Real World SOP values for Cost Index/Takeoff flaps

Featured Replies

Hi captains, I have been flying the MD11 exclusively for the past 2 months, attempting to fly according to real world SOP as closely as possible. These are three important airline specific settings that can be found through research, but I was hoping that a thread like this can list all present and former operators SOP values in one place to help us operate in accordance to RL procedures.I have listed below what I have found, and I would be grateful if others with more knowledge or access to these SOPs can add to this list/fill in the blanks/correct value. I'm hoping for general figures, I'm sure some airlines allow the specific route or runway conditions to dictate what values to use, but a list of commonly accepted figures for normal ops would do just fine. If any t/o flap setting can be used for optimum performance, it should be listed as "dial a flap".Swissair - CI:80/TOFLAPS:22/Descent:290 PolicyFedex - CI:200/TOFLAPS:25/Descent:290 PolicyLufthansaCargo - TOFLAPS:20KLM - TOFLAPS:DialaFlap or 28Alitalia - TOFLAPS:25CargoItalia - TOFLAPS:DialaFlapMartinair - TOFLAPS:25

Hmm, I thought FDX uses CI 80 and flaps 22 (that's what I have in my VA SOP).

I have the Fedex FCOM from 2009, they use flap 25 and deflected Ailerons are deactivated across the whole fleet. I wouldn't worry to much about the cost index, this can change a lot, however the FCOM says enter 200 if not provided with a cost index otherwise it's 80Regards

Good idea A.J. Some sources in the internet (unfortuantely wikipedia) quote the Cost Index for Lufthansa Cargo to be 80. Maybe someone has more current information on that.

I'm sure there is plenty of conflicting info out there on the interwebs (also old info, as in cost indexes used before the runup in the price of oil/the financial crisis of 2008). The idea here is to assemble current info from those lucky enough to have access to this info for our benefit. I noticed on my Fedex fight in cruise that changing from 200 CI to 40 CI added just 8 minutes to the ETA, not a huge difference as I would have expected. The CI can be a mystery, but I am very interested in the Takeoff flaps/descent speeds used by individual operators.It would be great to see an online database for such intricate details for not just the MD11, but other heavies. I love how PMDG allows you to customize the cockpit presentation according to Airline for their jets, it would be great to have such a online resource with tables, especially for the upcoming 737NGX.

Am I wrong in thinking that take-off flaps varies with FLEX-settings? (altitude, temperature, pressure, rwy length...)

I don't think the flap settings have to do with Flex, but the Flex has to do with the Flap setting. Of course I might be wrong, but that's how I had it in my mellon.Great idea AJ, I like the idea of consolidating the info too.

For instance, in the MD11 there are multiple display options for the PFD, like how to depict the winds as an arrow or cross, flight director as a cross hair or single cue, dial or tape engine data display, etc. It's nice to have those options, but I have no idea which options are actually used by the MD11 operators. I'm doing a lot of Fedex/UPS md11 cargo flights, and wanted to know which setup they use. I suppose I could research the web and look for photos from the cockpit, but the idea here is that maybe PMDG or others could list what those options are by airline. This will be very important for the 737, as you know there are so many variations between the way airlines display such data (i.e Southwest which has their glass PFDs display the old fashioned "basic T" layout of the primary flight instruments in glass format to standardize operations between the glass NG and older "guppy" models). I just learned about that by accident when seeing cockpit photos on airliners.net, I think Southwest even went so far as to not install autothrottles to save weight.Basically, I envision a webpage or document which goes into such nitpicky details would be a great resource for users on a quest for ultimate realism and fidelity, and one that takes info scattered all over the web into one place for easy reference.

That table/website would be very helpfull. Otherwise it would just be a guess as to what options you fly with, especially with the ng. I know that KLM fly with the tape engine data on the MD-11, but don't know if there are any others.

Lufthansa Cargo:-

 

Cost index 30

 

M.82 when fixed Mach required EG. North Atlantic

 

Deflected Airlerons and flaps 28 available

 

All takeoffs optimized via the workpad (so all flap settings maybe used)
