?
What does the AOA system consist of, and
what is its primary function?
ANSWER:
1. The AOA system consists of the AOA indicator
and AOA indexer (located on the instrument panel
in both cockpits), the external approach lights
ANGLE OF ATTACK SYSTEM
(located on the nose landing gear), and the AOA
transmitter probe (located on the forward left side
of the aircraft fuselage).
2.
The AOA system is primarily used during all
approaches and landings to provide pilots with the
necessary cues to maintain the precise airspeeds
necessary for making carrier landings.

Location: top of instrument panel, left of
HUD, front cockpit; left of gunsight, rear
cockpit
2.
Function: indicates AOA, using pointer and
scale graduated from 0 to 30 units. The
pointer position is proportional to the local
AOA signal provided by an AOA
AOA INDICATOR
transmitter, via two DC potentiometers, to
AOA indicator in each cockpit
