The G5 Electronic Flight Instrument configured as an attitude indicator, is shown in Figure 1-1. The G5 is
an electronic instrument display operating as a standalone flight display. It features a bright, sunlight

1.6.1.1 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 attitude functions are shown below:
• Pitch
• Roll
1.6.1.2 Turn Rate
The Turn Rate Indicator is located at the bottom of the display. A magenta Turn Rate Trend Vector shows
the current turn rate. A standard-rate turn (3 deg/sec) is shown on the indicator by the trend vector
stopping at the standard turn rate tick mark.
1.6.1.3 Slip/skid
The Attitude Indicator displays slip/skid information as indicated by the location of the ball at the lower
center portion of the indicator.
