A good procedural sim is Airline Simulator 2 by nomissoft of Austria. I think you can still buy this from
justflight.com . If not visit the publisher's website at
nomissoft.com .
The main flight models are an MD-83 and a 747-400. Scenery is awful, but the flight models are very accurate and while the procedures are simplified for single person operation, the sim is still a challenge.
