FAA Commercial Pilot Gyroplane Knowledge Test Practice Test

The FAA Commercial Pilot Gyroplane Knowledge Test (CRG) concerns aeronautical knowledge applied to gyroplane flight. Practice-bank questions sample rotor and propeller functions, control inputs near the surface, landing-approach judgment, weather hazards, chart use, and traffic-pattern entry. These subjects connect aircraft behavior with the decisions a pilot makes during local and cross-country operations.

About the FAA Commercial Pilot Gyroplane Knowledge Test Exam

Gyroplane handling depends on understanding how airflow drives the rotor in normal powered flight and how the propeller provides thrust. Pilots need to recognize the roles of the vertical stabilizer and other control surfaces, anticipate the effects of abrupt inputs near the ground, and protect an exposed rotor when the aircraft is parked in strong wind. Operational judgment also includes obtaining a weather briefing, interpreting current charts, and anticipating turbulence or downdrafts on the lee side of a ridge. During approach and airport operations, pilots must assess height using multiple visual references and join an unfamiliar traffic pattern with awareness of other aircraft and local procedures. Together, these concepts support safer aircraft handling, route planning, and situational awareness.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

Why should a gyroplane pilot be cautious about abrupt control inputs close to the ground?

  1. AThey may leave insufficient height and time to recognize and recover from an upset
  2. BThey increase the aircraft’s radio range
  3. CThey automatically increase rotor blade length
  4. DThey prevent the pilot from using the rudder
Show answerCorrect answer: A

Near the ground, there is little margin for correcting an upset or excessive maneuver. Smooth, deliberate control inputs help preserve control and allow appropriate response time.

Question 2

What is the main purpose of a gyroplane’s vertical stabilizer during flight?

  1. ATo help provide directional stability
  2. BTo increase rotor RPM during descent
  3. CTo control engine mixture
  4. DTo reduce the aircraft’s weight
Show answerCorrect answer: A

The vertical stabilizer helps resist unwanted yaw and contributes to directional stability. It does not control the engine or rotor RPM.

Question 3

A gyroplane’s rotor is driven by the airflow through it in normal powered flight. What best describes this rotor state?

  1. AAutorotation, with the rotor turning freely from aerodynamic forces
  2. BPowered rotation, with engine torque continuously applied to the rotor
  3. CLocked rotation, with the rotor held at a fixed pitch
  4. DReverse rotation, with the rotor turning opposite the airflow
Show answerCorrect answer: A

In normal gyroplane flight, the rotor is not driven by the engine; airflow through the rotor sustains its rotation in autorotation. The engine typically provides thrust through a separate propeller.

Question 4

What is the main function of a gyroplane’s propeller during ordinary powered flight?

  1. ATo provide thrust that moves the aircraft forward.
  2. BTo control rotor blade pitch directly during each revolution.
  3. CTo serve as the aircraft’s primary landing brake.
  4. DTo measure the rotor’s rotational speed.
Show answerCorrect answer: A

The propeller produces thrust, while the rotor provides most of the aircraft’s lift. The precise arrangement varies by design, but the propeller’s ordinary role is propulsion.

Question 5

When a gyroplane is parked outside in strong wind, what is a sound way to reduce the chance of rotor damage?

  1. ASecure the aircraft and restrain the rotor in accordance with the aircraft manufacturer’s instructions.
  2. BLeave the rotor free to turn so it can align itself with the wind.
  3. CTie a control surface tightly in the full-travel position.
  4. DPlace loose objects on the rotor blades to hold them down.
Show answerCorrect answer: A

Wind can cause an unrestrained rotor to turn or flap and potentially strike the airframe or nearby objects. Use approved securing procedures and suitable tie-downs, following the aircraft instructions.

Question 6

What is the primary reason for obtaining a weather briefing before a cross-country flight?

  1. ATo identify conditions that may affect the safety and feasibility of the route
  2. BTo determine whether the aircraft registration is current
  3. CTo establish the aircraft’s empty weight
  4. DTo replace the need for in-flight weather awareness
Show answerCorrect answer: A

A preflight weather briefing helps the pilot evaluate conditions along the route and at the destination, including hazards that could affect the decision to depart or the flight plan. Weather can change, so it does not replace continued awareness.

Question 7

Why should a pilot consult current aeronautical charts when planning a route?

  1. ACharts depict relevant airspace, navigation information, terrain, and airport data needed for route planning.
  2. BCharts guarantee that all depicted facilities will be operating on the flight date.
  3. CCharts replace the need to check temporary notices and weather.
  4. DCharts show the aircraft’s exact position without any navigation input.
Show answerCorrect answer: A

Current charts provide important route-planning information such as airspace boundaries, terrain, airports, and navigation references. They do not replace checking current weather or notices, and depicted information may still require verification.

How to use this practice test

The free practice session presents up to 20 randomly selected questions from a bank of 50. Use each question to check your understanding of gyroplane rotor behavior, aircraft control, weather and route planning, and airport operations. Results appear after the session so you can identify topics to revisit.

Preparation tips

  • Explain how airflow drives the gyroplane rotor in normal powered flight, and distinguish rotor function from propeller thrust.
  • Review the effects of abrupt control inputs near the surface and ways to secure or protect the rotor when parking in strong wind.
  • For route-planning practice, connect weather briefings and current chart details to terrain, airspace, and anticipated ridge-induced turbulence or downdrafts.
  • Practice evaluating landing height with more than one visual reference, then describe how to enter an unfamiliar airport’s traffic pattern while observing other traffic.
