I tried doing a 4900nm flight from YMML to PHNL in the Qantas 767 using a CI of 20 and received the "insufficient fuel" warning. I lowered the CI to 0 and was still getting the warning. I chose not to do the flight because I didn't want to run out of fuel after a 10 - 11 hour flight seeing as the FMC was showing that this would occur between CHEEM and CARRP just as I would be getting ready to start the OPACA4.CARRP STAR. That made the range to be about 4700nm. :(

I never tried a really long distant flight like that with v1.0 or v1.1.
