Inappropriate V/S Target during Autoflight Mode Reversion
Two cases of inappropriate V/S target during an autoflight reversion to V/S mode after a go-around were recently reported to Airbus. In both cases, the inappropriate V/S target resulted in a pitch down command of the autopilot with high thrust. The flight guidance used the previously selected V/S value set during the preceding ILS glide […]
Lightning Strikes
Each in-service aircraft is struck by lightning at least once per year, on average. Even if the level of energy of lightning strikes is high, their effects on an aircraft are limited.This article explains the lightning phenomenon and why aircraft are prone to lightning strikes. It describes how aircraft are designed to limit the effects […]
Cockpit Control Confusion
Inadvertent use of the wrong cockpit control instead of the intended control is a potential situation that pilots may encounter on any aircraft type. This kind of error can occur with even the most experienced pilots and this article explores what factors can influence and lead to this type of occurrence. The resilience of the […]

Inadvertent Autopilot Engagement during Takeoff on A220 Aircraft
Several in-service events were reported to Airbus where the flight crew inadvertently selected the autopilot while attempting to engage the autothrottle during the takeoff roll. Inadvertent autopilot engagement may result in early rotation that can lead to a tail strike, inability to climb, runway overrun, or even loss of control. The purpose of this article […]
Best Maintenance Practices for Redundant Systems
Performing similar maintenance tasks on redundant systems at the same time, or by the same person during a particular maintenance check, may lead to the repetition of a maintenance error. This creates a risk of simultaneous failure of the redundant systems when the aircraft is back into service. This article provides best practices to reduce […]
Thrust Reverser Selection is a Decision to Stop
The SOP for landing requests that the flight crew perform a full stop landing after thrust reversers selection. However, in-service flight data analysis revealed that the equivalent of one go-around per month is performed after selection of thrust reversers. This article describes an event where the flight crew performed a go-around after they had selected […]
Using Approved Tools and Ground Support Equipment for Maintenance
Special tools or Ground Support Equipment (GSE) may be required to perform some maintenance tasks. Airbus provides a list of approved suppliers for GSE or tools in the Tools and Equipment Manual (TEM). GSE or tools from suppliers that are not listed in the TEM may be offered to Operators and maintenance organizations as alternatives. […]
Non-Engagement of the Go-Around Modes in CLEAN Flaps Configuration
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 […]
