Here's how the CLS 747200 works! Not the best add on in terms of professional use: not all buttons are clickable, there are problems with the rudder and trim.... despite various fixes... Yet I must say the model and virtual cockpit look amazing. All in all it's a good aircraft, but I would have to recommend the no freeware Ready For Pushback 747200, way more realistic, but not as pretty. It's your call: nice looking or professional? I couldn't say.
What I do enjoy in this aircraft is the fully fonctionning INS system. It was a pleasure learning how to use the ancestor of the FMC, and load a flight plan "old style".
Hope you enjoy it!
