Attitude Indicator
The primary attitude indicator is show on the upper center of the PFD
and displays pitch, roll, and slip/skid information provided by the
Attitude and Heading Reference System (AHRS).
Above and below the horizon line, major pitch marks and labels are
shown for every 10°, up to 80°. Between 25° below and 45° above the
horizon line, the pitch index scale is graduated in 5°increments with
every 10° of pitch labeled. Between 20° below and 20° above the
horizon line, minor pitch marks occur every 2.5°. If pitch limits are
exceeded in either the nose-up or nose-down attitude, red warning
chevrons will appear and point the way back to level flight. The roll
index scale is graduated with major tick marks at 30° and 60° and
minor tick marks at 10°, 20°, and 45°. The roll pointer is slaved to the
airplane symbol. The slip-skid indicator is the bar beneath the roll
pointer. The indicator moves with the roll pointer and moves laterally
away from the pointer to indicate lateral acceleration. Slip/skid is
indicated by the location of the bar relative to the pointer. One bar
displacement is equal to one ball displacement on a traditional slip/
skid indicator.
Standby Attitude Indicator
The standby attitude indicator is mounted on the LH bolster panel and
gives backup indication of flight attitude. Bank attitude is indicated by a
pointer at the top of the indicator relative to the bank scale with index
marks at 10°, 20°, 30°, 60°, and 90° either side of the center mark. A
fixed miniature airplane superimposed over a movable mask
containing a white symbolic horizon bar, which divides the mask into
two sections, indicates pitch and roll attitudes. The upper “blue sky”
section and the lower “earth” sections have pitch reference lines useful
for pitch attitude control. A knob at the bottom of the instrument allows
adjustment of the miniature airplane to the horizon bar for a more
accurate flight attitude indication. A PULL TO CAGE knob on the
indicator is used for quick erection of the gyro. When the caging knob
is pulled, the pitch and roll indications will align to within 2° of their
respective fixed references.The standby attitude indicator is
electrically driven. A red GYRO flag indicates loss of electrical power.
Redundant circuits paralleled through diodes at the indicator supply
DC electrical power for gyro operation.
28 VDC for attitude gyro operation is supplied through the 5-amp
STDBY ATTD 1 circuit breaker on the ESS BUS 1 and the 5-amp
STDBY ATTD 2 circuit breaker on the MAIN BUS 1.

Airspeed Indicator
Primary airspeed data is provided by the Air Data Computer and is
shown as a vertical tape along the upper left side of the PFD. The
airspeed scale is graduated with major tick marks at intervals of 10
knots and minor tick marks at intervals of 5 knots. Speed indication
starts at 20 knots, with 60 knots of airspeed viewable at any time. The
