Boeing 737 NG Diagrams

This is the most comprehensive most simple and easy way to not only to understand the system but also to learn how to operate the system and touch the controls before even going to the sim or the aircraft itself Wow this is a must for any one attempt to get typed on the gorgeous and beautiful Boeing 737-800 Thank you is not even enough You are well appreciated thank you for the good and beautiful work.

I bought this when I picked up my 737 type rating a few years back. It still serves as a great systems refresher before checkrides. There is something to be said for flipping switches on the app to see schematic changes vs just looking at a diagram.

I purchased this app for study, and now have used it successfully sorting a problem airborne; two thumbs up.
