AHRS AREAS OF OPERATION
Flight operations with the G1000 Integrated Avionics installed are prohibited in the following regions due
to unsuitability of the magnetic fields near the Earth’s poles:
1. North of 72° North latitude at all longitudes
2. South of 70° South latitude at all longitudes
3. North of 65° North latitude between longitude 75° W and 120° W (Northern Canada)
4. North of 70° North latitude between longitude 70° W and 128° W (Northern Canada)
5. North of 70° North latitude between longitude 85° E and 114° E (Northern Russia)
6. 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
One pilot must remain seated at the controls, with seatbelt fastened, during all autopilot operations.
Do not use autopilot or yaw damper during takeoff and landing.
The GFC 700 AFCS preflight test must be successfully completed prior to use of the autopilot, flight
director or manual electric trim. Use of the autopilot or manual electric trim system is prohibited if the
preflight test is not satisfactorily completed.
NON-ESP EQUIPPED AIRPLANES ONLY - When conducting missed approach procedures, autopilot
coupled operation is prohibited until the pilot has established a rate-of-climb that ensures all altitude
requirements of the procedure will be met.
Minimum speed for autopilot operation is 100 KIAS.
Maximum speed limit for autopilot operation is unchanged from the airplane’s maximum airspeed limit
(V
MO
/M
MO
).
Do not use autopilot below the following altitudes:
(1) On takeoff, do not engage the autopilot below ............................ 400 feet Above Ground Level
(2) Enroute .................................................................................................................... 800 feet AGL
(3) Approach (GP or GS Mode) .................................................................................... 200 feet AGL
(4) Approach (FLC, VS, PIT or ALT Mode) ..................... Higher of 400 feet AGL or Approach MDA
