I've seen a post about this on the forum before, but I was unable to fix my problem from it. Today I loaded up a flight completed the PERF,POS,etc pages. and activated the flight plan..as soon as I did that there was not an accurate fuel reading in the PROG page so I had now idea whether I would run out of fuel...Also there is not top of descent calculated either. this is the route if it helps..
