An Introduction to the CRJ 100/200
Entering service in November 1992, the Bombardier CRJ 100
pioneered the 50 seat jet-class. Today, along with the 200
series they are flown by over 30 different operators on all five
continents and serve over 6 million passengers a year.

2 Pilots and 2 Cabin Crew members
1 Galley and 1 Lavatory
Lavatories
• There is one lavatory
located in the aft section
of the passenger cabin.
• Fire detection (overhead
smoke detector).
• Extinguishing (Halon 1211
in waste basket only).
Galleys
• There is one galley located in
the front of passenger cabin,
between the L1 door and
the R1 door.
• Includes 2 Refrigerators, 2
Coffee makers and 4 carts
units.
Power Plant
Powerplant Continued
 The engine is a twin spool turbofan
design. This means that if you intend
to put out an engine fire do not try to
extinguish it by spraying water into
the front of engine.
 The power plant in the CRJ 100/200 is
made up of several titanium disc fans
surrounded by Kevlar to protect the
rest of the aircraft in case of a
catastrophic engine failure.
 Keep in mind that the skin of the
aircraft, including the engine cowling,
are made of aluminum alloy.
Fuel System
700 Gal
735 Gal
The Fuel Lines for the Engines and
APU Run below the Main Cabin
floor and are engine driven.
700 Gal
Optional Tank
188gal
There are also two small cylinders stowed in the first
overhead compartment of the Main Cabin which
are portable for First Aid purposes.
Hydraulic System
• Triple Redundant System.
• Normal Pressure 3000 PSI
• System 1 : Provides power to the Left side primary flight controls as
well as the flight and ground spoilers on both sides.
• System 2 : Provides pressure to the Right side primary flight controls, as
well as the right side spoileron, right aileron, rudder and elevator,
outboard brakes and the main landing gear assist and auxiliary
actuators).
• System 3 : Provides pressure to the flight controls on both sides,
landing gear, inboard brakes, and nose wheel steering.
Systems 1 and 2 are located in the aft equipment bay. System 3 is located in between
the main wheel wells
Each system runs independently and each contain 6 pumps. 2 of which are engine
driven and 4 that are alternating current motor pumps (ACMP)
Electrical System
 Two 28V nickel-cadmium batteries located
in the Aft Equipment Bay on the forward
pilot side.
 To access the batteries, open up the
equipment bay door located on the
bottom of the tail section. Push the
button and the release handle forward.
They can be shut off by using the quarter-
turn quick disconnects. They can be shut
off by using the quarter-turn quick knob
(shown left; Grey knob) to the RIGHT.
Auxiliary Power Unit (APU)
• Housed in a fire-proof enclosure
located in the aft equipment bay
in the aircraft tail cone
• APU drives the aircraft’s electric
generator and draws its fuel using
the same pump as the engines
• The APU can be shut down by
activating the remote cut-off
switch at the external services
panel located on the Co-pilot side
of the aircraft’s nose or by the
emergency shutdown button ( see
next slide)
APU Continued
AFT Equipment Bay (Pilot Side Front)
• The APU Emergency
Shutdown button
(Shown left) is located in
the Aft Equipment Bay
below the battery.
• The APU is located
above it in the upper
left-hand corner.
APU Continued
The external APU shutoff also has a
location in one of the front right
panels.
Just press the small red button on the
bottom left corner.
Fire Detection
 The CRJ-200 has fire detection and extinguishing capabilities in the engine nacelles and
the APU only.
 It has smoke detection in the cargo compartments and lavatories only.
 It also has fire and overheat detection in the jetpipes, engine pylons, and main landing
gear bins.
Fire Suppression
Lavatory (Waste Basket
Only)
 Fire extinguishing is available for the Engines (2 Bottles can be
used for either or both) APU, cargo and lavatory (waste basket
only).
Flight Deck Emergency Equipment
Located Behind the F.O.
• 3 Life Vests
• Escape Rope (15’)
• Crash Axe
• Halon Fire Extinguisher
• PBE Unit (Shown Right)
• 3 Portable Oxygen
masks
Brakes and
Wheels
• Equipped with multiple disc steel
brakes (Outer and Inner) and
Hydro Aire Mark III anti-skid
units.
• Tires are filled with nitrogen gas
at 300 PSI.
• Wheel fuse plugs can blow out
after 3 minutes at 150°C.
• Landing gear may not lower at
speeds in excess of 250 KIAS.
• Hydraulic System 2 will assist
with extension during manual
landing gear extension.
Composition of
Wheels
 Like most of the aircraft, the brake
and wheel assembly consist of
metals. Mostly aluminum alloys
and magnesium, which is a
combustible metal.
 Take care to use the proper
extinguishing agent on burning or
hot brakes.
Egress and Emergency Systems
There is no peephole
on the cargo Door
Limit on the Door 1000 lbs, or 4 passengers
Emergency Floor Lighting: Runs on 4 rechargeable batteries that last 15 minutes.
Egress Continued
The CRJ-100/200 Series DOES NOT feature Door Slides.
Door Operation
 To open the L1 door for egress push in
the outer handle trigger plate.
 The outer handle ejects from the door
recess.
 The pressurization flap opens.
 Rotate the handle counterclockwise to
the OPEN position.
 The door latch mechanism unlocks.
 The latch cams and latch pins

disengage from the door frame fittings.
The fwd and aft pull-in levers open the
door to a near vertical position.
The door descends in a gradual
downward movement.
The two folding handrails deploy.
The support wheel extends and locks
in place before reaching the ground.
Doors Continued

has simple instructions
labeled on the door
itself.
 Just push the knob, turn
the handle
counterclockwise and
pull.
Doors Continued

found on either side of the
aircraft.
 To open from the outside, push
in the panel at the top of the
door, grab the handle. Pull the
top of the door and push the rest
of the door inward to open it.
