T-45C TS, ADV & IUT ENG-12
Hydraulic Subsystems Malfunctions
B. Verifications
1. In retract mode, landing gear handle light remains illuminated (red)
2. Wind noise/drag from landing gear doors may be apparent
3. Visual by other aircraft or tower, if available
C. Effects on flight safety
1. Airspeed restricted to less than 200 KIAS
2. Open door fouls the arresting gear
III. Wheel brake failure
Fig 4: Wheel Brake/
A. Indications
Anti-Skid System
Operation
1. Lack of brake pedal pressure (one or both pedals)
2. Aircraft fails to slow when brake pedal pressure applied
3. Aircraft pulls to left or right upon application of brake pedal pressure
B. Verifications: indications are verification
C. Effects on flight safety
1.
Loss or reduction of ability to control speed on ground
2.
Loss of differential braking
3.
Loss of anti-skid
IV. Wheel brake/emergency flap accumulator failure
Fig 4: Wheel Brake/
A. Indications: wheel brake/emergency flap accumulator pressure gauge
Anti-Skid System
in starboard wheelwell and left console BRAKE gauge display 0 psi
Operation
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.
