Cost index flight planning
Boeing FPPM and Airbus FCOM only provide data for LRC and fixed-mach cruising. How is it possible to obtain fuel burn and cruising speeds for specific cost index values based on these LRC and fixed-mach tables?
Same question applies to climb and decent figures.
Thanx!

Since Econ cruise is "adaptive" -- it changes speed/burn with change in wind -- it would require a specific flight planning program that has all those data programmed in.
Even airline Dispatchers can only get a fuel burn for a particular flight by plugging in all the variables, and then doing a "what if" scenario of changing variables.
