7.1.2.3 GDU
Testing
If the display is removed or replaced, the following checks are recommended. Start all displays
in normal mode. Press the YES softkey to acknowledge the agreement on the MFD. Allow the
displays to initialize for approximately one minute. The GRS 77 and GDC 74Bs require longer
initialization periods than do the other LRUs. During startup, this causes the attitude, airspeed,
and altitude fields to be invalid during the first ~40-60 seconds of PFD power-up.
Check the PFD1/2 and MFD displays for the following:
1.
Check that all COM/NAV display fields are valid in the top corners of both PFDs.
2.
Check that altitude, airspeed, vertical speed and OAT fields are valid on both PFDs.
3.
Check that attitude and heading are valid (unless an AHRS calibration is required).
4.
Check that the engine instrument fields are valid on the MFD.
5.
Push the red display reversion button on both GMA 1347D #1 and #2. Verify both displays
enter reversionary mode (both should have valid altitude, airspeed, vertical speed, and engine
instruments).
6.
De-activate reversionary mode by pushing the red reversion button.
