How many cargo compartments and where are they
3
FWD and AFT cargo compartments on the right side
Bulk cargo compartments on the left rear
What is EICAS
Engine Indicating and Crew Alerting System
What do ALL cargo compartments have?
All pressurized and heated
smoke detection and extinguishing systems
What is the volume of each cargo compartment?
Containerized cargo only in FWD and AFT
FWD - 3 16L ULD
AFT - 3 12L ULD
Bulk - loose cargo for baggage and live animals and has additional ventilation
(ULD universal loading devices)
Where is Refueling accomplished
only on the left wing
What are the two equipment compartments
FWD
AFT
Where are the Ext Power Receptacles and what sources do they supply?
Why Two?
Both on the LEFT side
FWD External Power Receptacles - accepts two power sources left and right
AFT External Power Receptacles - only accepts one power source
(Normally the FWD is used. The AFT is added only to assist in starting the right eng with the APU is Inop.)
What is the CCS?
Common Core System
a network which allows all of the different computing functions and remote inputs to be centrally processed
Left and Right CCR Common Computing Resource both located in the FWD E/E
(Reset located next to FD door power buttons)
When does the CCS boot up?
When the Ext power is AVAIL
Left boots up first (2-3 Min) then right
if only Batter pwr available Left CCR only
to start the APU Left CCR has to be booted up
How long does it take to boot up a CCR?
How do you know its finished?
2-3 Min
Captains inbd display and Lower display (both CDU’s) are available
How do you know both CCR’s are on line?
All Flight deck Displays and both HUD’s on
Describe the Passenger oxygen system
Gaseous Hight pressure bottle system that delivers O2 to the PSU passenger service units
oxygen is provided for 22 min
What is a POB?
Portable Oxygen Bottle
What is the only system that uses bleed air?
Engine Anti Ice
How is the conditioned zoned in the plane?
5 Zones
1 FLT deck
4 Cabin
How is air supplied to the aircraft?
CAC’s
each Pack is equipped with 2 air compressors ecause there is no pneumatic system
How is Cabin Pressurization controlled?
Through 2 identical outflow valves
AFT
FWD
(half of the outflow is discharged through each valve)
How is Cabin Pressure operated
Fully automatic and operated by the Flight Management Computer FMC
What Protection systems do we have for the pressurization system
2 Positive Pressure Relief Valves
2 Negative Pressure Relief Vents
