NOTE
Allow the unit to warm up for 15 minutes before performing the following tests.
3.13.1
Preperation for Air Data Validation Test
Verification of the altimeter and airspeed must be performed using an air data test set (ADTS). The pitot /
static system and altimeter must be verified in accordance with Title 14 of the Code of Federal
Regulations (CFR) § 91.411 and Part 43 Appendix E. PFD1 must be in configuration mode and the MFD
must be in Reversionary mode to perform the tests as outlined in Part 43 Appendix E.
To prepare the G1000 System for Part 43 Appendix E testing:
1. Start the G1000 system in normal mode.
2. Remove power to PFD1 by opening the PFD1 (PRI) and PFD1 (SEC) circuit breakers.
3. Start PFD1 in configuration mode by pressing and holding the PFD1 ENT key while closing PFD1
(PRI) and PFD1 (SEC) circuit breakers.
4. Release the ENT key after “INITIALIZING SYSTEM” appears in the upper left corner of PFD1.
CAUTION
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.
5. Use the FMS knob on PFD1 to select GRS page group. Use the B ALT 1 and B ALT 2 fields 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 GMA1.
The Baro setting can then be read from the MFD for the CFR Part 43 Appendix E tests. The Baro
setting on the MFD will apply to the values displayed on PFD1 in configuration mode for both
ADC1 and ADC2 regardless of the sensor selected on the MFD. The copilot's display can be
ignored.
