25 kwi 2016 · The cost index is a number used in the Flight Management System (FMS) to optimize the aircraft's speed. It gives the ratio between the unit cost of time and the unit cost of fuel. With this number, and knowledge about the aircraft's performance, it is possible to calculate the optimal speed for the aircraft, which results in the lowest total cost.

2 maj 2019 · The Cost Index is meant to balance between the two: Time cost. It accounts for all time dependent costs, such as: Hourly maintenance cost. Engines, Auxiliary Power Units. Crew cost, though it can be fixed or independent of the flying time, in some cases. Marginal depreciation or leasing costs.
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. 𝐶𝐼 = Crew cost per time.
5 lis 2020 · Cost Index – Basic Principles and Rules. The video explains what Cost Index really is, what it is not, and also offers some guidance on its use in the cockpit.
4 gru 2023 · Definition and basic explanation. Cost index is a value assigned to an aircraft that determines the balance between fuel consumption and time. It is calculated based on various factors such as fuel prices, aircraft performance, air traffic management, and operational costs.
1 sty 2018 · In this paper, we provide arrival time prediction combined with a cost index optimization model for short haul flights. Our work is based on flight data of a European network carrier. We focus on predicting the arrival time for incoming flights at two hub locations.
