777 Tech Paper 12B, 13, 14

The aircraft is on the ground and only one power source is available. Both Centre fuel pumps are selected to ON and fuel is available in the Centre tank but PRESS illuminates in one pump switch. Why?

• On the ground, system logic allows only one pump at a time to operate.

• The pump has failed and due to system logic the OFF light is inhibited.

• Automatic load shedding takes place on the ground with only one power source and as a consequence one pump is OFF.

What mode is the jettison system operating in with the FUEL-TO-REMAIN knob pulled?

• Automatic Mode

• Manual Mode

• MLW Mode

When the airplane is heavy and loaded near the forward CG, fuel is jettisoned

• From the wings and centre tanks simultaneously

• From the wing tanks first

• From the centre tank first

The jettison system can jettison fuel up to:

• Up to 5200 kg of fuel in each wing and centre tank.

• Up to 5200 kg of fuel in each main tank.

• Up to 5200 kg of fuel minimum.

What does the primary L ENG hydraulic pump FAULT light indicate?

• Engine EGT is high or engine speed is low

• The left Engine Primary fuel pump is inoperative

• Hydraulic Pump pressure is low or temperature is high

• The Left Engine is faulty

What does the Demand L ELEC hydraulic pump FAULT light indicate?

• Hydraulic Pump pressure is low or hydraulic pump temperature is high

• The left Engine Primary fuel pump is inoperative

• Automatic systems using the Left System are faulty

• The Autobrake System is faulty

How many hydraulic systems are needed to power enough of the flight Controls for safe flight?

• One system

• Two systems

• Three systems

If the Left and Right hydraulic systems are lost, can the Centre Hydraulic system sufficiently power enough of the Flight Controls for safe flight?

• Yes

• No

When the RAT deploys automatically due to system failures, what does it hydraulically power?

• Alternate gear extension system

• Normal brakes (after landing and airspeed below 60 kts)

• Primary flight controls components normally powered by the centre hydraulic system

• All of the above

AUTOLAND is inoperative for which of the following conditions?

• Left hydraulic system pressure is low

• Centre hydraulic system pressure is low

• Right hydraulic system pressure is low

• All of the above a (CBT)
