EASA ATPL Exam Difficulty Ranking by Subject in 2026
Ranking the 13 EASA ATPL Exams by Difficulty
The EASA ATPL theoretical knowledge examinations are widely considered the most demanding pilot exams in the world. Covering 13 subjects with over 14,000 questions in the central question bank, candidates must pass all exams within an 18-month sitting period with a minimum score of 75% per subject.
Knowing which subjects are hardest helps you allocate study time effectively and choose the optimal exam order. This ranking is based on official pass rate data, student surveys, and instructor feedback from major flight schools across Europe.

Why General Navigation Is the Hardest
General Navigation consistently has the lowest pass rate for several reasons:
- Complex calculations -- Grid navigation, convergency, conversion angle, and rhumb line vs great circle problems require strong mathematical skills
- Mental arithmetic under pressure -- Many questions involve multi-step calculations with no calculator allowed
- Map reading and plotting -- Questions require interpreting Lambert conformal and Mercator projections
- Compass theory -- Deviation, variation, dip, and acceleration errors confuse many students
How to Conquer General Navigation
- Master the 1-in-60 rule and practice mental math daily
- Draw diagrams for every navigation problem -- visual learners retain spatial concepts better
- Work through at least 500 practice questions before the exam
- Study convergency and conversion angle until you can explain them to someone else
The Radio Navigation Challenge
Radio Navigation is the second hardest because it combines:
- Technical knowledge -- Understanding how VOR, DME, ILS, GPS, and inertial navigation systems work at a component level
- System limitations -- Knowing the specific range, accuracy, and error characteristics of each navigation aid
- RNAV and PBN -- Performance-based navigation concepts are increasingly complex and heavily tested
- Integration -- Questions often combine multiple nav aids in realistic scenarios
Subject-by-Subject Study Tips
Hard Subjects (Ranks 1-6)
- General Navigation: Practice calculations daily. Use the [Rotate question bank](/) for timed practice sessions.
- Radio Navigation: Create system comparison tables. Draw block diagrams of each nav aid.
- Meteorology: Learn weather patterns visually. Sketch frontal systems, jet streams, and pressure patterns.
- Flight Planning: Practice fuel calculations until they become automatic. Know ICAO flight plan format.
- Principles of Flight: Focus on understanding rather than memorization. Draw force diagrams for every scenario.
- Aircraft General Knowledge: Break this massive subject into systems. Study one system per week.
Medium Subjects (Ranks 7-10)
- Instrumentation: Link each instrument to the physics behind it. Understand pitot-static, gyroscopic, and electronic instruments.
- Mass and Balance: Practice CG calculations with different aircraft types. This subject rewards repetition.
- Performance: Learn the graphs and tables. Most questions require reading performance charts accurately.
- Operational Procedures: Focus on ICAO procedures, fire and smoke protocols, and contaminated runway operations.
Easy Subjects (Ranks 11-13)
- Air Law: Memorization-heavy but straightforward. Focus on ICAO Annexes, pilot licensing rules, and airspace classifications.
- Human Performance: Apply common sense with a medical/psychological framework. Study fatigue, stress, and decision-making models.
- Communications: Know standard phraseology and procedures. Practice with realistic ATC scenarios.
Optimal Exam Order Strategy
Strategy 1: Easy First (Confidence Builder)
Start with Communications, Human Performance, and Air Law to build momentum. Then tackle medium subjects. Save hard subjects for when your study skills are sharpest.
Best for: Students who need early wins to stay motivated.
Strategy 2: Hard First (Front-Load Risk)
Start with General Navigation, Radio Navigation, and Meteorology. If you fail one, you have more time in your 18-month window to retake it.
Best for: Disciplined students who want to eliminate risk early.
Strategy 3: Related Subjects Together
Group related subjects to maximize knowledge overlap:
- Navigation block: General Nav + Radio Nav + Flight Planning
- Technical block: AGK + Instrumentation + Principles of Flight
- Operations block: Met + Ops Procedures + Air Law
- Light block: Human Performance + Communications + Mass and Balance + Performance
Best for: Most students. This is the approach recommended by most ATPL ground schools.
Time Management Across All 13 Exams
| Phase | Duration | Subjects | Weekly Hours |
|---|---|---|---|
| Phase 1 | Months 1-3 | Navigation + Radio Nav | 20-25 |
| Phase 2 | Months 3-5 | Met + Flight Planning + POF | 20-25 |
| Phase 3 | Months 5-7 | AGK + Instrumentation + Performance | 15-20 |
| Phase 4 | Months 7-8 | Air Law + Ops + HP + Comms + M&B | 15-20 |
| Buffer | Months 9-10 | Retakes if needed | As needed |
Total estimated study time: 800-1,000 hours for all 13 subjects.
The Bottom Line
The EASA ATPL exams are a marathon, not a sprint. Success comes from consistent daily study, strategic exam ordering, and targeted practice on weak areas. Do not underestimate General Navigation and Radio Navigation -- they have ended more ATPL attempts than any other subjects.
