ENG 1(2) EPR MODE FAULT
Applicable to: ,
L2 The FADEC of the affected engine has automatically reverted to the N1 mode. Autothrust control is
lost.
L1CAUTION Before selection of N1 mode when in N1 UNRATED mode, THR LEVERS should
be set to a detent not higher than CLB, in order to prevent an overspeed.
On ground:
If rated N1 MODE is active:
ALL ENG N1 MODE..........................................................................................................ON
L2N1 mode is confirmed on the affected engine.
The other engine must be reverted to the rated N1 mode to ease thrust setting.
L1 If unrated N1 MODE is active:
N1 DEGRADED MODE
In flight:
ALL ENG N1 MODE.................................................................................................................ON
If rated N1 MODE is active:
MAN THR.................................................................................................................. ADJUST
L2 Refer to PER-THR-N1 N1 MODE THRUST CONTROL, for power management tables.
L1 If unrated N1 MODE is active:
N1 DEGRADED MODE
DO NOT EXCEED N1 LIMIT
L2 As there is no N1 rating limit, an overboost can occur at full forward thrust lever position.
L1MAN THR.................................................................................................................. ADJUST
L2 If the affected engine has reverted to the unrated N1 mode, align its N1 on the N1 of the
other engine, when in rated mode.
Refer to PER-THR-N1 N1 MODE THRUST CONTROL, for power management tables
when both engines are in unrated mode.
L1 If EPR mode recoverable (detected by FADEC):
L2 The ECAM caution is automatically recalled.
