Flight/Ground Ops, Crewing and DispatchA forum for the people who are engaged in operational control/flight dispatch/crewing and their colleagues airside in ramp dispatch, load control and ground handling, to discuss issues directly related to keeping their aircrew and aircraft operational.
I suggest you download the "Getting To Grips with COST INDEX" from Airbus World site. You will have all information how to compute your ideal CI, depending on your airlines specificities.
