The problem with Airlaw being there is no clear logic to a lot of it.
With mechanics you can trace this wire going to this lever going through this thingy here finally pulling over there.
There is logic, even visual as to how it works.
Air Law is like learning a foreign language, you just ahve to memorize the phrases till it starts making sense and your brain can actually make little connections between them.
Doing endless practice tests really help in this regard.
