A330 eng1(2) thr lever fault

[1jumbo]

Assuming EIVMU available and failure on descent. With ATHR engaged expect thrust to idle with slats extended or gear down. As engine runs to idle, with both thrust levers still in climb detent, is it correct to assume there will be no change to ATHR FMA? (Engine is operative, but at idle thrust). Regards thrust lever management, bringing failed thrust lever to the idle position should also not generate a change to FMA either. Checking I have this correct, or have I misread FCOM and should expect a LVR ASYM indication.

you probably won’t see the ATHR FMA remain in a normal THR REF/CLB mode if the autothrust actually drives both engines to idle—the FMA normally follows what the autothrust is commanding (e.g., THR REF, THR IDLE) rather than the physical lever position — so if the system senses the engines at idle and transitions to idle logic (slats/gear down or speed/alt constraints), the FMA will show the corresponding THR IDLE indication even if the levers are still sitting in the climb gate;
