4.11 Engine Data Check (GIA 1 or GIA 2 Inoperative)
NOTE
This procedure should be accomplished in conjunction with the engine run-up. Valid
engine indications will be needed.
Do the following to verify the engine data availability and validity, with GIA 1 or GIA 2 inoperative:
1. Ensure the G1000 is in normal mode.
2. With engines running, note the indication values for torque, ITT and oil pressure.
3. On the right hand circuit breaker panel, open the GIA1 (PRI) and GIA1 (SEC) circuit breakers.
4. Verify the values for torque, ITT and oil pressure remain unchanged.
5. Close the GIA1 (PRI) and GIA1 (SEC) circuit breakers and wait until the COM1 and NAV1 fields
are valid.
6. Open the GIA2 circuit breaker.
7. Verify the values for torque, ITT and oil pressure remain unchanged.
8. Close the GIA2 circuit breaker and wait until the COM2 and NAV2 fields are valid.
9. Put the G1000 in Reversionary mode.
10. Repeat steps 2 through 8, verifying engine gauge indications on PFD 1, MFD and PFD 2.
11. The Engine Data Check is complete.
4.12 Trim Annunciator Check
This procedure checks the pitch trim ( PTRM ) annunciation from both GIA 1 and GIA 2 and the mis-trim
AFCS status alerts.
1. Ensure the G1000 is in normal mode, autopilot is not engaged, and the mode controller XFR key is
selected to the pilot side.
2. Press the left part of the pilot’s pitch-trim switch upwards for approximately 10 seconds and verify
that the red
PTRM annunciation is displayed on both PFD 1 and PFD 2.
3. Release the switch and wait for the PTRM annunciation to clear.
4. Press the left part of the pilot’s pitch-trim switch downwards for approximately 10 seconds and verify
that the red
PTRM annunciation is displayed on both PFD 1 and PFD 2.
5. Release the switch and wait for the PTRM annunciation to clear.
6. Repeat Steps 2 through 5 for the right part of the pilot’s pitch-trim switch.
7. Repeat Steps 2 through 6 for the copilot’s pitch-trim switch.
8. Select copilot side by pressing the XFR key on the mode controller (changes active GIA to GIA 2).
9. Repeat Steps 2 through 7 and verify annunciations are displayed on both PFD 1 and PFD 2.
10. Re-select pilot side by pressing XFR key on the mode controller (changes active GIA back to GIA 1).
11. Hold the control yoke in the center position and center the pitch trim wheel.
12. Press the Go Around button on the throttle and engage the autopilot. Apply a forward load on the
control yoke. Verify that the pitch trim wheel rotates in the UP direction.
