Has anyone else noticed that version 1.2 seems to have a lot less range than the 1.0 or 1.1. The differance seems to be in the way the new FMC gauge calculates fuel usage. If you replace the FMC gauge with one of the older versions,it'll allow for a longer flight without the"insufficiant fuel" notice,but you'll lose the built in weather radar. Boeing's website shows a maximum range of 5990 nmi. With version 1.2,you won't even get close to that.
