I stumbled on a website that looks to be training software for real-world pilots. There is an app that explains every switch and panel interactively...if they had this for android I would not mind purchasing this even though I'm nowhere near for anything the like for a checkride ( I fly the 172 in real life) on the 737NG. Anywho...This is the link http://www.aerosim.com/products/checkride/b737 I was hoping to find a program that simulates the FMC to know how to use it properly away from the sim. I guess i have to keep searching.

Well...the FCOMs that came with the NGX do the same thing. :P

And they were free! ...sorta
