Hi, I bought backseat pilot "The whole Shebang"
All contents are good. It's organized.
One thing I want to say is, for the "Operation of Systems".
Currently, I'm working with PA-28R-200 which is Piper Arrow. Maybe somebody is another aircraft.
So my suggestion is If there are many versions of "Operatiog of Systems" for many aircrafts would be goooood!
