Pneumatics Flashcards
- The pneumatic system supplies high pressure air
a. only for air conditioning , engine starting, and wing anti-ice
b. only for the hydraulic and water reservoir pressurization
c. for air conditioning, engine starting and wing anti-ice as well as for hydraulic and water reservoir pressurization
c. for air conditioning, engine starting and wing anti-ice as well as for hydraulic and water reservoir pressurization
- The engine bleed system is controlled and monitored:a. the central computerb. two components, one primary and the second in standbyc. one dedicated Bleed Monitoring Computer (BMC) for each engine
c. one dedicated Bleed Monitoring Computer (BMC) for each engine
- Am amber crossbleed valve symbol on the ECAM BLEED page indicates:a. The crossbleed valve is open under normal condition
b. The crossbleed valve is in transit
c. Data for the croosbleed valve is not available
b. The crossbleed valve is in transit
- Normally the engine bleed is coming from the IP stage of the compressor. When the pressure from IP stage is not sufficient:a. the crew needs to select high pack flow
b. air is automatically bled from the HP stage
c. crew should start APU to increase bleed air supplied by ENG bleed
b. air is automatically bled from the HP stage
- Bleed air supplied by the APU:
a. is not available in flight
b. is not available for air conditioning
c. is controlled by APU bleed valve and is available on the ground and in flight with altitude restrictions
c. is controlled by APU bleed valve and is available on the
ground and in flight with altitude restrictions
- White GND on bleed page:a. turns amber if pressure is out of limit
b. indicated in white, turns green when external air is connected
c. indicates external air may be connected. It is not displayed in flight
c. indicates external air may be connected. It is not displayed in flight
- With the APU master switch ON and the APU start pb pushed to ON, the ECAM bleed page shows:
a. white APU with green cross line valve
b. white APU only
c. amber APU
a. white APU with green cross line valve
- With APU supplying the pneumatic systems and cross bleed selected closed:a. all engine bleed valves will close
b. all engine bleed valves will open
c. bleed valve on left side is close and bleed valve on right side is open
c. bleed valve on left side is close and bleed valve on right side is open
- In flight with engine 1 shutdown:
a. Crew should select crossbleed to OPEN
b. Crew should not select crossbleed to OPEN as this will cause all engine bleed valve to close
c. Crossbleed valve automatically opens after a time delay
a. Crew should select crossbleed to OPEN
- If an engine bleed pylon leak is detected, the bleed valve on same side closes, the crossbleed valve receives a closure signal and:a. a FAULT light appears only in the ENG BLEED pb associated with the pylon leak and wing anti-ice must not be used
b. FAULT lights appears in both ENG BLEED pbs
c. Crossbleed valve receives a closure signal and wing anti-ice may be used
a. a FAULT light appears only in the ENG BLEED pb associated with the pylon leak and wing anti-ice must not be used
- In flight with a left wing leak warning you would not use wing anti-ice because:a. pneumatic air pressure is insufficient
b. pneumatic air temperature will be out of limits
c. only one wing would be de-iced
c. only one wing would be de-iced
- When ENG 1 bleed fault appear on ECAM: (due to overheat)a. FAULT light in ENG bleed p/b remains on as long as the failure is present
b. FAULT light goes out if ENG bleed p/b pushed OFF with failure present
c. Amber FAULT and white OFF light appear in engine bleed p/b
a. FAULT light in ENG bleed p/b remains on as long as the failure is present
- The crossbleed valve is automatically controlled to:a. close after all engine starts even if the APU bleed is still ON
b. open when the APU bleed is selected ON, and closed when a leak is detected
c. open when one engine bleed has failed
b. open when the APU bleed is selected ON, and closed when a leak is detected
- When a leak is detected on the APU bleed, amber ECAM message “AIR APU BLEED LEAK” is presented. According to this indication:a. the APU is shut down
b. the engine bleed valves are closed
c. both the APU bleed valve and the crossbleed valve are closed
c. both the APU bleed valve and the crossbleed valve are closed
- In case of BMC failure:
a. the adjacent BMC takes over most of the monitoring functions
b. the adjacent BMC takes over all of the control functions
c. the engine bleed is lost
a. the adjacent BMC takes over most of the monitoring functions
