Question 1

What is the primary function of a helicopter freewheel unit (overrunning clutch)?

To disconnect the rotor system from the engine in the event of an engine failure or during autorotation To lock the main rotor blades during high-speed engine start To automatically adjust tail rotor pitch in response to main rotor torque changes To vary the engine idle speed during ground warming up

Correct Answer:

To disconnect the rotor system from the engine in the event of an engine failure or during autorotation

Question 2

On a standard helicopter dual-needle tachometer, what do the two needles indicate?

Main Rotor RPM (R) and Engine RPM (E) Main Rotor RPM and Tail Rotor RPM Engine RPM and Transmission Oil Pressure Airspeed and Rotor RPM

Correct Answer:

Main Rotor RPM (R) and Engine RPM (E)

Question 3

What type of rotor hub allows individual main rotor blades to flap, drag (lead-lag), and feather?

Fully articulated rotor hub Teetering (semirigid) rotor hub Rigid rotor hub without any hinges Single-blade counterweighted rotor hub

Correct Answer:

Fully articulated rotor hub

Question 4

Why is a clutch necessary between the engine and the main rotor system in a piston-engine helicopter?

To allow the piston engine to be started without the heavy load of the rotor system To prevent the main rotor from exceeding its maximum continuous airspeed To reduce vibration during high-speed forward flight To convert engine rotary motion into hydraulic pressure

Correct Answer:

To allow the piston engine to be started without the heavy load of the rotor system

Question 5

What engine parameter is displayed on the Manifold Pressure (MAP) gauge in a piston-engine helicopter?

The absolute pressure of the fuel-air mixture in the engine intake manifold The exhaust gas pressure leaving the engine cylinder heads The hydraulic pressure supplied to the main rotor actuators The pressure inside the main transmission lubrication sump

Correct Answer:

The absolute pressure of the fuel-air mixture in the engine intake manifold
