05 - TRAINEES’ ACTIONS
DISAGREE
This failure occurs when the two validated thrust lever angle signals are not in agreement.
Should the failure occur on take-off, TOGA or FLEX thrust is maintained until thrust
reduction, after which maximum available thrust is MCT.
If the failure occurs when the thrust lever is between idle and MCT, FADEC will automatically
select the larger thrust lever angle, limited to MCT. On the ground, thrust is limited to idle.
In flight, keep the A/THR engaged (or engage A/THR if not in use) to allow it to manage
thrust between idle and the larger thrust lever angle position.
The FADEC will automatically set the thrust of the affected engine to idle when CONF 1 is
selected.
Note that reverse thrust is available for landing.
FAULT
If this fault develops, it indicates that a non-valid signal has been received from engine 1 or 2 thrust lever angle.
The fault on the ground freezes thrust to idle, and furthermore commands the reversers to stow.
In flight, keep the A/THR engaged (or engage A/THR if not in use) to allow it to manage thrust between idle and the larger thrust lever angle position. A/THR should be engaged before slat retraction. The FADEC will automatically set the thrust of the affected engine to idle when CONF 1 is selected.
Note that reverse thrust is NOT available for landing.
06 - COMPLETION STANDARDS

Respects task sharing procedures and ensures good crew communications.
07 - COMMON ERRORS
.
Different reason for "Disagree" and "Fault" not clearly understood.
.
Specific procedure not applied for approach.
