During my work experience I got to fly four jumpseat flights with Cimber Air (small danish regional airline), and they actually walked me through the FMC programming, startup and everything of an ATR-72. It was so great!!

So I bought the Flight/DreamFleet2000 ATR-72, tried to start it from cold, and program the FMC. And I pretty much succeeded within 20 minutes (with some help from the manual).
So that was very easy, two hours of pure fun flying with real ATR-72 pilots, and about 10 minutes of reading.

The Level-D 767 was another matter though!!

As I haven't ever seen a real life startup of a 767 (FMC programming is that different), it was very hard, so I headed for the manual. Read a lot, then read some more, then tried about 10 times, and failed, then finished reading, and still failed to start her up and fly her
properly.
So I got some help from an MD80 pilot I know, but since he isn't trained on the 767 he couldn't help me with everything, but he got me the real Boeing 757/767 CBT (Computer Based Training), which was extremely useful.
So I finally get familiar with the systems and I can now fly her properly. Very proud!
Me best advice is; Get some help. from a real airline pilot.
It's hard work learning this stuff, but worth it in my opinion.
