Returning to industry. Need to refresh.
 

I'm returning to the industry after 10 years away from it. My knowledge level is quite rusty.

I'm looking for a professional study guide / course that focuses on the practical "need to know" stuff rather than the "nice to know" theoretical stuff.

Something professional and well presented for maximum efficiency in learning.

Anyone have any recommendations? Instrument flying/Weather are the big ones for me.

I'm a big fan of Rich Lengel's Everything Explained for the Professional Pilot. Definitely do a little research on it and make sure it fits your needs, but it cuts out all the superfluous text found in a lot of guides, manuals, handbooks, etc. and nicely outlines (and cross-references various regs, manuals, etc.) pertinent info to being a 91/121/135 pilot.

Skyhigh, is that you?
