ATPL Prerequisites: Complete Requirements and Eligibility Guide

Before you commit tens of thousands of euros and several years of your life to pilot training, you need to be sure you actually can become an airline pilot. That means checking age, medical fitness, language skills, legal background, and financial readiness early on.

This guide walks through the key prerequisites for EASA, FAA, and UK CAA pathways so you can realistically assess your eligibility and plan your route into professional aviation.

Why Prerequisites Matter

Regulatory and Safety Reasons

Aviation authorities don’t set requirements to make life difficult — they do it to protect passengers, crews, and you. If you don’t meet the basic standards, you won’t get a license, no matter how much you’ve already invested.

• If you overlook a disqualifying medical issue and only discover it halfway through training, you can easily lose €60,000–€150,000 with nothing to show for it.
• If your English or academic foundation is too weak, ATPL theory becomes a constant uphill battle.

Understanding the rules up front protects both your wallet and your career plans.

Financial and Timeline Planning

Some requirements are not instant:

• Initial Class 1 medical can take several weeks, especially if extra tests are needed.
• Background and security checks may take 1–3 months, depending on the country.

You want all of this sorted before you sign a training contract or relocate for a course.

Big Picture: Core ATPL Requirements

Regardless of authority, the end goal for an unrestricted ATPL looks very similar:

• Minimum age for the full ATPL (captain privileges): usually 21–23, depending on authority.
• Class 1 / First Class medical: the highest medical standard for commercial pilots.
• English proficiency meeting ICAO Level 4 or higher.
• A substantial amount of flight time (typically 1,500 hours for a full ATPL).
• Successful completion of ATPL theory and the required skill tests.

How and when you meet these criteria differs between EASA, FAA, and UK CAA — but the general direction is the same.

Age Requirements

EASA

Under EASA, you don’t get the full ATPL license immediately. You first obtain a CPL/IR/ME with completed ATPL theory (the so-called frozen ATPL), then “unfreeze” it later once you have enough experience.

Typical minimum ages:

• PPL: license issue from 17
• CPL: license issue from 18
• Frozen ATPL (CPL/IR/ME + ATPL theory): from 18
• Unrestricted ATPL: from 21, with the required flight experience (including multi-pilot hours)

In practice, most pilots reach the full ATPL in their mid-20s when they have built enough hours.

FAA (USA)

The FAA structure is similar, but with different labels:

• Private Pilot: from 17
• Commercial Pilot: from 18
• ATP (full Airline Transport Pilot certificate):
• Standard ATP: 23
• Restricted ATP (R-ATP): from 21, with specific university or military backgrounds

UK CAA

Post-Brexit, the UK kept a structure very close to EASA:

• PPL from 17, CPL from 18, ATPL from 21
• Requirements and terminology are almost identical to EASA, but under UK Part-FCL.

Practical Considerations

• Starting young (late teens / early 20s) gives you more career years and a longer return-on-investment period.
• Starting later (30s or beyond) is still possible, but you need to be realistic about health, retirement age (often 65), and payback time on training costs.

There is no official upper age limit for training — the medical will be the deciding factor.

Medical Requirements

Why the Medical Comes First

The Class 1 (or First Class) medical is your entry ticket to a professional flying career. Without it, no ATPL — full stop.

You should:

Always get your Class 1 medical before committing to expensive training.

If the authority later decides you’re not medically fit, all the money and time you’ve put into training is essentially lost.

Medical Classes

• EASA / UK CAA
• Class 1: required for CPL/ATPL
• Class 2: for PPL
• LAPL medical: lighter privileges only
• FAA
• First Class: for ATP / airline captains
• Second Class: for commercial operations
• Third Class: for private flying

For an airline career, you’re aiming at EASA/UK Class 1 or FAA First Class.

What Class 1 Typically Assesses

The details vary slightly by authority, but core elements are similar:

• General health: cardiovascular, respiratory, neurological, metabolic, musculoskeletal, etc.
• Vision:
• Correctable to normal (within defined limits, typically around +5.00 to -6.00 diopters)
• Good near and intermediate vision
• Adequate colour perception (or proven safe colour vision)
• Hearing:
• Good hearing at conversational range and within defined audiometric limits.
• Cardiovascular health:
• Blood pressure within acceptable range
• ECG screening, especially as you get older or if risk factors are present
• Laboratory tests:
• Urinalysis, blood tests, and further work-ups if anything looks off.

Existing conditions like diabetes, heart disease, epilepsy, severe mental health disorders, or significant vision problems don’t automatically mean “no”, but they do require careful evaluation and sometimes impose restrictions — and in some cases will prevent you from obtaining a Class 1.

Validity

• EASA/UK Class 1
• Up to 12 months validity when younger
• Reduced to 6 months beyond certain ages (e.g. 60+)
• FAA First Class
• For ATP operations: 12 months if under 40, 6 months if over 40
• After that, it “downgrades” to the equivalent of a lower class for non-ATP flying.

The Medical Process in Practice

1. Find an approved AME (aeromedical examiner) from your authority’s list.
2. If you have any health concerns, consider an informal pre-consultation before the official exam.
3. Book an initial Class 1 and bring:

• ID
• Glasses/contact lens prescription if applicable
• Full history of medications and previous illnesses

4. Complete the exam and any extra tests requested.

1. Receive:

• Immediate approval,
• a deferral (more tests needed), or
• a denial (does not meet standards).

In many “borderline” cases, it’s not black and white — additional tests and reports from specialists can sometimes help you obtain a medical with conditions or limitations.

If you cannot obtain a Class 1, you can still fly privately (Class 2/LAPL) or explore non-pilot roles in aviation.

Educational Background

Formal Requirements

Most authorities do not demand a specific school-leaving certificate in their regulations. However:

• ATPL theory is maths- and physics-heavy.
• English is essential for exams and training.

A solid secondary education with at least basic math and physics to age 16 is strongly recommended.

Reality in the Job Market

Even though you can become a pilot without a university degree, many airlines prefer or even expect candidates with higher education, especially in competitive markets.

For university-integrated programmes, the entry gate is the university’s admission criteria: grades, entrance tests, and English proficiency tests for international students.

Language Proficiency (ICAO English)

Aviation is conducted in English worldwide, so language is not optional.

ICAO Levels

• Level 6 – Expert: essentially native-level, valid indefinitely.
• Level 5 – Extended: advanced, valid for 6 years.
• Level 4 – Operational: minimum required for licensing, valid for 3 years.

Anything below Level 4 is not sufficient for professional operations.

How It’s Assessed

• During your skill test and radio work, or
• Via a dedicated language proficiency check with an approved examiner.

You’ll be evaluated on:

• pronunciation,
• grammar,
• vocabulary,
• fluency,
• comprehension,
• and how well you interact in non-standard situations.

If English isn’t your first language and you’re not yet at operational level, it’s worth investing in an aviation English course and regular practice with phraseology and plain-language communication.

Flight Experience Requirements (End Goal)

The full ATPL license is not issued immediately after training. It’s the end of a long journey:

EASA

To convert from a “frozen” ATPL to an unrestricted ATPL, you typically need:

• 1,500 hours total flight time
• A defined amount of multi-pilot and multi-engine experience
• Specific totals at night, in instrument flight, and as pilot-in-command

You’ll gather most of these hours after you’ve finished initial training and started working (for example as a first officer or instructor).

FAA

For a standard ATP:

• 1,500 hours total time, with defined sub-requirements.

For a Restricted ATP (R-ATP):

• Lower hour requirements (e.g. 750–1,250 hours) if you have:
• relevant military background or
• an aviation degree from an approved university.

These requirements sit on top of the usual CPL and IR training and are usually achieved by working as an instructor or in other commercial roles before joining an airline.

See EASA Licensing Process and FAA ATP Requirements for the detailed breakdown.

Legal, Security, and Residency Requirements

Background and Criminal Record

Authorities and airlines will look at your criminal history, especially for:

• violent or serious offences,
• fraud, drug trafficking, or security-related crimes,
• aviation or transport-related offences.

Minor traffic fines are usually not an issue; serious or repeated offences can be. Full honesty is crucial — failure to disclose can be taken more seriously than the original offence.

Security Checks

For access to airports, secure areas, and sometimes for training itself, you may need:

• a security background check,
• fingerprinting,
• airport ID passes.

In the US, international students also undergo TSA clearance before starting certain types of training.

Residency and Work Rights

• You do not need to be an EU or US citizen to train there, but you’ll need the correct visa (e.g. M-1 in the US).
• For airline jobs, work rights become critical. EU airlines generally prefer or require EU/EEA work permission; US airlines expect US work authorization.

---

Financial Prerequisites

Even if you meet all legal and medical criteria, you still need a realistic financial plan.

• Training costs for an ATPL path (including living expenses) often land between €80,000 and €150,000 in Europe — sometimes more in other regions.
• Many schools will ask for proof of funds or loan approval before they confirm a place on an integrated course.

A sensible approach:

• Secure funding for the full programme,
• Add a contingency buffer for exam retakes, extra hours, and delays,
• Keep a separate emergency fund for unexpected life events.

For a detailed cost breakdown and budgeting ideas, see ATPL Costs Breakdown.

Personal Suitability

Beyond the formal boxes to tick, there are “soft” prerequisites that make a big difference.

Physical and Lifestyle Factors

• Training involves long, intense days and considerable mental load.
• Later in your career, irregular working hours, time zones and night operations are normal.

A reasonably healthy lifestyle, decent fitness, and good sleep habits are less about regulations and more about long-term sustainability.

Mental and Cognitive Skills

Useful traits include:

• good spatial awareness,
• comfort with maths and technical concepts,
• strong attention to detail,
• the ability to multi-task and prioritise,
• calm decision-making under pressure.

Many cadet schemes run aptitude tests to measure exactly these skills, and you can practice similar test formats in advance.

Personality and Motivation

You’ll be working in a team environment with shared responsibility for safety. Airlines look for:

• professionalism,
• reliability,
• strong communication and teamwork skills,
• and a realistic, long-term motivation for the job.

Enthusiasm for flying is important, but it needs to sit alongside discipline and a professional attitude.

Timeline: Preparing Before Training

6–12 Months Before You Start

• Get your Class 1 medical (or at least a pre-assessment if you have concerns).
• Build a clear financial plan and secure funding.
• Research and visit flight schools, comparing integrated vs modular options.
• Check any visa or residency requirements if you plan to train abroad.

3–6 Months Before

• Enrol with your chosen school and confirm your start date.
• Arrange accommodation and estimate realistic living costs.
• Start light pre-study: basic aerodynamics, navigation concepts, and aviation English.

1–3 Months Before

• Finalise travel and housing.
• Buy essential equipment (headset, flight bag, basic tools).
• Get your personal life organised so you can actually focus on training once it starts.

Quick Prerequisites Checklist

Before you commit, you should be able to answer “yes” to at least the following:

• Age
• I meet the minimum age for the license(s) I’m targeting and my timeline makes sense for my career plans.
• Medical
• I hold (or have been pre-approved for) a Class 1 / First Class medical suitable for commercial training.
• Language
• My English is at least ICAO Level 4, or I have a clear plan and timeline to reach that level.
• Legal & Security
• I have no disqualifying criminal background and I’m eligible for required background and security checks.
• If I plan to train abroad, I understand the visa requirements.
• Financial
• I have a realistic budget, funding source, and contingency for my chosen training path.
• Academic & Cognitive
• My maths and physics knowledge is adequate, or I’m prepared to refresh these subjects.
• I understand what ATPL theory demands and I’m ready to put in the work.

Conclusion

ATPL prerequisites are less about ticking bureaucratic boxes and more about making sure you’re truly ready — medically, legally, financially, and personally — for a demanding professional training programme.

If you:

• secure your Class 1 medical early,
• confirm financial feasibility,
• meet the language and legal requirements,
• and prepare yourself academically and mentally,

you’ll enter training on solid ground and greatly reduce the risk of unpleasant surprises along the way.

From there, you can focus on what really matters: choosing the right training path, progressing through your EASA licensing journey or FAA ATP route, and building the skills and experience that will carry you into the right-hand seat — and eventually into the left.
