#1 RSVR LOW caution, #1 TAIL RTR SERVO caution, BACK UP PUMP ON advisory, #2 TAIL RTR SERVO ON advisory.
What are the indication when a No. 1 hydraulic system leak exists?
300
The three functions of the back-up pump.
What is 1. supplying hydraulic pressure to the No 1. and No 2. hydraulic systems prior to rotor engagement 2. Only source of hydraulic pressure to the rescue hoist 3. Recharges the APU accumulator?
300
The BACKUP HYD CTRL cb is powered by this bus.
What is the DC essential bus?
300
Draw a picture of the hydraulic system in 60 seconds to include major components.
Picture with 3 pumps, 2 TR servos, 2 transfer modules, 3 Boosted servos: C P Y, Roll servo in the Pilot Assist Servo Assembly. If one team has rescue hoist and the other doesn't that team automatically wins.
