Commercial pilot license questions

ADVANCE FLYING ACADEMY

If you're preparing for your Commercial Pilot License (CPL) exam or just curious about what kind of questions you might encounter, here are some sample questions that cover key areas in ground school, flight knowledge, and practical flying. These questions can help you prepare for the theoretical and practical aspects of the CPL certification.

1. Aerodynamics & Flight Theory

Q1: What is the primary function of the ailerons on an aircraft?

A) Control pitch
B) Control roll
C) Control yaw
D) Control speed

Answer: B) Control roll

Explanation: Ailerons are control surfaces located on the wings of an aircraft that control roll, which is the aircraft's rotation around its longitudinal axis.

Q2: What is the effect of a high-speed stall on an aircraft?

A) Loss of lift and control authority
B) Increased lift due to airflow over the wing
C) Decreased drag
D) None of the above

Answer: A) Loss of lift and control authority

Explanation: A stall occurs when the angle of attack increases beyond the critical angle, causing airflow to separate from the wing surface and resulting in a loss of lift. High-speed stalls can be more dangerous because they occur at higher airspeeds and often go unnoticed until it’s too late.

2. Airspace and Regulations

Q3: What is the minimum visibility required for flight in Class C airspace under Visual Flight Rules (VFR) during the day?

A) 3 miles
B) 5 miles
C) 1 mile
D) 10 miles

Answer: A) 3 miles

Explanation: For VFR in Class C airspace during the day, the minimum visibility is generally 3 miles, and the pilot must remain clear of clouds.

Q4: In the event of a go-around after a missed approach, the pilot should:

A) Initiate a sharp climb immediately
B) Keep the landing gear down
C) Ensure the aircraft is in the correct configuration before climbing
D) Turn sharply to avoid obstacles

Answer: C) Ensure the aircraft is in the correct configuration before climbing

Explanation: A go-around should be conducted by first making sure the aircraft is in the correct configuration (e.g., flaps, power, and landing gear) before initiating a climb. This ensures the aircraft is safe and stable during the maneuver.

3. Navigation and Flight Planning

Q5: What is the purpose of ETOPS (Extended Twin-Engine Operations)?

A) Allowing twin-engine aircraft to fly over remote areas with extended diversion times.
B) Allowing single-engine aircraft to operate on cross-country flights.
C) Limiting the weight of aircraft flying over oceans.
D) Ensuring aircraft can fly in instrument conditions.

Answer: A) Allowing twin-engine aircraft to fly over remote areas with extended diversion times.

Explanation: ETOPS is a set of regulations that permits twin-engine aircraft to fly longer distances from suitable airports, typically over oceans or remote areas, by ensuring the aircraft can safely divert to an alternate airport within the specified time in case of an engine failure.

Q6: What is the meaning of the abbreviation "NDB" in navigation?

A) New Directional Beacon
B) Navigation Data Base
C) Non-Directional Beacon
D) Navigational Designator Box

Answer: C) Non-Directional Beacon

Explanation: An NDB is a type of radio transmitter that emits signals in all directions. It’s used in navigation, where pilots can use an aircraft’s ADF (Automatic Direction Finder) to determine the direction to or from the NDB.

4. Weather and Meteorology

Q7: Which of the following weather phenomena is most commonly associated with thunderstorms?

A) Clear skies and smooth air
B) Heavy precipitation, turbulence, and updrafts
C) Clear air and no wind
D) Wind shear and low visibility

Answer: B) Heavy precipitation, turbulence, and updrafts

Explanation: Thunderstorms are associated with severe turbulence, updrafts, and heavy precipitation. Pilots avoid flying through thunderstorms due to the potential for strong turbulence and other hazards.

Q8: What type of cloud formation is most likely to indicate severe turbulence?

A) Cirrus clouds
B) Cumulonimbus clouds
C) Stratus clouds
D) Altostratus clouds

Answer: B) Cumulonimbus clouds

Explanation: Cumulonimbus clouds are associated with severe weather, including turbulence, thunderstorms, and lightning. These clouds can produce dangerous conditions for pilots, including turbulence and updrafts.

5. Emergency Procedures

Q9: What is the first step to take if an engine failure occurs shortly after takeoff?

A) Attempt to restart the engine immediately.
B) Maintain airspeed and make a controlled descent.
C) Land on the nearest runway.
D) Perform a steep climb to avoid obstacles.

Answer: B) Maintain airspeed and make a controlled descent.

Explanation: In the event of an engine failure shortly after takeoff, it is critical to maintain airspeed to avoid a stall and ensure a controlled descent to a suitable landing area. Once the aircraft is under control, you can consider options for restarting the engine or choosing a landing site.

Q10: If you are experiencing carbon monoxide poisoning in the cockpit, what is the first action to take?

A) Open the cockpit vents and increase oxygen flow.
B) Turn off all electrical equipment.
C) Perform a controlled descent to land immediately.
D) Descend to a lower altitude to get more oxygen.

Answer: A) Open the cockpit vents and increase oxygen flow.

Explanation: Carbon monoxide poisoning can occur if there’s a leak in the aircraft’s heating system. The first step is to increase airflow by opening the cockpit vents and providing oxygen if available. This helps dilute the carbon monoxide and allows the pilot to make a safe landing.

6. Flight Operations and Safety

Q11: What is the purpose of a Pre-Flight Inspection?

A) To ensure that the aircraft is ready for flight, safe, and properly configured.
B) To check weather conditions for the flight.
C) To prepare the flight plan and ensure air traffic control clearance.
D) To adjust the aircraft's weight and balance.

Answer: A) To ensure that the aircraft is ready for flight, safe, and properly configured.

Explanation: A pre-flight inspection ensures that the aircraft is in good condition and meets all safety requirements before departing. This includes checking fuel levels, control surfaces, engines, and instruments.

Conclusion

These CPL sample questions cover a variety of areas, from aerodynamics and weather to airspace and emergency procedures. Preparing for these questions will help ensure you have the necessary knowledge and understanding to pass both the written exam and practical flight test required to obtain a Commercial Pilot License. Good luck with your training!
