QUESTIONS AND ANSWERS | WITH 100% CORRECT ANSWERS GRADED
A+ GUARANTEED SUCCESS
SECTION 1: DELTA AIRCRAFT SYSTEMS AND PERFORMANCE
1. Which hydraulic system on the Boeing 767-300ER powers the primary flight
controls, and what is its normal operating pressure?
A. System A, 3000 PSI
B. System B, 3000 PSI
C. System C, 5000 PSI
D. Standby System, 2500 PSI
[X] A. System A, 3000 PSI
Rationale: On the Boeing 767, the primary flight controls are powered by the left and
right hydraulic systems, designated as System A and System B, which both operate
at a nominal pressure of 3000 PSI.
2. In the event of a complete loss of both AC generators on an Airbus A330, what is the
primary source of electrical power for essential systems?
A. The Air-Driven Generator (ADG)
B. The Ram Air Turbine (RAT)
C. The Main Aircraft Battery
D. The Emergency Power Unit (EPU)
[X] B. The Ram Air Turbine (RAT)
Rationale: The Airbus A330, like many modern airliners, deploys a Ram Air Turbine
(RAT) to provide hydraulic and electrical power for essential flight controls and
instruments during a total generator failure.
,3. What is the primary function of the Wing Anti-Ice system on the Boeing 737 MAX?
A. To prevent ice formation on the leading edge slats and flaps
B. To de-ice the wing after ice has accumulated
C. To prevent ice buildup on the wing leading edge devices
D. To cool the wing surface during high-speed flight
[X] C. To prevent ice buildup on the wing leading edge devices
Rationale: The Wing Anti-Ice system on the 737 MAX uses bleed air to heat the
leading edge slats, preventing ice formation, which is critical for maintaining
aerodynamic efficiency.
4. Which component on the Boeing 787 Dreamliner is responsible for pressurizing the
cabin, replacing the traditional bleed air system?
A. Engine Bleed Air Valves
B. Electric Compressors
C. Auxiliary Power Unit (APU)
D. Cabin Air Conditioning Packs
[X] B. Electric Compressors
Rationale: The 787 is a bleedless aircraft, meaning it uses electric compressors to
provide air for cabin pressurization and air conditioning, improving efficiency.
5. What is the significance of the "EICAS" system on Boeing aircraft?
A. It provides navigation information to the flight management system.
B. It displays engine parameters and crew alerting messages.
C. It controls the autopilot and autothrottle functions.
D. It manages the aircraft's electrical power distribution.
[X] B. It displays engine parameters and crew alerting messages.
Rationale: EICAS (Engine Indication and Crew Alerting System) is a critical system
on Boeing aircraft that provides continuous display of engine performance data and
important alerts to the flight crew.
6. On the Airbus A320, what is the purpose of the Fly-By-Wire (FBW) system's "Normal
Law"?
A. It provides full authority over flight controls with no protections.
B. It limits flight envelope protections and provides consistent handling
characteristics.
C. It reverts to direct control laws for degraded situations.
D. It only controls the rudder and elevator.
[X] B. It limits flight envelope protections and provides consistent handling
characteristics.
, Rationale: In Normal Law, the Airbus FBW system provides full flight envelope
protection (e.g., preventing stall, overspeed) and consistent handling qualities,
reducing pilot workload.
7. What is the primary role of the Fuel Control Unit (FCU) in a jet engine?
A. To ignite the fuel-air mixture in the combustor
B. To regulate the flow of fuel to the engine based on thrust lever position
C. To cool the engine oil during operation
D. To transfer fuel from the wing tanks to the engines
[X] B. To regulate the flow of fuel to the engine based on thrust lever position
Rationale: The FCU, or its modern electronic equivalent (FADEC), is responsible for
metering the precise amount of fuel delivered to the engine combustor to achieve
the desired thrust.
8. What is the purpose of the "PACK" (Pneumatic Air Cycle Kit) system on a
commercial aircraft?
A. To provide hydraulic pressure for the landing gear
B. To generate electrical power for the cabin
C. To cool and condition bleed air for cabin pressurization
D. To provide thrust augmentation during takeoff
[X] C. To cool and condition bleed air for cabin pressurization
Rationale: The air conditioning packs take hot bleed air from the engines or APU and
cool it, remove moisture, and regulate its pressure to provide a comfortable and
safe cabin environment.
9. On the Boeing 777, what is the function of the "TAC" (Thrust Asymmetry
Compensator)?
A. To automatically apply rudder to counter yaw from an engine failure
B. To manage fuel distribution to maintain aircraft balance
C. To adjust the horizontal stabilizer for trim
D. To control the nose wheel steering on the ground
[X] A. To automatically apply rudder to counter yaw from an engine failure
Rationale: The TAC system on the 777 automatically applies rudder input to
counteract the yawing moment caused by an engine failure, reducing pilot workload
and improving safety.
10. What is the primary difference between a "Bleed Air" and a "Bleedless" aircraft like
the Boeing 787?
A. Bleedless aircraft do not have an APU.
B. Bleed Air aircraft use engine-compressed air for systems, while Bleedless use
