T-45C TS, ADV & IUT ENG-27/ENG-28
Engineering Review
(6) Nose wheel steering: available with
generator failure
G. Hydraulic Subsystem Malfunction
1.
Wheel brake/emergency flap accumulator failure
Sg 7, fr 45
Wheel Brake/
a.
Indications: wheel brake/emergency flap
Emergency Flap
Accumulator Failure
accumulator pressure gauge in starboard
wheelwell and left console BRAKE gauge
display 0 psi
NOTE: Under normal conditions the wheel
brake/emergency flap accumulator pressure
gauge and brake gauge should display a mini-
mum of 1300 psi on preflight and 3000 psi with
the engine operating.
b.
Verifications: braking may be jerky and/or
uneven
c.
Effects on flight safety
(1) No backup brake system if HYD 1
inoperative
(2) No backup flaps system if HYD 1
inoperative
NOTE: Slats not available. Slats do not
have a backup.
VI. Flight Control System
NOTE: The flight controls consist of ailerons to control roll,
stabilator to control pitch, and rudder to control yaw. The
control augmentation system enhances flight characteristics
and compensates for pitch transients during speed brake
Sg 8, fr 1
operation. The T-45C also employs flaps and slats to
Flight Control System,
increase lift and speed brakes to increase drag. All flight
Flap/Slats, Speed
controls except the rudder are hydraulically operated. The
Brakes
rudder is a mechanical system and should be secured with
the gust lock lever when the aircraft is parked.
