In the previous article, we already mentioned the 7 easiest ATPL exams and their passing rates. Despite the fact that none of the subjects can be called “easy,” some are thought to be easier because of how frequently they are passed and what is tested. Now, let’s take a look at the 5 hardest ATPL exams.
Meteorology
- Number of Questions: 84
- Exam Duration: 2 hours
- Difficulty: Medium to Hard
- 81% of papers passed

Meteorology is the study of the air environment and how different weather, cloud and atmospheric conditions, can affect flight operations. Although some of the material (e.g. frontal systems or TAFs) should be quite easy to tackle, the global weather may seem a pain to get through because sometimes it gets impossibly hard to understand the logic behind what you are taught in this module. It takes a solid commitment to studying to get through this one.

Principles of Flight (Aeroplane)
- Number of Questions: 46
- Exam Duration: 1 hour 30 mins
- Difficulty: Hard
- 76% of papers passed
The Principles of Flight exam focuses on the forces acting on an aircraft, requiring a solid grasp of formulas and math. The syllabus, written at a university level, often feels overly complex, even for degree-level aerodynamicists. Practicing question banks is essential to align with EASA’s approach to problem-solving.

General Navigation
- Number of Questions: 55
- Exam Duration: 2 hours 15 mins
- Difficulty: Medium to Hard
- 70% of papers passed
General Navigation covers essential navigational skills like chart reading, plotting, and speed calculations. The subject is challenging, but consistent practice helps build speed and accuracy. Aim for 90-95% in practice tests to ensure strong results under exam pressure.

Performance (Aeroplane)
- Number of Questions: 45
- Exam Duration: 2 hours
- Difficulty: Hard
- 67% of papers passed
Performance is a crucial subject for real-life airline operations, focusing more on understanding aircraft performance principles than reading graphs. While graphs and tables remain, they now emphasize modern jet transports over piston aircraft.

Flight Planning and Flight Monitoring
- Number of Questions: 42
- Exam Duration: 2 hours
- Difficulty: Hard
- 65% of papers passed
For this subject, you’ll need to learn about the various rules and factors required when planning and flying a route. Be ready to perform all the calculations needed for flight including the cruising level, speed, fuel, and ground clearance.
Similar to General Navigation, at first it might seem impossible to finish the exam in the allotted time – but be patient, practice makes perfect. Aim for 90% to 95% in Airhead.
