they come with a detailed flight operating manual that is written in a manner you can find the relative issues you need to know.
I don't agree, flight manuals do not list/discuss idiosyncrasies of aircraft, there could be a gap between info in the flight manuals and the practical skills needed to handle the aircraft. Also reading about something and actually doing it with confidence - two vastly different things, you can read
Stick and Rudder but this doesn't necessarily translate to improving your flying skills.
