1.31.2 Integrated Standby Instrument - Piston
Aircraft
An integrated standby instrument configuration consists of two GDU 700Ps, each
with separate AHRS/ADC sensors. One display serves as the PFD, the other as EIS,
MFD, or MFD/EIS. When activated, the display backup switch forces both displays
into their display backup mode of operation.
The GBB 54 backup battery provides power to the PFD and sensors in the event of
primary aircraft power failure. Both displays monitor and compare independent
attitude, altitude, and airspeed data. The EIS, MFD, or MFD/EIS automatically displays
its backup primary flight information when:
1. Either display detects a miscompare between attitude, altitude, or airspeed
parameters.
2. Communication between displays is lost.
3. The display backup toggle switch is active.
This configuration provides the following functionality, which satisfies the backup
instrumentation requirements.
The MFD, EIS, or MFD/EIS behaves as follows:
•
An MFD will transition to a full-screen PFD display
•
An EIS will transition to a split-screen PFD/EIS display
•
An MFD/EIS will transition to a split-screen PFD/EIS display
