What happens to the pack flow control valves during engine start?. They must be selected off. They must be selected off on cold days only. They must be selected off on hot days only. They automatically close.

The temperature of each aircraft zone is optimized by means of: a HOT AIR valve. a ZONE control valve. A PACK FLOW VALVE. A TRIM AIR valve.

When does normal automatic pressurization occur?. After second engine start. Pressurization occurs during taxi. Pressurization occurs during the takeoff roll. After rotation.

What computers control the cabin and cockpit conditioned air?. Two pack controllers that pass information and requests to three zone controllers. Three zone controllers that pass information and instructions to two pack controllers. One zone controller that passes information and instructions to two pack controllers.

Pressurization is normally automatic. Can you interfere with it?. Yes, CABIN PRESS MODE SEL to OVERRIDE and MAN V/S CTL toggle switch. Yes, manually set landing elevaton using the LND ELEV AUTO selector. Yes, PRESS ENG 1 OR 2 BLEED to OVERRIDE and MAN V/S CTL.

What is the function of the ram air valves?. Emergency smoke removal and ventilation in the event of dual pack failure. Avionics cooling. Cargo ventilation & avionics cooling.

With the pressurization system in the automatic mode, which valves are closed when the ditching push button is selected on?. All valves below the water line. APU inlet. The engine bleed valves. Only the avionics cooling valves.

When APU is supplying the packs, the pack controller sends a demand signal to increase airflow when a zone temperature cannot be satisfied. This signal is sent to the: Pack Ram Air Inlet Flap. APU ECB. Pack Outflow Control Valve.

Trim air valves are modulated by: The zone controller. Anti-ice valve. Hot air pressure regulating valve.

During Ground function operation, the outflow valves are: Fully open. Fully cosed. Positioned according to FMGS demands.

The outflow valve is powered by: One of two electric motors. One of three electric motors. Three mechanically linked hyd motors.

The purpose of the safety valve is to avoid: Excessive positive pressure differential. Excessive negative pressure differential. Both are correct.

When landing elevation is set to AUTO, the landing elevation is sent to the controller from: FMGEC. FCU. ADIRS.

What does the air conditioner mixing unit do?. Mixes air coming direct from the engines and packs. Mixes air coming from the cabin and direct engines. Mixes air coming from the cabin and packs. All of the above.

Hot air from the pneumatic system provides wing-anti-ice to: The four outboard slats and the horizontal stabilizer. The four outboard slats. All slats.

You are on the ground and the wing anti-ice pushbutton is set to the ON position. Wing anti-ice valves will remain open until the wing anti-ice pushbutton is selected off. Wing anti-ice valves will open and then close immediately. Wing anti-ice valves will open for 30 seconds and then close as a ground test is initiated.

With reference to the PROBE/WINDOW HEAT pushbutton, which of the following is true?. The system should only be selected ON in icing conditions. When in AUTO mode, the windows are heated only when necessary. The system should only be selected ON after first engine start. Window heating comes on automatically after first engine start.

Which one of the following statements is true?. There are 2 wing anti-ice valves installed on each wing. When the engines anti-ice is operating, continuous ignition is automatically activated. Both are correct.

When both ENG 1 and " pushbuttons are turned ON, each engine nacelle is anti-iced by: The pneumatic system. Electric heat elements. Independent bleed air source from HP compressor.

If one engine anti-ice system fails, the second one takes over and provides anti-icing for both engines. True. False.

On ground and at ramp, windshields, windows and probes are heated: Automatically when one engine is running or manually by switching ON the PROBE/WINDOW HEAT pushbutton. On high heat only. On low heat when one APU is running ad high heat using manual PROBE/WINDOW HEAT pushbutton.

Rain protection is provide by: Warm bleed air blowing to the windshield. Rain repellant and Windshield wipers. Both are correct.

the RAIN RPLNT (rain repellant) pushbutton is inhibited on the groud when the engines stopepd. True. False.

How are controlled the engine Anti ice Valves?. There is one pushbutton sw for each engine. One pushbutton sw for the two engines. Automatically.

The FAV ins controlled by the BMC through the Control Thermostat (ThC). The temperature regulation gives two teperature settings: 150°C for nominal conditions / 200°C on demand from the air conditioning system. 40°C for nominal conditions / 100°C on demand from the air conditioning system. 200°C for nominal conditions / 150°C on demand from the air conditioning system.

The sensing elements have a solid center conductor set in an aluminum oxide insulator and are integrated in an outer tube connected to A/C ground. Helium gas fills the space between the outer tubing and the center conductor. Ceramic Oxide (Eutectic salt) fills the space the outer tubing and the center conductor. Nitrogen gas fills the space the outer tubing and the center conductor.

The crossbleed valve is an electrically controlled butterfly shut-off valve. Two electrical motors, which work independently, are used for manual or automatic operation. True. False.

Why does the APU bleed valve not open when a LH wing or pylon 1 leak occurs?. Because the crossbleed valve is open. In order to protect the surrounding area. In order to protect the right hand bleed system.

The main air sources are the engines. Air can bleed from two different stages. It is generally bleed from _________ to minimize fuel penalty. When pressure from the IP bleed port is insufficient to supply the network, air is automatically bleed from _________. IP compressor stage 6 / HP compressor stage 8. IP compressor stage 8 / HP compressor stage 6. IP compressor stage 3 / HP compressor stage 3.
