ATTITUDE INDICATOR
The G1000 attitude indicator is shown on the upper center of the
PFD. The attitude indication data is provided by the GRS 77
Attitude and Heading Reference (AHRS) unit. The G1000 attitude
indicator provides a horizon line that is the full width of the GDU
1040 display.
The roll index scale is conventional with 10° graduations to 30°
and then 15° graduations to 60° of roll. The roll pointer is slaved to
the airplane symbol. The pitch index scale is graduated in 5°
increments with every 10° of pitch labeled. If pitch limits are
exceeded in either the nose-up or nose-down direction, red warning
chevrons will appear on the indicator to point the way back to level
flight. A small white trapezoid located below the roll pointer moves
laterally left and right to provide the slip-skid information previously
supplied by the skid indicator ball. The trapezoid should be
centered below the roll pointer for coordinated turns. The standby
(vacuum) attitude indicator is found on the lower center instrument
panel.
