Starting from the point that this a "vintage" plane and is something amazing in FSworld...I think that to simulate perfectly the mouse, we need to modernize the navigation.From photos around the net i see that now the most 737-200 are equipped with FMS or the great old Garmin 155 TSO.And also complete the PDCS computer...for perfect simulation of the performances calculations...BTW, that's a great plane, yet near to perfect as it is.Cheers,
