8. The F-ACK button can be used as a fault recall to re-evaluate the
problem that has not cleared. Pressing the F-ACK again the PFL will
display the image on the left. Subsequent presses will display page 2
and page 3 if still present. The way faults happen is very dynamic and
in this case there is no page 3 as some of the initial faults were normal
faults happening during the ramp start procedure.
9. Reviewing those faults the pilot now finally realises that the AIR
SOURCE knob is not in the NORM position. He moves the knob
accordingly. The FLCS status light will disappear as the FLCS faults
clear.
10. The AV mnemonic will remain on. A further fault recall (pressing
the F-ACK button) will show the pilot that the MMC is still degraded.
Shutting down the MMC power may or may not clear the fault. The
active cooling may or may not provide enough bleed-air to cool down
the MMC and make it operational again, depending on how long the
system was overheated.
3.4.2.2. Special considerations:
•
The PFLD is powered by the UFC and will obviously blank if no power is available to the UFC
or in case of UFC failure. In that case the AVIONICS FAULT caution light is disabled as well.
•
If the FLCS system fails (FLCS BUS FAIL) the AVIONICS FAULT caution light will illuminate
rather than the FLCS FAULT light. FLCS faults are not reported on the PFLD and the MFD
FLCS page will report OFF. The only way to see the fault is through the MFD TEST page.
•
ELEC faults must be acknowledged with the ELEC CAUTION RESET pushbutton on the
ELEC panel (left console).
•
It is normal to have to press the F-ACK button numerous times to clear and/or review faults.
