Frequently Asked Questions
What format is the question bank in?
A single bookmarked PDF file (approx. 10 MB). You can open it on any device — computer, tablet, or phone — using any PDF reader.
Are the correct answers included?
Yes. Every question has the correct answer highlighted in green with a checkmark, so you can study and self-test effectively.
How quickly will I receive the download link?
Immediately after payment is confirmed. The link is sent to your email and is valid for 12 hours. If you have any issues, contact us at info@part66online.com.
Is this different from the online quizzes?
The question bank contains the same questions as our online platform, but in a convenient offline PDF format. It's perfect for studying on flights, in the hangar, or anywhere without internet. The online subscription adds interactive quizzes, the Intelligent Progress Center — which reads how you answer, ranks your weakest syllabus chapters and tells you which one to drill next — and the community Q&A, so the PDF gives you the questions and the subscription tells you where to spend them.
Does it include the UK CAA Module 10?
Yes. Alongside the 18 EASA Part-66 modules, the PDF has a section for the UK CAA Part-66 Module 10 (Aviation Legislation), placed after EASA Module 10: 536 questions written to UK law for candidates who sit the UK paper. It has its own bookmark, like every module.
Can I print it?
Absolutely. The PDF is formatted for A4 paper with clean typography. You can print specific modules or the entire bank.
