FAA Recreational Pilot Airplane Knowledge Test Practice Test

The FAA Recreational Pilot Airplane Knowledge Test (RPA) covers aeronautical knowledge applied to recreational airplane flying. Practice-bank questions sample airport operations, traffic-pattern procedures, flight instruments, aircraft systems, basic aerodynamics, weather effects, and piston-engine operation. These topics connect cockpit indications and flight conditions with decisions a pilot makes before and during a flight.

About the FAA Recreational Pilot Airplane Knowledge Test Exam

Recreational airplane pilots need to interpret instrument indications, recognize abnormal or changing conditions, and apply safe operating procedures. The practice material includes airport-surface questions, such as understanding taxi instructions near a runway, and traffic-pattern questions about the base leg. It also samples use of the vertical speed and slip-skid indicators, transponder emergency code 7700, and the function of an alternator or generator. Aerodynamic and performance concepts include stall risk and the effect of high density altitude on a normally aspirated piston airplane. Weather-related material includes the Coriolis effect, while engine-operation questions address mixture leaning at cruise altitude. Together, these concepts support practical choices about aircraft control, system status, performance, and situational awareness.

Sample Practice Questions

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

Question 1

A pilot is instructed to taxi to a runway but is not explicitly cleared to enter or cross it. What should the pilot do?

  1. ATaxi onto the runway if no aircraft are visible
  2. BHold short of the runway and obtain the required clearance before entering or crossing
  3. CCross the runway while transmitting a position report
  4. DProceed onto the runway if another aircraft is holding nearby
Show answerCorrect answer: B

A taxi instruction alone does not authorize entering or crossing a runway. The pilot should hold short and obtain an explicit runway clearance before proceeding, while complying with applicable airport procedures.

Question 2

What does the transponder code 7700 indicate when selected by a pilot?

  1. AThe aircraft is operating under a visual flight plan
  2. BThe aircraft is experiencing an emergency
  3. CThe aircraft is requesting a radio frequency change
  4. DThe aircraft is entering a control zone
Show answerCorrect answer: B

Code 7700 is the general transponder emergency code. Pilots should also communicate the nature of the emergency to air traffic control when able.

Question 3

What information does an airplane's vertical speed indicator provide?

  1. AThe rate at which the aircraft is climbing or descending
  2. BThe aircraft's groundspeed over the terrain
  3. CThe engine's rate of fuel consumption
  4. DThe airplane's bank angle relative to the horizon
Show answerCorrect answer: A

The vertical speed indicator (VSI) shows the rate of climb or descent, usually in feet per minute. It responds to changes in static pressure and may lag behind the aircraft's actual vertical motion.

Question 4

In a standard traffic pattern, what is the purpose of the base leg?

  1. ATo align the aircraft with the runway centerline before landing
  2. BTo position the aircraft for the turn from downwind toward final approach
  3. CTo climb away from the airport after takeoff
  4. DTo check the engine's maximum power output
Show answerCorrect answer: B

The base leg is the segment between downwind and final. It positions the aircraft to turn onto final approach, where the aircraft is aligned with the landing runway.

Question 5

When an airplane is flying in a coordinated turn, what should the pilot generally observe on the slip-skid indicator?

  1. AThe ball centered
  2. BThe ball at the top of the instrument
  3. CThe ball fixed at the left edge
  4. DThe ball moving continuously from side to side
Show answerCorrect answer: A

A centered ball indicates that the airplane is coordinated, with no significant slip or skid. The pilot can use rudder pressure to correct a displaced ball.

Question 6

What is the purpose of an airplane’s alternator or generator during normal operation?

  1. ATo supply electrical power and recharge the battery
  2. BTo regulate fuel pressure to the engine
  3. CTo provide vacuum pressure for the brakes
  4. DTo control the airplane’s pitch attitude
Show answerCorrect answer: A

The alternator or generator supplies electrical power to the aircraft’s electrical system and replenishes the battery charge while the engine is running.

Question 7

What is a common effect of high density altitude on a normally aspirated piston airplane?

  1. AReduced engine, propeller, and wing performance
  2. BIncreased engine power and shorter takeoff distance
  3. CNo change in takeoff performance if the aircraft is lightly loaded
  4. DImproved climb performance because the air is less dense
Show answerCorrect answer: A

At high density altitude, thinner air generally reduces engine power, propeller efficiency, and wing lift for a given indicated airspeed. This can increase takeoff distance and reduce climb performance.

How to use this practice test

Practice is free. A session presents up to 20 random questions from the 50-question RPA practice bank, and results appear after the session. Use missed items to identify which concepts need another pass, such as runway clearance, instrument interpretation, density-altitude effects, or mixture management.

Preparation tips

  • Distinguish a taxi instruction from explicit clearance to enter or cross a runway; apply runway-hold procedures to the wording of each scenario.
  • Review what the vertical speed indicator and slip-skid indicator show, and connect each indication to aircraft motion or coordination.
  • Compare normal engine operation with high-density-altitude conditions, including the performance effects on a normally aspirated piston airplane and the reason for leaning the mixture in cruise.
  • Practice identifying traffic-pattern legs and explaining how a stall can develop as angle of attack increases.
  • Know the purpose of transponder code 7700 and the alternator or generator, and relate each to the situation in which a pilot uses or monitors it.
