APR switch in the ARM position
Both engines above 79% N1
Both Throttles in a takeoff position
(True or False) With the APR appropriately ARMED, it will activate when either engine drops below 67.6% N1.
TRUE
When is continuous ignition required?
Takeoff or landing on contaminated runways
Takeoff or landing with a 10KT or greater crosswind component
In the vicinity of thunderstorms
In MDT or greater rain
In MDT or SVR turbulence
What is the difference between gravity fuel and pressure fuel?
Gravity fuel is achieved by using the overwing fuel caps
Pressure fuel is only achieved by using the single-point refueling point
Pressure fuel maximum tank quantity will always be greater than gravity fuel maximum quantity
The maximum fuel quantity for the CRJ 200 is
14518
From which tank does fuel go directly to the engines?
Collector tanks
How can the crew identify if the aircraft is currently receiving fuel from the single point refueling system?
By reading the AUTO XFLOW INHIBIT annunciator on ED2
How is it possible to check fuel quantity if the electronic fuel capacitance system is not functioning?
Using the MLI system
(True or False) The ejector pumps require fuel flow from another fuel pump in order to function.
True
How many ejector pumps does the CRJ fuel system have?
6
(True or False) Both electric fuel pumps will run even if only one armed.
True
How does fuel in the Center tank reach the engine?
From the Center to the Wing tanks then to the Collector tanks and then to the engine
The electric fuel pumps will run when armed,
- during engine start
- when fuel pressure to either engine driven pump drops below 9 PSI
The maximum allowable fuel imbalance is
800 lbs
The minimum fuel for takeoff is (TOTAL)
or (Each Wing)
900
or 450 each wing
What is the purpose of the APU/XFLOW fuel pump?
Sends fuel to the APU
Transfers fuel from one wing tank to another
The CRJ will automatically transfer fuel from one wing tank to another if the imbalance reaches
200lbs
When must auto crossflow (automatic fuel transfer from wing tank to wing tank) be turned off?
On Takeoff
The minimum fuel feed temperature (from collector tanks to the engines) is
5 Celsius
The minimum bulk fuel temperature is
-40 Celsius
Which of the following areas have overheat detection only?
Main Wheel Wells
Which of the following areas have fire protection?
Cargo bay
Which of the following areas have dual loop protection?
Engine pylons
(True or False) It is possible to send both engine Halon bottles into one engine.
True
What does a Fire Fail message indicate?
Failure of one of the fire loops on a dual loop system
(True or False) The aircraft must always be within 45 minutes of a suitable landing airport if cargo is carried in the cargo compartment.
True
How can the pilot tell if the Engine Fire Bottles has sufficient Halon for flight?
By completing the Engine Fire Bottle Test
By manually checking the bottle pressure gauge in the Aft Equipment Bay
(True or False) The APU will automatically blow the fire protection bottle if a fire is sensed in flight.
False
Which of the following does not occur when the Engine Fire Push button is selected?
Only on-side engine bottle is armed
What does a “Smoke” aural message indicate?
Smoke in the cargo bay
What type of compressor does the APU on the CRJ 200 utilize?
Centrifugal
During the APU start procedure, when should the starter cut out?
50% RPM
What happens when the PWR/FUEL button is pressed?
APU ECU is armed for start
APU air inlet door opens
XFLOW/APU fuel pump starts
After pressing the PWR/FUEL button, when can the Start/Stop button be pressed to start the APU?
After the APU IN BITE message disappears
During the APU start procedure, when does the ignition begin?
10% RPM
During the APU start procedure, how can you tell if the APU starter has cutout?
START light goes out on the Start/Stop switch
APU Start message goes away on ED2
On the ground, when will the APU shut itself down automatically?
RPM >107%
EGT >743°C
APU Fire
ECU Failure
In flight, when will the APU shut itself down automatically?
APU Fire
ECU Failure
