Hi Microburst2002,

ENG 1(2) THR LEVER FAULT.
"For any case of thrust lever fault (TO, FLEX or between IDLE and MCT) the FADECwill command idle thrust for the approach when slats are extended (or when MN < 0.47 if associated EIU is failed). It is independant of the autothrust condition. Thrust of affected engine remains definitively at idle even for go around and the reminder of the flight."
I've tried it in the sim and thrust remained at idle even when clean.
