ANGLE-OF-ATTACK INDICATORS (OPTIONAL)
The optional Angle-of-Attack (AOA) indicators system consists of two
angle-of-attack indicators mounted in the instrument panel, one out-
board of the pilot PFD and one outboard of the copilot PFD, Figure 5-5.
The angle-of-attack indicators display continuous angle-of-attack posi-
tion to the flight crew. The AOA indicators are driven by the stall warn-
ing computer. The dual channel computer provides buffered outputs to
the indicators for protection. The pilot AOA indicator receives data
from the left channel of the stall warning computer and the copilot
AOA indicator receives data from the right channel of the stall warning
computer. The AOA indicator is adequately marked displaying .10, .20,
.30, .40, .50, .60, .70, .80, .90, 1.0 with unnumbered marks half way be-
tween each. The beginning of the red band at .80 represents shaker ac-
tivation and an imminent stall condition. The AOA indicators front
plate markings are consistent with the stall warning information
shown on the PFDs, a tape type presentation at the end of the airspeed
tape. The AOA indicators are powered via the L STALL WARN and R
STALL WARN circuit breakers located on the pilot's and copilot's cir-
cuit breaker panels (FLIGHT group).
