1.
What type of aircraft is the CRJ-550, and what makes it unique compared to other CRJ variants?
A. Turboprop with cargo focus
B. Regional jet with reduced seating capacity
C. Widebody jet
D. Military aircraft
Answer: B. Regional jet with reduced seating capacity
Solution:
The CRJ-550 is a modified CRJ-700 operated with 50 seats instead of the standard ~70. The
removed seats are replaced with extra baggage space, premium seating, and service areas,
allowing it to meet U.S. scope clause limits while offering upgraded passenger comfort.
2.
What engines power the CRJ-550?
A. Rolls-Royce Trent engines
B. GE CF34 turbofan engines
C. Pratt & Whitney PW4000
D. CFM56 engines
Answer: B. GE CF34 turbofan engines
Solution:
The aircraft uses General Electric CF34-8C5 engines, known for reliability in regional
operations. They are high-bypass turbofans, optimized for short to medium routes.
3.
What is the primary source of electrical power on the CRJ-550 during normal flight?
A. Batteries
B. Ground power unit
C. Engine-driven generators
D. Ram air turbine
Answer: C. Engine-driven generators
,Solution:
Each engine drives an AC generator, supplying the aircraft’s electrical system. Batteries are
backup, and the RAT (if installed) is emergency-only.
4.
Which system provides pressurization on the CRJ-550?
A. Hydraulic system
B. Bleed air system
C. Electrical compressors
D. Fuel pumps
Answer: B. Bleed air system
Solution:
Compressed air from the engines (bleed air) is routed through environmental control systems to
maintain cabin pressure and temperature.
5.
What is the function of the APU (Auxiliary Power Unit)?
A. Provides thrust during takeoff
B. Supplies electrical and pneumatic power on ground
C. Controls flight surfaces
D. Powers landing gear
Answer: B. Supplies electrical and pneumatic power on ground
Solution:
The APU allows independent operation without external power—used for engine start, cabin
conditioning, and electrical supply when engines are off.
6.
Which flight control surfaces are used for roll control on the CRJ-550?
A. Elevators
B. Rudder
C. Ailerons and spoilers
D. Flaps
,Answer: C. Ailerons and spoilers
Solution:
Roll is controlled primarily by ailerons, assisted by spoilers (spoilerons) to increase
effectiveness, especially at higher speeds.
7.
What is the purpose of the FADEC system on the CRJ-550?
A. Controls navigation
B. Manages engine performance automatically
C. Controls landing gear
D. Regulates cabin pressure
Answer: B. Manages engine performance automatically
Solution:
Full Authority Digital Engine Control (FADEC) optimizes engine thrust, fuel flow, and
protects against exceedances—reducing pilot workload and preventing damage.
8.
What happens if one hydraulic system fails?
A. Total loss of flight control
B. Backup systems maintain critical functions
C. Engines shut down
D. Aircraft depressurizes
Answer: B. Backup systems maintain critical functions
Solution:
The CRJ-550 has redundant hydraulic systems, ensuring essential controls (flight controls,
brakes, gear) remain operational even after a failure.
9.
Which navigation system is primarily used for modern en-route navigation?
A. VOR only
B. INS only
, C. FMS with GPS integration
D. Dead reckoning
Answer: C. FMS with GPS integration
Solution:
The Flight Management System (FMS) integrates GPS and other inputs to provide accurate
navigation, fuel planning, and route management.
10.
What is a key limitation pilots must monitor during climb?
A. Cabin lighting
B. Engine temperature and thrust limits
C. Seatbelt signs
D. Passenger count
Answer: B. Engine temperature and thrust limits
Solution:
Pilots must monitor EGT (Exhaust Gas Temperature) and thrust settings to avoid exceeding
engine limits, especially during high-power phases like climb.
11.
What is the purpose of the bleed air system besides pressurization?
A. Fuel transfer
B. Engine cooling only
C. Anti-ice and environmental control
D. Flight control movement
Answer: C. Anti-ice and environmental control
Solution:
Bleed air is used for wing/engine anti-ice, cabin pressurization, and air conditioning. It’s a
critical multi-use system—losing it affects several systems at once.
12.
What is the function of the yaw damper?
A. Controls pitch
B. Reduces Dutch roll
