2. And the most effective way to take all these factors into account is to use the Cost Index (CI). 21 This has a direct impact on the CO2 emissions from the aircraft, with higher speeds resulting in higher 22 fuel consumption. Used appropriately, the cost index (CI) feature of the flight management computer (FMC) can help airlines significantly reduce operating costs. Used appropriately, the CI feature of the flight management computer (FMC) can help airlines significantly reduce operating costs. VARIAbLE FUEL PRICES, FUEL TANKERING, ANd FUEL HEdGING MAKE THE COST INdEX CALCULATION COMPLICATEd. Employment Cost Index for wages and salaries, for private industry workers, by occupational group and industry [Not seasonally adjusted] Occupational group and industry Index value (Dec. 2005=100) Percent changes for; Sep. 2019 Jun. The index and price data shows the global average price paid at … The Federal Aviation Administration issued an order Wednesday that paved the way for the troubled Boeing 737 Max to carry passengers again, ending the jet's 20-month grounding. Graph and download economic data for Employment Cost Index: Wages and salaries for Private industry workers in Aircraft manufacturing (CIU2023211000000I) from Q1 2001 to Q3 2020 about aircraft, ECI, salaries, private industries, workers, wages, private, manufacturing, industry, and USA. 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. If you would like to help test or recommend changes to an aircraft profile, please contact me! Cost Index You’ve probably heard the term being thrown around the forum or when reading or watching aviation related articles or videos. As an example, time-related costs contain the sum of several components: CI is used to take into account the relationship between fuel-related costs and time-related costs. This is the single and only purpose of CI, keeping in mind that wrong utilization or wrong calculation of it leads inevitably to cost penalties. CI effectively provides a flexible tool to control fuel burn and trip time between these two extremes. By balancing time-dependent costs 20 with the cost of fuel, it controls the speed of the aircraft to achieve the most economic flight time. Version 1.3 Download 16642 File Size 1,5 MB Create Date November 3, 2017 Download Download our latest Cost-Index Database for many different … Read More[DOWNLOAD] Cost-Index Database | TOGA Projects So, using the maximum CI is logically justified. This documentation is copyrighted as part of the intellectual property of the International Virtual Aviation Organisation. A4A produces the U.S. But what is cost index, and how is it used in real world aviation. In essence, the cost index is used to take into account the relationship between fuel-and time-related costs. With time-related costs, the faster the aircraft is flown, the more money is saved in time costs. Airbus Flight Operations Support & Line Assistance - Getting to grips with the cost index (issue II - May 1998), Michael A. Burris - Cost Index Estimation by Boeing (August 2015), CAE Oxford ATPL book - Flight Performance and Planning. As the CI will vary from operator to operator and may also vary between flights of the same operator, the air traffic controller cannot assume that all aircraft of the same type will perform in the same fashion during any given phase of flight. Used to estimate costs. The formula may look simple enough but … It quantifies choices concerning flying faster to recover delay, or flying slower to conserve fuel. Regarding IVAO, it's clear that the CI concept is something left out of consideration. In addition to the above time-related costs, extra cost may arise from overtime, passenger dissatisfaction, hubbing or missed connections. 1.

This jet fuel price index provides the latest price data from the leading energy information provider Platts. For example, one airline generally uses a CI of around 9 in the A320 which results in a climb speed of about 290, a cruise speed of about .76 and a descent speed of about 260. It could be scaled from 0 to 999 or it is going from 0 to 99. However, if the aircraft is running late, the crew may use a CI of 50 or more which would give speeds of 320, .79 and 330 for the same phases. … [Search] CI is used to take into account the relationship between fuel-related costs and time-related costs. It will help to make flight planning more precise and accurate. More sophisticated flight planning programs will show this change on a leg by leg basis and will file the speed change as part of the ATC flight plan. It is the MINIMUM TIME MODE for Maximum Speed (VMO/MMO).
