May 25, 201115 yr Hi everyone. I recently purchased the iFLY FSX 737NG, to tide me over until "THE" NGX is available. On their member forum, I stumbled upon a very helpful list that appears to show the cost index data for a huge variety of airlines. Now, I know that CI is not really set in stone for airlines, and the the pilots often have the flexibility to adjust a SOP value to allow for a faster/slower cruise as appropriate to how far behind/ahead of schedule their flight is, but it's nice to have a template to help you when simulating airliner ops.This info does not belong to iFLY, the forum poster had obtained it from another public website, just to let you know.I hope this is helpful.Air Baltic 28 B757 CI: 50 Air Berlin 30 Air Canada B767s :100 Air France Short/medium haul flight : 35 La Navette (France) : 250 Longhaul : 45 Delayed shorthaul : 250 Delayed longhaul : 135 Air Malta B737 CI: 25 Air New Zealand B767: 45 Austrian 35 British Airways Airbus Fleet: A319/A320/A321Climb at: Cost Index 0 Cruise at Cost Index 20 Boeing Fleet: Boeing 737-300/400 and 500 SeriesClimb at: Cost Index 0 Cruise at Cost Index 28 Boeing 747-400Climb at: Cost Index 0 Cruise at Cost Index 90 Cost Index 0 (Sometimes used on East Coast USA to UK Flights and less often on UK to Singapore/Bangkok flights) Boeing 757-200 and Boeing 767-300Climb at: Cost Index 0 Cruise at Cost Index 40 Boeing 777-200Climb at: Cost Index 0 Cruise at Cost Index 100 Cost Index 0 (Sometimes used on East Coast USA to UK Flights) British Midland 40 Cathay B744 CI:80 China Airlines 85 (Nur B747) Condor Boeing 767-300ER: 30 Boeing 757: 18 EasyJet Airbus A319 Cost Index: 12 Airbus A320 Cost Index: 12 Airbus A321 Cost Index: 23 EL AL 737's: 15-30 747's: 39(short/mid haul- Europe)757's: 20-40 767's: 30-45(30-40 for Europe, 40-45 long haul) 777's: 71(long haul, ex KLAX) Emirates Airbus A330-200 Cost Index: 25 FlyGlobespan Boeing 737-700 Cost Index: 14 Boeing 737-800 Cost Index: 13 FlyNiki 35 Hamburg International Airbus A319: 40 Boeing 737-700: 30 KLM F70/100 Climb/Cruise : 30/15 737 Climb/Cruise : 30/15 A330 Climb/Cruise/Descend : 60/150(300)/30 MD11 Climb/Cruise/Descend : 50/100/20 777 Climb/Cruise/Descend : 50/100/20 747 Climb/Cruise/Descend : 150/300/50 Lufthansa Airbusse: 30 Boeing 747-400: 70 Airbus A300-600: 35 Boeing 737-300: 25 Lufthansa Cargo 80 Luxair 50 Nordavia Boeing 737-500 CI-27 NordStar Airlines (??????)

May 25, 201115 yr Interesting list. Thank you.Didn't know that they even alter the CI for the different phases of flight.
May 25, 201115 yr Author I think airlines sometimes use a higher number cost index during the takeoff phase to better comply with ATC demands in the busy terminal space (i.e., expedited climbs, or speed changes for proper spacing from other traffic). When I say a higher number, I mean better performance at the expense of fuel savings. Once they are in the cruise phase, there may not be such pressure, so it would feasible to allow the aircraft to follow the most economical profile, thus a a lower cost index which lowers speed to save fuel.For the most part, when planning my fuel load I will use the SOP airline cost index. But until I'm above 10,000ft AGL, I will use 100 (or whatever is listed on the above chart) CI. This is one of those obscure tidbits I happened to pickup on the net from real world pilot reports, I'm not sure if it's common practice. A.J. Domingo
May 25, 201115 yr Im pretty sure that most airlines wouldnt use a higher cost index for departure, instead they would have just used speed select if the departure speed was too slow. Its true that most airlines use two different cost indexes for cruise tho, one for normal, on-time operations, usually a very low number, and another one for situations where they are behind schedule, often a much higher number.

May 25, 201115 yr In case anyone was curious, what Cost Index actually does is: At the maximum CI value (typically 200 on old FMCs, 500 on newer ones), it puts the aircraft up near Vmo for climb and cruise and up to 330 knots for a descent (not overriding speed restrictions), At the minimum CI value (zero), it puts the aircraft into airspeeds that will get you maximum range and minimum fuel usage, although you'd certainly need decent wind data input into the FMC to have that work well.I mostly just use a value of 100, I don't have to pay for my virtual fuel - except virtually in Air Hauler - but even then it doesn't really matter much since CI is an index of the fuel cost versus time-operated cost, and the maintenance in Air Hauler is not done to a level of detail which makes that especially relevant, as it always goes simply off hours on the airframe or damage incurred. It can be fun to see if you can save a bit of fuel and I generally do try to cut down on flight times by screwing around with things en route, including altering the cruise altitude and occasionally steering around weather, but I don't exactly beat myself up over it, although if anyone was simulating a real world's airline operations, I agree that it would add a touch of realism to use the CI which the real airline generally uses.Al Alan Bradbury Check out my youtube flight sim videos: Here
August 23, 201114 yr The Cost Index = fuel consumption in KG per minute? Like a cost index of 70 would be 70kg of fuel per minute?
August 23, 201114 yr IIRC, CI = Fuel related costs (price of fuel) / Time related costs (Time of Flight) Also, I'm reasonably certain that this list is severely out of date. Most of these CIs predate the massive hike in fuel prices that occurred ~2008, since they all seem rather high. Southwest started using 20 for all aircraft back in 2008 (?), UAL switched 0 on the 757s at about the same time, and COA was using 7 on it's 737s. Joe Sherrill

April 17, 201313 yr Yeah, KLM numbers are not correct either, I believe that they use 6 (737), 7 (738) and 9 (739). I don't think anybody uses 30 on Boeing 737s these days. vatsim s3
