Naturally, you’re going to find that some ATPL exams are easier than others and, if you’ve already started revising, then we’re sure that you’re already finding that you are enjoying some modules more than others. However, there are some ATPL exams that many widely agree are more difficult than others, including:
- Performance
- Meteorology
- General Navigation
- Principles of Flight
- Human Performance

In addition, out of all of the ATPL exams, the Principles of Flight module is considered by many to be the most difficult of all the ATPL exams. This is because, in this exam, you’ll need to prepare for it by learning how airplanes fly, including being comfortable with, and having a comprehensive knowledge of the main forces that can impact the aircraft while mid-flight, including weight, thrust, drag, and lift.
Are ATPL exams hard?
If you want to gain your ATPL or Airline Transport Pilot License, then you’ll first need to conduct a series of exams in order to successfully gain it! Generally speaking, some people will find certain ATPL exams easier than others, and this will depend mainly on your natural strengths and weaknesses.
However, the good thing about each ATPL exam is that they each follow the standard exam process structure as what you’ll have already experienced in your prior education studies. Therefore, regardless of which ATPL exam you take, the main struggle you’ll likely face is stress.
It’s also worth noting that ATPL exams have changed over the past couple of years. Initially, all ATPL exams were originally conducted in a multiple-choice format. However, as of right now, many ATPL exams are now conducted in a question and answer format, which means that you’ll likely find yourself needing to spend more time preparing for these types of questions, as you will need to provide a long-form answer without any visual prompts, or help from the multiple-choice answers.
Therefore, to make sure that you give yourself the best chance of success, we recommend using a variety of textbooks and flashcard ques to help you properly prepare for the exams.

Is ATPL theory hard?
If you have plans on becoming a pilot (whether private, commercial, or cargo) then the good news is that, so long as you have a basic understanding of maths and science, then there is no reason why you shouldn’t be able to pass your ATPL tests and acquire your license.
As a matter of fact, most budding pilots who have gone through the ATPL process comment on how the hardest part of the course is the sheer amount of material to work through. In total, you will need to learn and retain information across 14 different modules, and then apply all of the knowledge you have acquired to the written exams.
This isn’t impossible, but it will require dedication and determination to see the course through, which is something to keep in mind when deciding whether or not you want to become a professional pilot, especially as the process is both lengthy and costly.
