4. Aircraft Design
4-Abreast Configuration Designed to hold 50 Passengers 2 Pilots and 2 Cabin Crew members 1 Galley and 1 Lavatory

5. 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).

6. 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.

7. Power Plant
In 1995, the CRJ-200 series arrived carrying the new General Electric CF34-3B1 turbofan engine.

8. General Electric CF34-3B1 Weight: 1,640 lbs each
Thrust: 8,729 lbs per engine
The Manufacturer does not recommend specific Fire Fighting Technique(s) for their products.
Use your best Judgment!

9. 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.

10. Fuel System 735 Gal 700 Gal 700 Gal 188gal
The Fuel Lines for the Engines and APU Run below the Main Cabin floor and are engine driven.
Optional Tank
188gal
700 Gal

11. Oxygen System under the fuselage, in the front of the wings.
The Oxygen System can be found in the Forward Equipment Bay which can be accessed by a door
under the fuselage, in the front of the wings.

12. There are also two small cylinders stowed in the first overhead compartment of the Main Cabin which are portable for First Aid purposes.

13. 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)

14. Electrical System Turn to RIGHT
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.
Disconnection of the batteries may render fire extinguishing and shutdown systems inoperative. Ensure the aircraft is stabilized before shutting off the batteries
Turn to RIGHT

15. 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)

16. APU Continued
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.

17. Just press the small red button on the bottom left 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.

18. 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.

19. 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).

PBE Unit (Shown Right)
3 Portable Oxygen masks

21. 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.

22. 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.

23. Egress and Emergency Systems
