AHRS AREAS OF OPERATION
For airplanes that have GRS 77 AHRS installed:
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.
For airplanes that have GRS 7800 AHRS installed:
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 84° North latitude at all longitudes
2. South of 70° South latitude at all longitudes
3. 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.
