Operating characteristics
(1) Control augmentation system
WARNING: Initiating the
CONTR AUG BIT cycles the
rudder and rudder tab. Ensure
the CONTR AUG BIT is com-
pleted prior to taxi or takeoff.
(2) Turn and roll coordination is
mechanized by the ARI and bank
angle feedback functions when
IAS is less than 217 kts [(nominal)
and, on aircraft 163610 and up;
also 163600 through 166609 after
T-45A AFC-90, when half or full
flap is selected (full slat).] Aileron
position data are supplied to the
YDC from the aileron position
sensor RVDT. Aileron position
data are used with roll attitude
data, AOA data, yaw rate, and
flap discretes to automatically
adjust rudder position at low IAS.
The ARI functions are gain sched-
uled with AOA. On aircraft
163610 and up; also 163600
through 163609 after T-45A AFC-
90, the ARI and bank angle feed-
back functions of the low speed
control laws are deactivated when
the flaps/slats are selected up/in.
Also, all functions of the low
speed control laws (ARI, bank
angle feedback and yaw damp-
ing) are deactivated for yaw rates
exceeding 25 deg/second
