This action disengages the AP, and should be done as per design, i.e. in case of an instinctive reaction (to an AP hard over for example).
USE OF THE FD WITHOUT THE AP
When manually flying the aircraft with the FDs on, the FD bars or the FPD symbol provide lateral and vertical orders, in accordance with the active modes that the flight crew selects.
Therefore:
? Fly with a centered FD or FPD
? If not using FD orders, turn off the FD.
It is strongly recommended to turn off both FDs, to ensure that the A/THR is in SPEED mode, if the A/THR is active.
AUTOTHRUST (A/THR)
Applicable to: ALL
OBJECTIVE
The A/THR computer (within the FG) interfaces directly with the engine computer, referred to as the FADEC.
 
OPERATIONAL PHILOSOPHY
AP / FD / ATHR
 

 
The A/THR sends to the FADEC the thrust targets that are needed to:
? Obtain and maintain a target speed, when in SPEED mode
? Obtain a specific thrust setting (e.g. CLB, IDLE), when in THRUST mode.
INTERFACE
When the A/THR is active, the thrust lever position determines the maximum thrust that the A/THR can command in SPEED or THRUST mode. Therefore, with A/THR active, thrust levers act as a thrust limiter or a thrust-rating panel.
The A/THR computer does not drive back the thrust levers. The PF sets them to a specific detent on the thrust lever range.
The A/THR system provides cues that indicate the energy of the aircraft:
? Speed, acceleration, or deceleration, obtained by the speed trend vector
? N1, and N1 command on the N1 gauge (or EPR, and EPR command on the EPR gauge).
All these cues are in the flight crew’s direct line of vision.
In other words, the Thrust Lever Angle (TLA) should not be used to monitor correct A/THR
operation. Neither should the thrust lever position of a conventional autothrottle, be considered a cue because, in many hazardous situations, the thrust lever position can be misleading (e.g. engine failure, thrust lever jammed).
The TLA Determines Max Thrust for the A/THR
 
NORMAL OPERATIONS
The A/THR can only be active, when the thrust levers are between IDLE and the CLB detent. When the thrust levers are beyond the CLB detent, thrust is controlled manually to the thrust lever Angle, and the A/THR is armed (A/THR appears in blue on the FMA). This means that the A/THR
is ready to be re-activated, when the flight crew sets the thrust levers back to the CLB detent (or below).
 
OPERATIONAL PHILOSOPHY
AP / FD / ATHR
 
A/THR operating sectors all engines operating
 
AT TAKEOFF
The thrust levers are set either full forward to TOGA, or to the FLX detent. Thrust is manually controlled to the TLA, and A/THR is armed. The FMA indicates this in blue.
AFTER TAKEOFF
When the aircraft reaches THR RED ALT, the flight crew sets the thrust levers back to the CLB detent. This activates A/THR. MAX CLB will, therefore, be the maximum normal thrust setting that will be commanded by the A/THR in CLB, CRZ, DES, or APPR, as required.
