7.6.1 GDC Testing
Allow the unit to warm up for 15 minutes before performing the following tests.
Verification of the altimeter and airspeed must be performed using an air data test set (ADTS).
The static port and altimeter must be verified in accordance with Title 14 of the Code of Federal
Regulations (CFR) § 91.411 and Part 43 Appendix E. The PFD must be in Configuration mode
and the MFD must be in Reversionary mode for performing the tests as outlined in Part 43
Appendix E.
To prepare the G1000 System for Part 43 Appendix E testing:
Configuration mode contains certain pages and settings that are critical to aircraft
operation and safety. These pages are protected and cannot be modified, unless
the technician is properly authorized and equipped. However, most protected
pages are viewable to allow system awareness for troubleshooting.
1. Start the G1000 system in normal mode.
2. Remove power to PFD1.
3. Turn PFD1 on in Configuration mode by pressing and holding the ENT key on the PFD while
applying power.
4. Release the ENT key after "INITIALIZING SYSTEM" appears in the upper left corner of the
PFD.
Configuration mode contains certain pages and settings that are critical to

5. Using the FMS knob on the PFD turn to the GRS page group. Use the B ALT field for all
CFR Part 43 Appendix E tests for G1000 altitude.
6. Place the MFD in Reversionary mode by pressing the red "display backup" button on the
GMA. The baro setting can then be read from the MFD for CFR Part 43 Appendix E tests.
