AHRS AREAS OF OPERATION
Flight operations with the G1000 Integrated Avionics installed are prohibited north of 70° North latitude or
south of 70° South Latitude due to unsuitability of the magnetic fields near the Earth’s poles. In addition,
operations are prohibited in the following two regions:
North of 65° North latitude between longitude 75° W and 120° W (Northern Canada).
South of 55° South latitude between longitude 120° E and 165° E (region south of Australia and New
Zealand).
NOTE
The Garmin G1000 system is not designed for use as a polar navigator and operation
outside the approved operating area is prohibited. The GRS-77 AHRS internally monitors
the magnetic field and will display a GEO LIMITS system message when the magnetic
field becomes unsuitable for AHRS operation. When the AHRS can no longer reliably
compute heading, heading information will be removed from the HSI.
AUTOPILOT OPERATION LIMITS

AUTOMATIC FLIGHT CONTROL SYSTEM
AILERON MISTRIM (amber or annunciation on PFD)
Indicates a mistrim of the ailerons while the autopilot is engaged. The autopilot cannot trim the
airplane in roll. During large changes in airspeed, engine failure, or single engine operation,
illumination of this message may occur. If the autopilot is disconnected while this message is
displayed, high roll forces are possible. The following procedure should be followed:
1. Control Wheel .............................................................................................................GRIP FIRMLY
2. Aileron Tab Knob ............................................ ROTATE SLOWLY IN DIRECTION OF INDICATED
MISTRIM UNTIL THE ANNUNCIATION EXTINGUISHES
IF THE ANNUNCIATOR STAYS EXTINGUISHED AND NO OTHER ANNUNCIATIONS ILLUMINATE
• Continue to operate the autopilot in a normal manner after the annunciation extinguishes.
IF THE ANNUNCIATOR REMAINS ILLUMINATED OR REAPPEARS WITH NO CHANGE IN
AIRSPEED OR CONFIGURATION FROM THE PREVIOUS TRIMMED CONDITION:
3. Control Wheel .............................................................................................................GRIP FIRMLY
4. Aileron Tab Knob ....................................ROTATE SLOWLY IN THE DIRECTION OF INDICATED
MISTRIM UNTIL ANNUNCIATION EXTINGUISHES
5. AP/YD DISC / TRIM INTRPT Button ............................................................PRESS and RELEASE
(Pilot’s or Copilot’s control wheel)
6. Roll Trim.........................USING AILERON TAB KNOB, MANUALLY RETRIM AIRPLANE
Autopilot should be considered inoperative until the cause of the mistrim has been investigated and
corrected. Yaw damper may be re-engaged and used normally
ELECTRIC PITCH TRIM INOPERATIVE
NOTE
This condition may be accompanied by a red or annunciation on the PFDs.
1. Move both halves of pilot and copilot pitch trim switches to check for stuck switch
2. AFCS SERVOS Circuit Breaker............................................................................PULL and RESET
(Right circuit breaker panel)
The autopilot will enter Pre-Flight Test (PFT) mode when the AFCS SERVOS circuit breaker is reset.
If the autopilot successfully completes the Pre-Flight Test, re-engage the autopilot, reselect the
desired autopilot modes, and continue to use normally. If the Pre-Flight Test fails, indicated by a red
on the PFDs, the autopilot, yaw damper, and electric pitch trim will be inoperative for the
remainder of the flight.
