SO1115 FLT controls/Hydraulics (part 1)

Question 1

Name of the two hydraulic systems?

Answer 1

Utility (left) and Flight control (right)

Question 2

Hydraulic systems operate at ______ psi

Answer 2

approx. 3000

Question 3

How is the hydraulic reservoir pressurized?

Answer 3

Bleed air from the engine

Question 4

What should thehydraulic fluid level read between?

Answer 4

FULL and REFILL (air bubbles causing lvl to be above FULL can be tolerated)

Question 5

Normal hydraulic operating pressure?

Answer 5

2850-3200 psi

Question 6

A gearbox failure to shift will also mean loss of hydraulic pressure?

Answer 6

False. Hydraulic pump can function on either gearbox speed.

Question 7

A gearbox failure will cause what?

Answer 7

Hydraulic pressure and generator failure.

Question 8

How are the hydraulic pressure indicators powered? (AC/DC)

Answer 8

AC

Question 9

When does the hydraulic caution light come on and go out?

Answer 9

On 1800 psi

Question 10

The hydraulic caution light will come on for a hydraulic overtemp.

Answer 10

False. Only way to see an overtemp is to look at indicator (high pressure most likely)
