The PFD displays A/T engage status, operating mode and faults. All A/T faults are annunciated on EICAS.
The dual Electronic Thrust Trim System (ETTS) provides limited authority thrust trimming, over the full flight regime, via electronic trim commands to the FADEC.
The ETTS provides EPR trim, N1 synchronization, N2 synchronization, engage status as well as fault annunciation on EICAS.
GF1810_043
The A/T . ETTS system contains the following :
.  
AT/ETTS software which co-resides and co-executes with the FMS software, on the processor of the FMS card, in Integrated Avionics Computers’ (IACs) #1 and #2.

.  
Interface with the Throttle Quadrant Assembly (TQA).

.  
Interface with both FADECs (output via Fault Warning Computers (FWC), input via Data Acquisition Units’ (DAUs) #1 and #2 for the left and DAUs #3 and #4 for the right engine).

.  
Two servos located in the TQA.

.  
Two engage/disengage switches and two quick disconnect switches, located on the thrust levers.

.  
An A/T source selection on the MFD menu.

.  
An EPR rating and a EPR CMD/N1/N2 SYNC selection on the FMS menu.

POWER PLANT
 
Autothrottle Data Sources
The A/T system is compatible with the active pitch mode, as determined by the AFCS or FMS. Thrust control is maintained when speed is controlled via pitch control.
The A/T uses sensor data from the coupled PFD, to ensure consistent and compatible operation with the AFCS. Data received from the AFCS and FMS is selected from the active AFCS and FMS to ensure A/T control is compatible with the pitch control.
The A/T selects the ADC displayed on the coupled PFD as the ADC source during non-dual coupled Autopilot/Flight Director (AP/FD) operation. During dual coupled AP/FD operation, the A/T selects the ADC displayed on each PFD and averages the data.
The A/T selects the IRS displayed on the coupled PFD as IRS source during non-dual coupled AP/FD operation. During dual coupled AP/FD operation, the A/T selects the IRS displayed on each PFD and averages the data.
The A/T selects the coupled side PFD during single coupled AP/FD operation. During dual coupled AP/FD operation the A/T continues to use the PFD it was using prior to coupled operation.
The A/T selects and uses status information and data from the active AFCS and the active FMS.
The A/T identifies the active DAU channel via data received from the Fault Warning Computer (FWC).
The A/T indicates the DAU selected source for the FADEC data and uses status information and data from the FWC. The FWC monitors the channel in control status, to assess FADEC integrity.
The A/T identifies the active radio altimeter via selection data received from the FWC. The radio altimeter data is obtained via the EFIS.
