GRT Avionics Mini-X Installation, Setup & User Manual
1.4 AHRS Specifications and Limitations
� Maximum Angular Rate: 250 deg/sec
� Maximum G-Limit : 4G for unlimited time, 10G for up to 20 seconds. G-limit affects accuracy of
the readout, but exceeding it will not damage the instrument.
� Ambient Temperature Range for full accuracy: -10°F to +150°F
� Airspeed Range : 30-335 mph IAS (stock AHRS) or 50-600 mph IAS (High-Airspeed version)
� Altimeter Range : -2000 to +40,000 feet
� Magnetometer Type: Internal (Mini-B and stock Mini-X) or External remote (Mini-AP and optional
for Mini-X). When the External magnetometer is installed, it overrides the Internal, which is then
used only in the unlikely event of failure of the remote unit.
1.4.1 Mini-X AHRS and Loss of GPS Data
Normal Operation
Attitude data will be full accuracy when valid external magnetometer data or GPS ground track
data is available. If no valid external magnetometer is available, and the GPS ground track data is
lost (because the airplane is moving less than 4 mph, or the GPS is not able to provide position
data), and the AHRS will attempt to use its internal magnetometer. If the internal magnetometer
is too inaccurate due to magnetic disturbances near the instrument, the ground track display on
the PFD screen will show dashes. The AHRS will provide full accuracy attitude information for at
least 5 minutes.
CAUTION: If the EFIS is unable to provide any heading or track data (the heading/ground track
display on the PFD screen is shown as dashes) for extended periods of time (more than 5 minutes)
the attitude data could become less accurate.
