Hi.Isn't the loadsheet and speed cards in the plane itself enough to make a succesful flight in the JS41? I see the point in TOPCAT with the big birds with flex t.o. and what have you, but the JS41? I guess rwy lenghts would be a little helpful, but everything else is covered in the plane and documentation itself (weights/speeds/approximate fuel consumption).________________________________________________________Ulrik KvistVATSIM Scandinavia ATC/Pilot
