Modification Operational Impact No.151852/P12367 brought about this new software.
New FADEC Logic at Takeoff:
At takeoff, if the flight crew sets the thrust levers below or to the MCT/FLX position although the
FLEX mode is not armed (FLEX TEMP value not entered in the MCDU or FLEX TEMP value
below the Outside Air Temperature), the “ENG THR LEVERS NOT SET” ECAM caution is
triggered (“ENG FLEX TEMP NOT SET”, for aircraft neither equipped with the FWC H2F3 nor
subsequent standards). This ECAM caution requests that the flight crew set the thrust levers to
the TOGA position.
With the new ECU Software Standard 5BS, if the flight crew does not set the thrust levers to the
TOGA position, the FADEC will automatically select TOGA thrust after 8 s.
With FWC H2F5 and subsequent standards, the “ENG 1(2) STALL” ECAM caution changes.
The stall detection range is increased in high-power stall conditions.
With FWC H2F6 and subsequent standards, the new “ENG SAT ABOVE FLEX TEMP” ECAM
caution is available.
This caution appears only in flight phase 2 (between first engine start and first engine takeoff
power). This caution appears when the flexible temperature (FLEX TEMP) is below the ambient
air temperature (also referred to as Static Air Temperature (SAT)) minus 10 °C. Then, the flight
crew must check the takeoff data.
With FWC H2F6 and subsequent standards, the new “ENG 1(2) REV INHIBITED” ECAM
caution is available.
Maintenance personnel activate this caution via the interactive mode to inform the flight crew of
the inoperative status of the thrust reverser due to maintenance action.
