HEADING MISCOMPARE
This message is displayed in the upper right corner of the PFD when the G1000 detects a
difference between the pilot’s and copilot’s heading information. Refer to the GARMIN G1000
Cockpit Reference Guide for additional information.
1. WSHLD ANTI-ICE Switches (PILOT and COPILOT) ................................................................. OFF
2. CABIN TEMP MODE selector ..................................................................................................... OFF
3. ELEC HEAT ................................................................................................................................ OFF
4. Refer to Magnetic Compass to determine which AHRS is providing the most accurate heading
information.
5. Use SENSOR softkey to select the most accurate AHRS on the affected PFD.
6. WSHLD ANTI-ICE Switches ..................................................................................... AS REQUIRED
7. CABIN TEMP MODE ................................................................................................... AS DESIRED
8. ELEC HEAT .............................................................................................................. AS REQUIRED
NOTE
The magnetic compass is affected by windshield anti-ice and/or air conditioner operation.
These items must be turned OFF prior to referencing magnetic compass heading, and then
may be reselected ON. With windshield anti-ice OFF, fog or frost may form on the inside
surface of the windshield. The windshield anti-ice should be turned off only long enough to
reference magnetic compass or the pilot should descend to a warmer altitude if terrain, fuel,
and endurance permit.
LOSS OF ALTITUDE REPORTING IN RVSM AIRSPACE
If ATC is not receiving altitude reporting information while in RVSM airspace:
1. XPDR Softkey ............................................................................ SELECT OTHER TRANSPONDER
2. Verify selected transponder is in ALT mode.
LOSS OF ALTITUDE ERROR CORRECTION
Loss of altitude (static source) error correction in the air data computers is indicated by an advisory
message in the alerts window of the PFD. The static source error correction is effective only above
18,000 feet MSL. The following advisory messages will post:
ADC1 ALT EC - ADC1 altitude error correction is unavailable.
and/or
ADC2 ALT EC - ADC2 altitude error correction is unavailable.
