The Commercial Pilot Licence (CPL) is the credential that allows a pilot to be compensated for flying aircraft. Earning a CPL requires passing a rigorous written examination that spans air law, navigation and flight planning, meteorology, aerodynamics, aircraft general knowledge, flight operations, and human performance and limitations. Whether you are pursuing a Transport Canada CPL or working toward an FAA Commercial Pilot Certificate, thorough written exam preparation is essential before you sit the knowledge test.
This free CPL practice test PDF provides printable exam questions across all major subject areas tested on the commercial pilot written exam. Download it, print it, and study offline—on a flight layover, during ground school, or anywhere that works for you. The questions are designed to reflect the style and difficulty of actual CPL written test items so you can measure your readiness with confidence.
The CPL written examination is one of the most comprehensive knowledge tests in civil aviation. Both Transport Canada and the FAA require candidates to demonstrate mastery across a broad range of academic subjects before they can exercise commercial pilot privileges. Here is a detailed look at each major subject area.
Air law questions test your knowledge of the regulatory framework governing commercial flight operations. For Transport Canada CPL candidates, this includes the Canadian Aviation Regulations (CARs), particularly Parts I, VI, VII, and VIII. FAA candidates study Part 91 and Part 135 regulations, aeronautical charts, AIM procedures, and Notices to Air Missions (NOTAMs). Topics include pilot certification requirements, aircraft airworthiness, right-of-way rules, airspace classifications, and VFR/IFR flight rules. Commercial operations introduce additional regulatory complexity around crew duty times, carriage of passengers for hire, and maintenance release requirements.
Navigation is one of the most calculation-heavy areas of the CPL written exam. You must demonstrate proficiency in VFR navigation using topographic charts, dead reckoning, and radio navigation aids (VOR, NDB, GPS). Cross-country flight planning questions require you to calculate true airspeed, wind correction angles, groundspeed, time enroute, and fuel requirements. IFR navigation topics—including instrument approach plate interpretation, holding pattern entries, and departure procedures—are tested at the CPL level and become even more critical for the Instrument Rating that typically accompanies or follows the CPL.
A strong understanding of aviation meteorology is essential for safe commercial flight operations. The CPL written exam tests your ability to read and interpret METARs, TAFs, PIREPs, AIRMETs, and SIGMETs. You must understand the development and characteristics of frontal systems, thunderstorm formation and avoidance, clear-air turbulence, mountain wave, structural icing conditions, and fog types. Pressure altimetry questions require you to apply QNH/QFE corrections and understand density altitude effects on aircraft performance.
CPL aerodynamics questions go beyond the private pilot level. You need to understand lift and drag coefficient curves, the effect of flaps and high-lift devices, stall characteristics at various bank angles and load factors, spin entry and recovery, and the aerodynamic factors affecting multiengine aircraft performance. Stability and control questions cover longitudinal, lateral, and directional stability, as well as the effects of CG position on handling qualities and safety margins.
This section covers powerplant systems (piston and turbine), fuel systems, hydraulic systems, electrical systems, pressurization and oxygen systems, and flight instruments. You must understand how each system operates, the indications of normal and abnormal operation, and the appropriate pilot actions for common failure modes. Questions on pitot-static instruments, gyroscopic instruments, and glass cockpit displays are common at the CPL level.
Transport Canada requires a minimum of 200 total flight hours for CPL issuance, including specific cross-country and night flying requirements. The written exam (STAAIR for CPL) must be passed with a score of at least 60%. The FAA Commercial Pilot Certificate requires 250 total hours and a passing score of 70% on the FAA Commercial Pilot Knowledge Test (PAR). Both regulatory authorities require a Class 1 medical certificate for CPL privileges. Candidates pursuing an ATPL (Airline Transport Pilot Licence) will build on CPL knowledge with additional study in multi-crew operations and advanced instrument procedures.
Human performance questions cover the physiological and psychological factors that affect pilot performance. Key topics include hypoxia types and symptoms, hyperventilation, spatial disorientation and its illusions, vestibular system limitations, visual illusions on approach, fatigue and circadian rhythm disruption, and the effects of alcohol and medication on pilot performance. Decision-making models such as DECIDE and Threat and Error Management (TEM) are also tested at the commercial level.
