This aircraft I mention here does not contain a virtual cockpit.... but the elaborate panels by Matthias Lieberecht for the wonderful models done by Jon Murchison make this the best freeware aircraft that I have found yet.
There are a number of versions of the BAe-146 series available there. The earlier ones have less "features". Some contain interesting and creative effects such as ground support vehicles and animated cargo loading on the ground when it is "cold and dark". And the pilots disappear at the right time too

.
The version two panels allow a pretty good "cold" start up.....but you can also just do the autostart thing.
The version three panels (nice!) do not allow anything BUT a "cold and dark" cockpit at start up. He has pretty much replaced the default Microsoft internal coding functions completely. You have to bring everthing up from cold... and it takes a close eye on the checklists

. These panels come with a 100 page pdf manual.....if that gives you any idea of the complexity and adherence to realism. If you want to just "jump in and fly".... not the panel you want!
You can put the version three panels in any of the other craft. Or the version two ones in any.
I have been flying this aircraft as my prime aircraft for a long time. Nice mid-range STOL four engine jet.
