1. Which of the following components is NOT part of the aircraft's
hydraulic system?
A. Hydraulic pump
B. Hydraulic actuator
C. Hydraulic reservoir
D. Pneumatic system
Answer: D) Pneumatic system
Rationale: A pneumatic system is distinct from a hydraulic system and
uses air, whereas a hydraulic system uses fluid to operate various
components.
2. What is the primary function of an aircraft’s ailerons?
A. To control pitch
B. To control yaw
C. To control roll
,D. To control altitude
Answer: C) To control roll
Rationale: Ailerons control the roll of the aircraft by creating different
amounts of lift on each wing.
3. The primary function of an aircraft’s pitot-static system is to
measure which of the following?
A. Airspeed
B. Altitude
C. Both airspeed and altitude
D. Engine power
Answer: C) Both airspeed and altitude
Rationale: The pitot-static system measures airspeed through the pitot
tube and altitude through static pressure sensors.
4. Which engine component is responsible for converting fuel energy
into mechanical power?
,A. Compressor
B. Combustion chamber
C. Turbine
D. Fan blades
Answer: C) Turbine
Rationale: The turbine extracts energy from the combustion gases and
converts it into mechanical energy to drive the compressor and other
engine components.
5. In which of the following conditions will an aircraft’s center of
gravity be too far aft?
A. Excessive fuel in the tail
B. Excessive weight in the nose
C. Empty fuel tanks
D. Empty aft cargo compartment
Answer: A) Excessive fuel in the tail
, Rationale: Placing excess fuel in the tail will shift the center of gravity
aft, potentially leading to instability.
6. The main purpose of the aircraft's electrical system is to:
A. Power the engines
B. Provide lighting and communication
C. Control the aerodynamics
D. Generate thrust
Answer: B) Provide lighting and communication
Rationale: The electrical system primarily powers non-propulsive
systems like avionics, lighting, and communication.
7. The hydraulic system of an aircraft is commonly powered by:
A. Air turbines
B. Engine-driven pumps
C. Electrical motors
D. Pneumatic systems
hydraulic system?
A. Hydraulic pump
