G1000 System Maintenance Manual

NOTE
Configuration mode contains certain pages and settings that are critical to
aircraft operation and safety. These pages are protected and cannot be
modified. However, most protected pages are viewable to allow system
awareness for troubleshooting.
Using the FMS knob on PFD1 turn to the GRS page group. Use the B ALT field for all CFR
Part 43 Appendix E tests for G1000 altitude.
4.
Place the MFD in Reversionary mode by pressing the red “display backup” button on the
GMA 1347D Audio Panel #1. The baro setting can then be read from the MFD for CFR Part
43 Appendix E tests.
NOTE
The baro setting on the MFD is controlled by PFD1. The baro setting will
apply to both GDC 74B #1 and GDC 74B #2 regardless of the GDC 74B
selected on the MFD. The copilot’s display can be ignored.
After completing the tests specified by § 91.411 and Part 43 Appendix E, return both the MFD
and PFD1 to normal mode.
NOTE
The following tests are above and beyond the requirements set forth in
Appendix E, and are required only when appendix E tests are required.
Pitot/Static Airspeed Test
1.
Command air data test set (ADTS) to simulate air speeds shown in the table below.
2.
Wait for ADTS to report that target values have been achieved.
3.
Verify that computed air speeds shown on the PFD are within the tolerances specified in the
OEM maintenance documentation.
Static Port Vertical Speed (Rate of Climb) Test
1.
Command ADTS to change the altitude at the rates shown in the table below.
2.
Wait for ADTS to report that target rates have been achieved.
3.
Verify that the Rate of Climb reported by the Vertical Speed field on the PFD is within the
tolerances specified in the table below:
Vertical Speed, feet/minute
Allowed tolerance, ±feet/minute
2000 100
0 45
-2000 100
