What is "cost index" when used for aircraft flight planning purposes? - index of fatgirl.jpg
For our pilot line: What is the index of "costs" when used for flight planning? Can you give an example?

The cost of the escalation of the practice of assessing the impact of the cost in the hope of minimizing the sum of these factors.
Many aircraft are equipped with several computers with high performance to the best speed of travel (that) will determine the rate of the economy in order to minimize the total cost of operating the flight. To this end, the FMC, the need for information regarding the costs in time and fuel cost. Fuel costs are legally on price and quantity of fuel required for the flight (with caveats, based etc..) Instead of all these factors in each onoard FMC, most airlines use a ratio of these two costs, the speed of economic to determine for a particular flight on a particular day. This relationship is defined as the cost index, and determines the speed of the economy for a flight to minimize the total cost of ownership.
Cost Index = cost of time / fuel costs
Cost Index (CI) is the relationship or connection between time and fuel costs. It is based on a balance. In a Mach number of high fuel costs will be higher, but will be offset by the fact that the time factor is lower, and vice versa.
Flight Management Systems will be able to get with the Mach number and amount of the cost of time with fuel costs, balance, and thus creating a IC.
Each of these Airbus aircraft, and each business has unique values for this index.
I seconds the previous answer. I would not have said it better, and I'm an engineer for the development of FMS.
