2 SYSTEM DESCRIPTION

2.1 G5 Electronic Flight Instrument
2.1.1 G5 Attitude Indicator
The G5 Electronic Flight Instrument configured as an attitude indicator is shown in Figure 2-1. The G5
is an electronic flight instrument display operating as a standalone flight display. It features a bright,
sunlight readable, 3.5-inch color display which is sized to fit in a standard 3-1/8-inch instrument cutout.
The G5 contains integrated attitude/air data sensors that provides display of attitude and secondary
display of air data information. The G5 Attitude indicator configuration is determined at the time of
installation as defined by the AML STC installation data and recorded in APPENDIX A of this
document and maintained with the aircraft records.
Figure 2-1 G5 Electronic Flight Instrument (Attitude)
The G5 calculates aircraft attitude using information from its built-in inertial sensors. If the G5 senses
that the attitude solution is valid, but not yet within the internal accuracy limits, "ALIGNING" is
displayed. The G5 can align itself both while taxiing and during level flight.
The G5 will also use GPS and airspeed data to provide the most accurate attitude information. If none of
these additional sources of information are available, attitude calculations will still be valid but accuracy
may be slightly affected.
