Backup Instruments
9.1 Display Backup
FUNCTIONAL LIMITATIONS
•
Applicable to pilot side units only
•
Only pilot or center units trigger backup mode when offline
•
Not available in single TXi display installations
•
Display backup mode supports a limited set of EIS gauges
TCAS II RAs
When a GDU 1060 is in display backup mode and providing PFD/MFD/EIS functions,
the format of the PFD narrows and the VSI is too small to depict RA bands.
To view TCAS II RAs, tap Full on the PFD to expand it to 80%.
Display backup mode
occurs under these
three conditions
•
Loss of communication with
a GDU that displays EIS or
PFD data
•
Pilot activation through
on-screen selection or toggle
switch
•
AHRS or ADC fault caused by
miscompare or missing data
(this only triggers backup
mode when the unit is
configured as a standby PFD)
When transitioning, priority is given to
primary gauges first. All menu items
and lean controls are disabled in this
mode. An optional external toggle
switch allows manual activation of
backup mode.
