Prevention of EGT Overlimit Events
A number of engine Exhaust Gas Temperature (EGT) overlimit events at takeoff were reported to Airbus, including dual events leading to a significant increase in flight crew workload at low altitude. This article recalls the importance of monitoring the EGT margin of each engine to detect any degradation in engine performance early, and provides recommendations to Maintenance, Flight Operations, and flight crews to prevent EGT overlimit events. It also reminds us of what to do in the case of an EGT overlimit indication at takeoff.
Unreliable airspeed at Takeoff
Since the beginning of 2020, Airbus has received an increasing number of reports of unreliable airspeed events at takeoff due to Pitot probe obstruction. Despite the existing prevention means and the preflight exterior walkaround, takeoffs with obstructed air data probes may happen. This article highlights why it is so important for pilots to actively monitor the airspeed during the entire takeoff roll, to detect an airspeed discrepancy as early as possible, and safely reject the takeoff, if required to do so.
Takeoff Surveillance & Monitoring Functions
Airbus has continuously improved takeoff safety since the “TO CONFIG TEST” pushbutton was first introduced on A300 and A310 aircraft, and with the development of the Takeoff Surveillance (TOS1 & TOS2) and Takeoff Monitoring (TOM) functions.The TOS2 package that was initially developed for the A350 is now available for A320 family and A330 aircraft. This is an opportunity to review the checks that are performed by each function, from cockpit preparation to takeoff.
Control your speed… at take-off
One of the most critical decisions that every line pilot may potentially encounter during every take-off is to continue or abort the procedure; hence the essential need to properly monitor the airspeed during this phase.
