One of the biggest challenges of advancing into bigger equipment is learning new systems. Let's build a thread where we can share tips so that we'll know our airplanes as well as we wish we knew Gemma Atkinson's body (personal preference )
EMB-120 school was months ago, but these things seemed to help:
1) Start with general information and limitations, then get into the tough stuff.
2) Look over the systems diagrams. Think about the big picture - what's really going on - and draw your own diagrams that simplify the information
3) After you learn how the systems work when everything is going as planned, go back through a few times and ask yourself what happens if a certain component malfunctions. This is the really important stuff that will be tested on the checkride
4) Learn what will trigger each annunciator
That's all I can think of for now, feel free to contribute!
