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
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.
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
TAWS AND TERRAIN SYSTEM LIMITS
Pilots are authorized to deviate from their current ATC clearance to the extent necessary to comply with
TAWS warnings.
The TAWS databases have an area of coverage as detailed below:
a) The terrain database has an area of coverage from North 75° Latitude to South 60° Latitude in all
longitudes.
b) The Airport Terrain Database has an area of coverage that includes airports from North 75°
Latitude to South 60° Latitude in all longitudes.
