mmm interesting note on the CI modelling. That could indeed be the root cause of minor variances. The big diff I think boils down to the LEAP fuel efficiency not being accounted for properly… it can’t be sheer chance the difference is 20- 30% or the same as the actual fuel efficiency improvements
Another Flight just then, Melbourne to Brisbane… a little less precise to the FP. If I were to add a Fuel Factor of P23% in Simbrief my flight was within 300lbs of estimates, and that would eb the long slow final approach.
Therfore… all future flight plans I will use P23 fuel factor, until the next change.
Winds, yes… the winds aloft ARE accurate in FS with live weather. The predicted 60kn tail wind was present in the simulated flight. Since I started manual fuel planning originally, I have noted the real v simulated winds are quite accurate. Another example, with pics below from today’s flight. They were 100% accurate until the end of the flight where I started getting heavy gusts up to 110kn (see screencap below). - previously btw, I flew through a cyclone, remember that one that hit Greece in the Med last year? Welp it was in the sim too. Technical issues aside… this sim blows my mind sometimes, and how connected our world is.
One thing I have noted… Australia is hella windy at altitude. The tropo line btw shoots off the chart on the cusp of a cold front
and the cyclone, cause why not… with real weather satellite at the time. (DA62)
