The term "CPL pilot" refers to someone who holds a Commercial Pilot Licence — the credential that allows you to fly aircraft for compensation or hire. It's the professional entry point into aviation, sitting above a Private Pilot Licence (PPL) and below the Airline Transport Pilot Licence (ATPL) that major airlines require.
If you're serious about a flying career, the CPL is where it actually begins. This guide covers what the licence authorizes you to do, the requirements to get it, how training works, and what comes after.
A Commercial Pilot Licence unlocks categories of work that a private pilot simply can't do legally. With a CPL, you can:
What a CPL doesn't automatically give you: the right to serve as captain of a multi-crew commercial airliner. For that, you need an ATPL (frozen or full). Most airline first officers hold a "frozen ATPL" — meaning they've passed all the ATPL theory exams but haven't yet accumulated the flight hours to convert to a full ATPL.
This is probably the most common confusion in commercial aviation training. Here's how they relate:
A CPL lets you fly commercially as a single pilot or in specific co-pilot roles. A frozen ATPL means you've completed all the ATPL theoretical knowledge exams and hold a CPL/IR — but you haven't yet hit the 1,500 flight hours needed to unlock the full ATPL. Nearly every cadet airline program produces frozen ATPL holders, not full ATPLs. You "unfreeze" the ATPL after accumulating hours in airline service.
Think of it this way: CPL training and ATPL theory exams are intertwined in most integrated programs. You study and sit the ATPL exams during your CPL training, which positions you as a frozen ATPL holder when you finish — making you eligible to apply as a First Officer at commercial airlines.
There are two primary training pathways. Which one fits depends on your timeline, budget, and how much flying experience you already have.
Integrated training programs take you from zero hours to frozen ATPL in roughly 18–24 months through a single flight school. You progress through PPL, instrument rating, multi-engine rating, and CPL in one continuous program designed to flow without gaps. These are full-time, expensive (typically £70,000–£100,000+), and preferred by airlines because the training is standardized and continuous.
The advantage: you're employable faster and have a recognizable training history that airline recruiters know how to evaluate. The disadvantage: the cost is substantial and usually requires financing or a training loan.
The modular route lets you build ratings one at a time, often while working. You get your PPL first, then add an Instrument Rating (IR), then your CPL, then your Multi-Engine Rating (MEP) and MCC. It's significantly cheaper if you spread it over time, but it takes longer (3–5+ years) and requires more self-management to stay on track.
EASA regulations allow CPL issuance with as few as 150 flight hours on the modular route (provided certain conditions are met). For CPL training specifics including structure, approved flight schools, and what's covered in each phase, see the full training guide.
Whether you take the integrated or modular route, you'll need to pass 14 ATPL theoretical knowledge exams (under EASA rules). The exam subjects above represent the core categories, though EASA further splits some into subcategories.
Pass marks are typically 75% per subject. You have a limited number of attempts per subject and a window of time to complete all exams. Failing to pass within the window means starting over in some subjects. This is why most trainees take ground school seriously — these exams aren't trivial.
Ground school can be taken as part of an integrated program or as a standalone distance-learning or classroom course before beginning flight training. Several online providers cover all 14 subjects. The key is consistent study across several months — you can't cram 14 subjects in a few weeks.
EASA CPL requirements (used across EU and many other countries including the UK post-Brexit via UK CAA, which mirrors EASA closely) set the following minimums:
In the United States, the FAA requires 250 total hours for a CPL. The UK CAA and EASA standards differ slightly from FAA — if you're training internationally, clarify which authority's requirements you'll be meeting before enrolling.
You'll need a Class 1 Medical Certificate to exercise CPL privileges commercially. This is more stringent than the Class 2 Medical a PPL requires.
The Class 1 Medical assesses cardiovascular health, vision, hearing, neurological function, and mental health. Some conditions that are acceptable for private flying disqualify applicants from commercial flight. Common issues that generate extra scrutiny: corrected vision beyond certain thresholds, color vision deficiencies (though this affects specific roles more than others), history of certain cardiac conditions, and some psychiatric diagnoses.
Get your Class 1 Medical assessment before committing significant money to flight training. It's the first thing you should do. Discovering a disqualifying condition after spending £30,000 on ground school and early flight training is a scenario to avoid entirely. Most aviation medical examiners (AMEs) can give you a realistic picture of your status at a first appointment.
Here's an honest breakdown. Costs vary significantly by country and flight school, but these ranges reflect current UK/EU pricing.
Financing is common. UK pilot loans, bank loans, and some airline cadet bonds (where the airline funds training in exchange for a work commitment) are all used. Research bond schemes carefully — repayment penalties if you leave the airline early can be steep.
What does an newly qualified CPL pilot actually do first? Airlines don't typically hire zero-hour commercial pilots as First Officers — most want 500–1,500 hours minimum and a frozen ATPL plus Instrument Rating.
Common first jobs after CPL qualification:
The typical path to an airline seat: CPL/IR + frozen ATPL → flight instructing or charter work to 500–1,000 hours → regional airline First Officer → major carrier after building further.
The ATPL/CPL theory exams are where many trainees struggle most. Flight training is intuitive in many ways; the theoretical exams are dense, technical, and require memorizing substantial volumes of regulatory and technical content.
A few things that consistently help: working through question banks (not just reading notes) from early in your ground school, using timed practice tests to simulate exam conditions, and grouping your weaker subjects for concentrated review rather than spreading revision evenly. Subjects like Navigation, Meteorology, and AGK (Aircraft General Knowledge) are consistently the heaviest in terms of content volume.
Don't overlook the Human Performance paper. It's shorter than the technical subjects but covers CRM, fatigue science, and cognitive factors that show up in practical scenarios too — not just exam questions.

During a sterile cockpit phase of flight, the pilot monitoring notices the pilot flying has missed a critical radio call from ATC. What is the most appropriate CRM action for the pilot monitoring to take?
Answer: C. Assertively and clearly state, "ATC called with a heading change," and verify the pilot flying heard.
Effective CRM requires assertive communication, especially for safety-critical information. During a sterile cockpit, communication should be limited to items essential for the safe operation of the flight. A missed ATC instruction is critical. The pilot monitoring has a duty to promptly and clearly bring this to the other pilot's attention to maintain situational awareness and ensure a safe outcome.
A Part 135 pilot deviates from operations specifications during an in-flight emergency. Under 14 CFR 135.19, what is the pilot's obligation after the flight?
Answer: B. Submit a written report to the FAA within 10 days of the deviation
14 CFR 135.19 requires a pilot who deviates from any rule during an emergency to submit a written report to the FAA Administrator within 10 days.
A pilot is operating an aircraft over a congested area of a city. According to regulations, what is the minimum altitude the pilot must maintain above the highest obstacle within a horizontal radius of 2,000 feet?
Answer: C. 1,000 feet
According to 14 CFR § 91.119, when operating over any congested area of a city, town, or settlement, or over any open-air assembly of persons, an aircraft must be flown at an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.
A commercial pilot hears another aircraft transmit 'PAN-PAN, PAN-PAN, PAN-PAN.' What should the pilot do?
Answer: B. Keep the frequency clear and listen for ATC instructions
Upon hearing a PAN-PAN urgency call, other aircraft should maintain radio silence on that frequency unless they can provide assistance, and follow ATC direction for handling.
