Pneumatics Flashcards
In the event there is insufficient pressure to accommodate the system’s demand, bleed air will be supplied by the sixth-stage bleed air port instead. True/False?
False, it will be supplied by the 10th stage.
Normally, the tenth-stage bleed air is used to supply bleed air to the pneumatic system. True/False?
False, the sixth-stage bleed air is the normal supply.
There is an external air inlet provided on the ___. It allows an external air source to be used to pressurize the manifold for engine starting.
Left aft fuselage.
The pneumatic system supplies bleed air for engine starting, cowl and wing anti-ice, the air conditioning, and pressurization system. True/False?
True
The Pressure Regulating Shutoff Valve, or PRSOV, is also called the engine bleed valve. True/False?
True
The pneumatic system is controlled by the BLEED AIR Control Panel. The control panel is located on the flight deck overhead panel. True/False?
True
The purpose of the PRSOV is to limit engine bleed air pressure and to shut off bleed air supply from the associated engine. True/False?
True
The APU Load Control valve is electrically controlled an pneumatically operated. True/False?
True
The only indication that an external pneumatic air cart is supplying the pneumatic system is the ground cart pneumatic air pressure that is displayed on the ECS Synoptic page. True/False?
True
In auto mode, the ACSC commands the APU to supply pneumatic air to the anti-ice systems. True/False?
False
The bleed air leak system monitors, the left and right bleed zones, the left and right cowl anti-ice zones, and the wing anti-ice zone. True/False?
True
The Pneumatic System of the CRJ provides ___ for sue by many of the aircraft’s other systems.
High Temperature, High Pressure Air
The ISOL switch pneumatically opens or closes the bleed air isolation valve. True/False?
False, it electrically opens or closes it.
The Bleed Air valves should be open when the ground cart is supplying the pneumatic system. True/False?
False, they should be closed.
The dual loop leak detection loop does not extend to the outboard end of slat three. Leak detection in this area is provided by an outboard skin temperature sensor. True/False?
False
