Question 11

What occurs during a Utility Hydraulic low level condition?

Answer 11

The reservoir piston, driven by IPAS air, closes the low level valve, which is a pilot valve for the auxiliary isolation valve, which denies hydraulic power to the AWS turret, external stores actuator and ammo carrier drive. In addition, the low level switch is actuated, which sends a 28VDC signal to the emergency hydraulic shutoff valve (solenoid) which cuts pressure to the tail wheel lock control valve and utility side of tail rotor servoactuator.
