Air Management Flashcards
List the items that use bleed air
1) ECS
2) Engine Start
3) Anti-Ice
4) Main cabin door pressurization
When is the cabin temp control transferred to the VIP seat panel
When the detect C is selected to the PAX CABIN TEMP CONTROL KNOB
In the event of a bleed leak detection, what light will illuminate in addition to an associated CAS message
The PACK, BLEED 1, BLEED 2, or CABIN APU Amber light
When is the outflow valve (OFV) indication on the ECS synoptic page displayed
It is only available on the ground
What are the potential sources of bleed air that the pneumatic system controller (PSC) can automatically select from
1) Engines
2) APU
3) External Connections.
Is it possible to have bleed air from the from the APU and engines simultaneously
No
During normal operation on the ground for taxiing, what is the primary source of bleed air?
The APU
What is the primary source of bleed air in flight
The engines
When will the bleed air source be automatically transitioned to the engines
When the airplane starts running for takeoff (TLA higher than 50 deg)
The XBSOV (cross bleed SOV) is automatically commanded to close for what conditions
1) Bleed leak
2) Over pressure
3) Engine fire
4) A failure condition is identified.
Can the external ground connection be used to supply pressurized air from an engine start
Yes
if an external pneumatic power source is being used and not adjustable, what range should the pressure supply be in
Between 32 and 60 psi
When is fast cooling enabled on hot days
When the difference between the cockpit and cabin temp set point and the cabin/ cockpit zone temp is equal to or higher than 6 deg C
When is fast warming available on cold days
When the difference between the cockpit/ cabin temp set point and the cabin/ cockpit zone temp is equal to or greater than 6 deg C
What happens to the re-circulation fan during fast cooling or fast warming
it automatically sets a higher speed to optimize system performance.
