jtr....
to add to your confusion, all of the above are correct.... your queirie re CI0... well as you know if it flys, floats or F**** then you have to pay for it. CI 0 does not in practise give you best fuel econ due body angle just as 999 does not increase A/C performance. CI is only effective if each A/C has a flight plan which is relevent to each particular one (history fuel burns) and the perf factor on A/C status page is updated to the corrected index. Now we must add in our variables (fixed variable and so on..). I have flown for different operators who use different CI's. Bottom line.... very few companys use same correctly as it is too much effort correcting the CI for all flights due to route costs, winds aloft, temps aloft, schedule and so on....
Happy hunting............
