About the FAA Sport Pilot Airplane Knowledge Test Exam

Sport airplane decisions depend on connecting aircraft behavior with operating conditions. The practice topics include recognizing how reduced airspeed affects aileron effectiveness, anticipating handling changes when center of gravity shifts aft, and using trim to relieve control pressure. Instrument and equipment questions address magnetic-compass indications, stall warning, and the emergency locator transmitter’s role. Weather interpretation includes understanding ceiling reports and seeking current information before departure. At non-towered airports, pilots need to monitor radio calls and build awareness of nearby traffic; during crosswind taxi, control inputs help limit wind effects on the airplane. These concepts support practical tasks such as assessing aircraft readiness, interpreting conditions, maintaining control, and making informed choices before and during a flight.

Sample Practice Questions

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

Question 1

What is the main purpose of an airplane’s stall warning system?

  1. ATo indicate that the airplane has exceeded its maximum operating speed
  2. BTo alert the pilot of an approaching stall so corrective action can be taken
  3. CTo automatically lower the landing gear when airspeed becomes low
  4. DTo measure the airplane’s angle of descent
Show answerCorrect answer: B

A stall warning system is designed to provide an alert before the wing reaches its critical angle of attack and stalls. The pilot should respond using the aircraft’s approved procedures and training.

Question 2

What does a standard aircraft magnetic compass indicate?

  1. ATrue direction, corrected automatically for local variation and deviation.
  2. BMagnetic direction, subject to errors from variation, deviation, and aircraft motion.
  3. CGround track over the Earth, regardless of wind.
  4. DHeading only when the airplane is in a coordinated turn.
Show answerCorrect answer: B

A magnetic compass aligns with Earth’s magnetic field and indicates magnetic direction. Variation, aircraft magnetic interference (deviation), and motion-related errors can affect its indication; it does not directly show ground track.

Question 3

A pilot hears an unfamiliar aircraft making a radio call near a non-towered airport. Which practice best helps maintain awareness of nearby traffic?

  1. ATransmit concise position and intention reports on the published CTAF and listen between calls
  2. BRemain silent unless another aircraft directly addresses the pilot
  3. CUse the emergency frequency for routine traffic reports
  4. DMake continuous transmissions so no other aircraft can use the frequency
Show answerCorrect answer: A

At a non-towered airport, pilots commonly use the published Common Traffic Advisory Frequency to announce position and intentions and to listen for other traffic. Calls should be concise and should not block the frequency.

Question 4

What does a weather report of a ceiling of 1,500 feet refer to in the usual aviation weather meaning?

  1. AThe height above ground of the lowest broken or overcast cloud layer
  2. BThe highest altitude at which visibility is unrestricted
  3. CThe height above sea level of the airport elevation
  4. DThe vertical distance between two cloud layers
Show answerCorrect answer: A

A ceiling is the height above ground level of the lowest broken or overcast layer, or vertical visibility into an obscuration. It is an important factor when assessing visual-flight conditions.

Question 5

A pilot is taxiing in a strong crosswind. Which control-input principle helps reduce the chance of the wind lifting a wing or affecting the tail?

  1. APosition the flight controls to oppose the wind, following the airplane’s recommended crosswind taxi guidance
  2. BHold the controls neutral at all times
  3. CUse full nose-up elevator regardless of wind direction
  4. DTurn the ignition switch off while moving
Show answerCorrect answer: A

Crosswind taxi control positioning helps keep the airplane’s wings and tail from being lifted or disturbed by the wind. The correct inputs depend on wind direction and airplane configuration, so the pilot should use the aircraft’s guidance and standard control-positioning practices.

Question 6

An airplane’s weight is unchanged, but its center of gravity is moved toward the aft limit. Which general effect should the pilot expect?

  1. AGreater longitudinal stability and stronger nose-down tendency
  2. BReduced longitudinal stability and potentially less effective stall recovery
  3. CA higher stall speed in all configurations
  4. DNo change in stability or handling
Show answerCorrect answer: B

An aft center of gravity generally reduces longitudinal stability and can make stall recovery more difficult. The aircraft must remain within the approved center-of-gravity limits.

Question 7

A pilot notices that the airplane’s ailerons feel less effective as the airplane slows during an approach. What is the best aerodynamic explanation?

  1. ALower airspeed reduces the airflow over the control surfaces, reducing their effectiveness
  2. BLower airspeed increases dynamic pressure over the control surfaces
  3. CAileron effectiveness depends only on engine RPM
  4. DThe vertical stabilizer is blocking airflow to the ailerons
Show answerCorrect answer: A

Control-surface effectiveness depends substantially on airflow and dynamic pressure. As airspeed decreases, the airflow over the ailerons weakens, so they produce less rolling control for a given deflection.

How to use this practice test

Access is free. A session draws up to 20 random questions from the 50-question practice bank and displays results afterward. Use each result to identify concepts to revisit, such as weather reports, flight-control effects, aircraft equipment, or airport traffic awareness.

Preparation tips

  • For questions on center of gravity, distinguish the effect of an aft shift from a change in aircraft weight, and connect the shift to stability and handling.
  • Review how airspeed affects control-surface effectiveness, and relate aileron response to the need for appropriate speed during approach.
  • Practice interpreting ceiling reports and compare an earlier weather briefing with updated information obtained close to departure.
  • For non-towered airport scenarios, consider radio monitoring alongside visual traffic scanning; for crosswind taxi questions, apply the appropriate control positioning for wind direction.
  • Separate the functions of the magnetic compass, stall warning system, trim system, and ELT so each piece of equipment is matched to its purpose.
