procedure, perform Section 3.8.
PFD/MFD Test
1. Allow displays to initialize for ~1 minute.
2. Check that all COM/NAV display fields are valid in the top corners of both PFDs.
3. Check that attitude, heading, altitude, airspeed, vertical speed and OAT fields are valid
within 2 minutes of power up on both PFDs.
4. Press the Sensor softkey on each PFD and switch between ADC1 and ADC2. Verify
that data from both GDC air data computers is valid on both displays.
5. Press the Sensor softkey on each PFD and switch between AHRS1 and AHRS2. Verify
that data from both GSU 75 or GRS 77/7800 is valid on both displays.
6. Check that the engine instrument fields are valid on the MFD.
7. Push the red DISPLAY BACKUP button on the pilot-side GMA 1347D. Verify that the
pilot-side PFD and MFD displays enter reversion mode. MFD should have valid altitude,
airspeed, vertical speed, COM1, COM2, NAV1, NAV2 and engine instruments.
8. De-activate pilot-side reversion mode by pushing the DISPLAY BACKUP button. Verify
PFD 1 and MFD return to normal display modes.
9. Repeat Step 1 using GMA2. Ensure that PFD 2 and MFD enter reversion mode and
MFD displays valid altitude, airspeed, vertical speed, COM1, COM2, NAV1, NAV2 and
engine instruments.
10. De-activate co-pilot's side reversion mode by pushing the DISPLAY BACKUP button.
Verify PFD 2 and MFD return to normal display modes.
11. Select the Map – TAWS Map page on the MFD.

TAWS has not been enabled, the title will read "Map – Terrain Proximity" or "Map –
Terrain".
13. Press the MENU button and select "Test TAWS" from the pop-up menu.
