FAQ

+Is this the real EASA question bank?

No. Exam questions are set by each authority or Part-147 organisation and are not published. AeroPass questions are written from Part-66 Appendix I and public FAA maintenance handbooks.

+Does one purchase cover other modules?

Yes. One purchase unlocks every EASA Part-66 B1.1 module in the app as it is released.

+Can I use a calculator?

Check with your exam provider. Most Part-66 exams do not allow calculators, so AeroPass questions use numbers you can work by hand.
