Air Conditioning & Pressurization Flashcards
The left and right air conditioning packs are respectively powered by which electrical buses?
Left pack is powered by DC ESS BUS
Right pack is powered by DC BUS 2
In the event of a single pack failure, can the remaining pack supply sufficient conditioned air for continued flight at high altitude?
Yes
In the event of a double-generator failure when airborne, the deployment of the ADG will provide electrical power for continued operation of which pack?
The left pack is powered by the DC ESS BUS. The operational ADG will provide power to the AC ESS BUS which will power the DC ESS BUS through the ESS TRU 1.
The ACU valves operate in two different modes. What is ‘Low Mode?’
Bleed air supplied by the engines, both packs operating, output pressure 24 psig
The ACU valves operate in two different modes. What is ‘High Mode?’
Airborne during single-pack operation, or on the ground with the APU supplying the bleed air, output pressure 39.5 psig.
NORM mode temperature control range is from:
60F to 90F
STBY mode temperature control range is from:
35F to 180F
MAN mode temperature control range is from:
35F to 200F
Amber CABIN ALT caution EICAS indicates a cabin altitude between:
8,500 and 10,000 feet
Red CABIN ALT warning EICAS indicates when cabin altitude exceeds:
10,000 feet during low-altitude airfield operation, or 14,500 feet during high-altitude airfield operation.
Red DIFF PRESS warning EICAS displays when:
Cabin pressure differential exceeds 9.0 psi.
How many cabin pressure acquisition module(s) [CPAM] does the CL-650 have?
Two.
CPAM 1 and CPAM 2
The cabin pressure acquisition module (CPAM) provides the data concentrator units (DCU) with what pressurization data for display on the EICAS?
Cabin altitude (ALT) Cabin rate of climb or descent (RATE) Differential pressure (P)
If PASS SIGNS switches are selected to AUTO, the CPAM will cause the NO SMKG and SEAT BLTS signs to illuminate when the airplane’s cabin altitude exceeds:
10,000 feet
