Flight Controls
T-45A UJPT, E2-C2, ADV, & IUT Eng-11
(1) Location: lower trailing edge of
rudder
(2) Function: provides pressure relief
for rudder pedals
(3) Max deflection of 6 degrees +/- 1
degree below 217 KIAS. 1.3
degrees +/- 0.6 degrees at 450
KIAS
NOTE: If directional control is an
issue -- as the aircraft slows below
100 KIAS rudder effectiveness
decreases significantly. A total loss
of rudder effectiveness occurs at
approximately 70 KIAS.

Trim/Yaw Damper Actuator
(1) Location: inside fuselage, at root
of vertical stabilizer
(2) Function: electromechanical
device moves rudder trim tab upon
input from trim switch or
automatically through the yaw
damper controller (computer)
when the rudder is moved [yaw
damper controller receives data
from SAHRS and Stability
Augmentation Damper Sensor
(SADS)]
d.
Rudder/Yaw damper actuator linkage
Overlay 4
Rudder/Yaw Damper Linkage
(1) Location: Below YDA at root of
vertical stabilizer
(2) Function: mechanical linkage
moves rudder and rudder trim tab
through the automatic feature of
the YDC
