777 Tech Paper 2B & 3A

Where is the target temperature for the air conditioning zones displayed?

• On the lower EICAS display when pressurisation is selected to MAN

• On the AIR synoptic, display in magenta

• On the upper EICAS display when pressurisation is selected to MAN

• On the HYD synoptic

In the STBY COOLING MODE what will the pack automatically do if the airplane is not in an area of sufficient cooling?

• Decrease airflow to half rate

• Shutoff the pack

• Fail the Pack Standby Cooling controller

• Increase airflow through the pack

What does a PACK MODE R EICAS message indicate?

• The pack will operate in the STBY COOLING MODE

• The pack will NOT operate in the STBY COOLING MODE

• The STBY COOLING MODE has failed

• The airplane is in unfavourable conditions and pack output temperature is too high

What landing altitude is displayed in the EICAS pressurisation system indications when the airplane has travelled more than 400 miles or passed the halfway point?

• The Departure airport altitude to the nearest 100 feet

• The Destination airport altitude to the nearest 100 feet

• The Destination airport altitude to the nearest 500 feet

• The Alternate airport altitude to the nearest 50 feet

What landing altitude is displayed in the EICAS pressurisation system indications when the airplane has travelled less than 400 miles or before the halfway point?

• The Departure airport altitude to the nearest 100 feet

• The Destination airport altitude to the nearest 100 feet

• The Destination airport altitude to the nearest 500 feet

• The Alternate airport altitude to the nearest 50 feet

During pre-flight what position should the FWD and AFT OUTFLOW VALVE switches and LDG ALT selector switches be in?

• OUTFLOW VALVE switches in AUTO and LDG ALT selector pulled OUT

• OUTFLOW VALVE switches in OFF and LDG ALT selector pushed IN

• OUTFLOW VALVE switches in AUTO and LDG ALT selector pushed IN

• OUTFLOW VALVE switches in MAN and LDG ALT selector pushed IN

To control Outflow Valves manually, what position should the landing altitude switch be in?

• Pulled out

• Pushed In

• Irrelevant

What action is required during pre-flight if the LANDING ALTITUDE EICAS message is displayed with the FWD and AFT OUTFLOW VALVE switches in AUTO?

• Push the LDG ALT selector IN

• Pull the LDG ALT selector OUT

• Select the FWD and AFT OUTFLOW VALVE switches to MAN

• Both A and C are correct

Conditioned air enters the flight deck through:

• Left Pack

• Right Pack

• Bleed air duct

• Conditioned air manifold

Why does the Flight Deck receive air from the left pack at a higher pressure than the passenger cabin?

• The pilots demand it

• To prevent smoke from entering the cockpit

• To defog the forward windows

• To cool the equipment in the aisle stand
