Free Helicopter Instructor License Exam Questions and Answers

Dissymmetry of lift in forward flight is compensated for mainly by:

• AA. Blade flapping
• BB. Using a larger tail rotor
• CC. Lowering the collective
• DD. Increasing rotor RPM

What is the correct recovery from retreating blade stall?

• AA. Increase collective and airspeed
• BB. Reduce collective, reduce airspeed and, if possible, descend to a lower altitude
• CC. Increase forward cyclic to gain speed
• DD. Apply aft cyclic and hold

Which TWO conditions are conducive to retreating blade stall? Choose two.

Select 2 answers.

• AA. Hovering in ground effect
• BB. Steep, abrupt turns
• CC. High gross weight
• DD. Cold, dense air at sea level

Translating tendency in a single main rotor helicopter with a tail rotor refers to the tendency to:

• AA. Pitch nose up with power
• BB. Lose altitude in turns
• CC. Drift laterally in the direction of tail rotor thrust during a hover
• DD. Spin the fuselage opposite the rotor

Immediately after an engine failure in cruise flight, what is the first action to enter autorotation?

• AA. Apply full right pedal
• BB. Pull the collective up to stop descent
• CC. Lower the collective to maintain rotor RPM
• DD. Call ATC

A helicopter is hovering with one skid on a slope and begins to roll. What is the correct recovery from dynamic rollover?

• AA. Apply full left pedal
• BB. Apply opposite cyclic abruptly
• CC. Pull in more collective
• DD. Smoothly and gently lower the collective

Which TWO conditions increase the likelihood of dynamic rollover? Choose two.

Select 2 answers.

• AA. Autorotation at cruise speed
• BB. High airspeed forward flight
• CC. One skid or wheel on the ground while hovering or landing on a slope
• DD. Rapid or excessive collective application

What is the typical sign of loss of tail rotor effectiveness (LTE)?

• AA. An unanticipated yaw that does not respond to normal pedal input
• BB. A steady vibration at 1/rev
• CC. A rapid drop in rotor RPM
• DD. A loss of engine power

What is the main hazard of the 'avoid' area of a height-velocity diagram?

• AA. The rotor blades overspeed
• BB. It is prohibited by airspace rules
• CC. Engine overheating occurs
• DD. A power failure there may not leave enough height or speed for a safe autorotative landing

Which TWO actions are used to recover from vortex ring state (settling with power)? Choose two.

Select 2 answers.

• AA. Apply aft cyclic and raise the nose
• BB. Reduce collective if altitude permits
• CC. Apply cyclic to gain forward airspeed
• DD. Raise the collective fully to arrest descent
