Questions
@costas1979 it's says on your DLR CBT documentation, read in the document called basic knowledge it's says the following:
Tests for Aeronautical Knowledge during the DLR assessment
Your proficiency will be checked during computer assisted testing with a multiple choice test aiming at systems, meteorology, air law, navigation, instruments and human performance limitations. We do not provide a specific Aeronautical Knowledge CBT programme for you to train with. If you feel you have to brush up in aeronautics you need to do this with your own material. Additionally, expect aeronautical problems also to be discussed during your interview.
Hope this clarifies your doubts.
