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.

+Is Module 4 the same for B1 and B2?

The topics are shared, but B2 is examined at a higher level. AeroPass follows the B1 level.
