FAA APPROVED
ADAHRS
The integral ADAHRS, included in the GI 275 -10, -20, -30, and -40 variants,
senses aircraft attitude and air data for GI 275 display of primary flight data and
can provide attitude and air data for use by other installed systems.
The ADAHRS requires GPS and airspeed inputs for aiding the system. GI 275
includes an optional GMU 11 or GMU 44B magnetometer interface to
determine magnetic heading and an OAT probe for measuring outside air
temperature.
Standby Instruments and the GI 275 ADI
GI 275 installations may provide standby attitude, altitude, and airspeed
instruments. Several types of standby instruments might be installed, including a
standby GI 275 ADI, other ADI, or individual analog instruments.
The GI 275 can be a standalone standby instrument without interfacing to other
sensors and only using its internal sensors. In this configuration, the GI 275 is a
full-time dedicated ADI.
GI 275 system has a configuration for redundancy which is satisfied by using a
GI 275 MFD or HSI that is configured as a standby instrument. This
configuration is only possible when the GI 275 is providing reversionary
capabilities with multiple sensors interfaced to the GI 275. When configured as
a standby instrument with reversionary capabilities, the GI 275 MFD and HSI
include an ADI Page which is displayed automatically when faults are detected
or when selected by the pilot through a reversionary switch.
Both the GI 275 primary and standby ADIs have their own integral ADAHRS
and internal batteries for independence and redundancy.
Backup Battery
The GI 275 may be configured to include a backup battery to provide
emergency power to a GI 275 ADI, HSI or MFD. The backup battery is
mounted in an internal, partitioned aluminum chassis within the GI 275 to
provide thermal security and automatic backup power when aircraft power is
unavailable.
NOTE
Backup battery charging requires the battery temperature between
0°C and 60°C. A system message “Charge Inhibited – unable to
charge the battery” will indicate that the battery is no longer
charging.
