AIRSPEED MISCOMPARE
This message is displayed when the G1000 detects a difference of 7 KIAS or greater between the
pilot’s and copilot’s airspeed indicators (10 KIAS difference during takeoff or landing roll). Refer to
the G1000 Cockpit Reference Guide for additional information.
1. Pilot’s and Copilot’s Airspeed .....................................COMPARE with Standby Airspeed Indicator.
THE STANDBY AIRSPEED INDICATOR USES THE SAME PITOT-STATIC SOURCES AS THE
COPILOT’S SIDE AIR DATA COMPUTER (ADC2). DO NOT USE STANDBY AIRSPEED
INDICATOR OR STANDBY ALTIMETER AS SOLE SOURCE IN DETERMINING CORRECT
AIR DATA INFORMATION.
¾ IF PILOT PFD AND STANDBY AIRSPEED INDICATOR AGREE (COPILOT PFD DIFFERS)
2. SENSOR Softkey (Copilot’s PFD) .........................................................................................PRESS
3. ADC1 Softkey.........................................................................................................................PRESS
4. PFD Displays .......................... CONFIRM
annunciator is displayed on both PFDs.
¾ IF COPILOT PFD AND STANDBY AIRSPEED INDICATOR AGREE (PILOT PFD DIFFERS)
2. Pilot and Copilot ALTITUDE ....................................................................................................NOTE
 IF PILOT’S AND COPILOT’S ALTITUDE AGREE
3. Airspeed 120 KIAS MINIMUM on slowest indicator
4. Monitor all three airspeed indicators during changes in power or altitude to determine which
indicators are inaccurate. Indications of inaccurate airspeed include:
• No change in indicated airspeed when power change and altitude maintained.
• Indicated airspeed increases when climbing or decreases when descending.
5. Use SENSOR softkey to select most accurate ADC on the affected PFDs
6. Airspeed ............................................................................................. RESUME NORMAL SPEEDS
 IF PILOT’S AND COPILOT’S ALTITUDE DO NOT AGREE
3. Refer to Abnormal Procedures, ALT MISCOMP procedure to determine most accurate ADC.
PITCH MISCOMPARE
This message is displayed when the G1000 detects a difference between the pilot’s and copilot’s
pitch attitude (displayed in the upper right of the PFD). Refer to GARMIN G1000 Cockpit
