1In a gyroplane in steady flight, the main rotor obtains its rotational energy primarily from what source?
A.An engine-driven transmission turning the rotor mast
B.Airflow passing upward through the rotor disc as the gyroplane moves forward
C.A tail rotor that drives the main rotor through a clutch
D.Stored energy in a flywheel attached to the rotor head
Explanation: A gyroplane rotor is always in autorotation: relative wind flows up through the rotor disc and keeps it spinning, unlike a helicopter whose rotor is engine-driven. Forward thrust comes from a separate propeller, while the freewheeling rotor produces lift.
2What FAA airman knowledge test code applies to the Private Pilot Rotorcraft–Gyroplane test?
A.PAR
B.PRH
C.PRG
D.RPG
Explanation: The FAA airman knowledge test for Private Pilot Rotorcraft–Gyroplane carries the test code PRG. It is a computer-based, multiple-choice exam administered through PSI.
3The minimum passing score on the FAA private pilot gyroplane knowledge test is:
A.65%
B.75%
C.80%
D.70%
Explanation: FAA airman knowledge tests, including the PRG, require a minimum score of 70% to pass. Scores below 70% require a retest after additional ground instruction.
4Dissymmetry of lift in a gyroplane rotor disc is caused by:
A.Uneven engine torque applied to the rotor mast
B.The advancing blade producing more lift than the retreating blade in forward flight
C.The retreating blade always stalling at cruise airspeed
D.Asymmetric fuel loading shifting the center of gravity
Explanation: In forward flight the advancing blade sees a higher relative airspeed than the retreating blade, so it tends to generate more lift. Blade flapping equalizes lift across the disc by changing each blade's angle of attack.
5Blade flapping in a gyroplane rotor system primarily compensates for:
A.Engine vibration transmitted to the rotor head
B.Loss of rotor RPM during the takeoff roll
C.Changes in barometric pressure with altitude
D.Dissymmetry of lift between the advancing and retreating sides of the disc
Explanation: As the advancing blade flaps up its angle of attack decreases, reducing lift, while the retreating blade flaps down and gains angle of attack and lift. This flapping action equalizes lift and keeps the rotor disc balanced in forward flight.
6A power push-over (buntover) in a gyroplane is most associated with:
A.A pushover to low or negative G that unloads the rotor, which can be aggravated by a high thrustline
B.Excessive rotor RPM during pre-rotation
C.An engine failure during a normal climb
D.Flying at maximum gross weight in calm air
Explanation: A buntover occurs when the rotor is unloaded by a forward pushover to low or negative G; the rotor can lose enough lift that the airframe pitches over. High-thrustline gyroplanes are more susceptible because thrust adds a nose-down pitching moment when the rotor is unloaded.
7To best protect against a power push-over, the pilot should:
A.Maintain maximum engine RPM at all times
B.Carry extra weight in the tail to lower the thrustline
C.Increase rotor blade pitch before each maneuver
D.Keep positive G loading on the rotor and avoid abrupt forward stick (pushover) inputs
Explanation: Maintaining a positive load on the rotor keeps it producing lift and resists buntover. Pilots should avoid abrupt nose-down (pushover) inputs, especially in high-thrustline designs, and reduce power before lowering the nose.
8The purpose of the pre-rotator on a gyroplane is to:
A.Provide forward thrust during cruise flight
B.Slow the rotor during the landing flare
C.Reverse rotor rotation for autorotation
D.Spin the rotor up to a sufficient RPM before the takeoff roll to shorten the ground run
Explanation: A pre-rotator (mechanical, hydraulic, or electric) brings the rotor up to speed before takeoff so the gyroplane can become airborne with a much shorter ground roll. Once flying, the rotor is sustained by airflow in autorotation and the pre-rotator is disengaged.
9Blade flapping at the rotor head is permitted by which component in a typical teetering gyroplane rotor?
A.A teeter (flapping) hinge or bearing at the rotor hub
B.A swashplate driven by the cyclic
C.A tail rotor gearbox
D.A collective pitch lever
Explanation: A two-blade gyroplane rotor commonly uses a teeter (underslung) hinge that lets the disc tilt as the blades flap, equalizing lift across the disc. This is a simple, robust solution for handling dissymmetry of lift.
10What controls the gyroplane's pitch and roll in flight?
A.Tilting the rotor disc through the cyclic control (the rotor head)
B.Engine throttle alone
C.A tail rotor pedal input
D.Differential aileron deflection on the rotor blades
Explanation: The pilot tilts the entire rotor head with the cyclic stick to change the direction of the rotor's lift vector, controlling pitch and roll. The rudder controls yaw, and the throttle controls thrust and climb performance.

About the FAA Private Pilot — Gyroplane (PRG) Exam

The FAA Private Pilot Rotorcraft–Gyroplane Knowledge Test (test code PRG) is the FAA airman knowledge test required on the path to a private pilot certificate with a rotorcraft–gyroplane category and class rating. It covers federal aviation regulations and airspace, gyroplane aerodynamics, aviation weather, gyroplane systems, performance and weight-and-balance, navigation, and aeromedical and decision-making factors. Because a gyroplane rotor is always in autorotation and unpowered, much of the test focuses on rotor behavior that differs from helicopters and airplanes.

FAA Private Pilot — Gyroplane (PRG) Study Tips from Top Performers

1Anchor every aerodynamics question on one fact: the gyroplane rotor is always unpowered and in autorotation, so an engine failure does not stop the rotor.
2Memorize the rotorcraft-specific rule that VFR fuel reserve is 20 minutes day and night, which differs from the airplane 30/45-minute reserves.
3Drill buntover and blowback together: blowback is the disc flapping aft as speed increases, while buntover is a rotor-unloading pushover hazard worsened by a high thrustline.
4Practice decoding full METAR and TAF strings out loud so wind, visibility, ceiling, and change groups become automatic.
5Sort missed questions by the seven content areas and re-study the weakest area before taking another mixed timed set.

Frequently Asked Questions

How many questions are on the FAA PRG knowledge test?

The official FAA Private Pilot Rotorcraft–Gyroplane (PRG) knowledge test contains 60 multiple-choice questions. This free practice bank provides 100 selected-response questions so you can drill well beyond the live test length and target weak areas.

What score do I need to pass the PRG test?

FAA airman knowledge tests, including the PRG, require a minimum score of 70% to pass. If you score below 70%, you must obtain an instructor endorsement certifying additional ground training before retesting.

How long is the FAA gyroplane knowledge test and where is it taken?

You have 2.5 hours to complete the 60-question computer-based PRG test, which is administered at PSI testing centers. Plan to bring government-issued photo identification and arrive early to check in.

Why is so much of the test about autorotation?

A gyroplane rotor is always in autorotation and is never powered by the engine in flight; airflow up through the disc keeps it spinning. Because this behavior differs from helicopters and airplanes, the FAA emphasizes rotor aerodynamics such as flapping, dissymmetry of lift, blowback, and buntover.

How much does the PRG knowledge test cost?

The PSI testing fee for the FAA airman knowledge test is approximately $175. Confirm the current fee with PSI when you schedule, since FAA testing fees are set by the testing provider and can change.

Are there 2026 changes to the FAA PRG test?

As of 2026 the FAA continues to administer the Private Pilot Rotorcraft–Gyroplane test under code PRG as a 60-question, 2.5-hour, 70%-to-pass computer-based exam through PSI. Always verify the current testing supplement and handbook references with the FAA before your test date.
