CI - Cost Index

[Wayne Pierce]

Greetings Pilots, This information is taken from https://www.togaprojects.com/ .

What is the cost index or CI?

During a flight the cost mainly comes from two different things: the hourly crew cost and the fuel cost,
both depends on time. The cost index synthesizes both costs in order to minimize the cost of a specific
flight by giving priority to the fuel consumption or the flight time. This allows to calculate speeds and
optimum altitudes. In a nutshell the higher the CI is, the costlier the flight is.

Usual cost index values are located between 0 and 200 depending on the airline, type of flight, and
delay, it can be changed during flight for schedule purposes.

Accuracy of this database

This database is aimed for flight simulation only and for realism purpose, it is based on real world data.
As this document mainly depends on user’s feedbacks and many other sources, some values may be
slightly outdated or wrong. Some airlines or aircraft in this document may not exist anymore or may be
retired, they are left here as simulation still allows to fly old airlines and retired aircraft.
The real world cost indexes also regularly change depending on the oil barrel price and this document
is based on typical values.

Thanks,
WLP

Thanks for the information Wayne. I was surprised to see "crew cost" included in the calculation. I always thought it was strictly based on fuel cost and time.
