aircraft is in CLEAN flaps configuration. The article provides recommendations for flight crews if they face this situation. It describes the modifications that are planned to ensure that the go-around guidance modes engage when the flight crew initiates a go-around, even if the aircraft is on approach in CLEAN flaps configuration.
