Ha i was been for a while not fly FSX,seem jonathan was keep working for fans of MD-11.

 

Thank you Jonathan!

Hello,

 

Today I have got the version 1.1.0 of this fuel planner for you. Beside some bugfixes it contains a very small new feature. You can now enter the ICAO identifier for an airport first, and it will automatically load the name of that airport, as it is saved in your Navigraph/Aerosoft Navdata.

 

This is function isn't really necessary, however I made it as a small test. I plan to add a function to import flightplans/enter waypoints, so that distances can be calulated automatically and winds can be entered for certain legs. However, to implement that it will take some time, so don't have any hopes.

 

You can download V 1.1.0 from here. As always, feedback is very appriciated.

 

Best regards,

 

Jonathan

I just found this thread, Jonathan, and I have just downloaded v1.1.0 and anxious to try it out.  You are indeed, the guru of the MD11!  Thanks.

Hi Jonathan!

    Just finished installing and using v1.1.0 and everthing seems to work perfectly.  I tried different scenarios and no crashes or problems.  I am curious, however, in that the final fuel figures that you list don't total up to the load figure you recommend.  Seems no matter what combination I use (my example is just a short 2000nm test flight @ FL330) it seems to add 4000# to the total fuel figure.  Is that some MD11 minimum fuel requirement or something?  I tried to see if I could find something in the FCOM about that but could not.

 

    I am going to use your final figures for a short hop from VMKK to YPDN this morning.  I notice you have included the wind component and adjusted for it but what about the temp aloft?  That certainly does affect engine performance and also fuel burn, doesn't it?  In this case I am flying in the tropics and will have above ISA temps at the altitude I will be flying so anticpate a higher than normal fuel burn.  Will report my results.

Hi Craig,

 

Thanks for your feedback!

Very good spot, I guess you are the first one to notice that! Yeah, you are right, the suggested block fuel can be arround 2.000 kgs / 4.400 lbs greater than the sum of all previous fuel entries.

However, only if the landing fuel is less than 11.000 kgs / 24.000 lbs.

This can be because of one of the two following reasons:

- The distance to alternate you entered is smaller than about 50 NM  and/or

- your contengency fuel is low due to a low contengency percentage or short route distance.

 

I had to do this because if the FMC estimated landing fuel level is lower than 11.000kgs / 24.000 lbs a insufficent fuel message is triggered.

Yes, very true, temperatures affect the MD-11's fuel consumption. However, the problem is, until today I have never found a document which would allow me to find such specific informations/factors about the MD-11's fuel consumption. After intensive search, I was able to get my hands on 5 .jpg pictures. Those where scans of tables from a passenger MD-11 operator, which showed the fuel consumption depending on weight, wind komponent and altitude up to 2000 NM.

I did my best to use the data I had to create a fuel planner which was as precise as possible. However, due to missing factors, this software isn't that precise as it should be. Temperature beeing one of them.

The lack of usefull data left some shortcomings in this software. One of them beeing the calculation of alternate fuel.

 

I can't do much about it, until I find better tables, charts, etc. about the MD-11 and/or MD-11F.

 

Best regards,

Hey Jonathan, no complaints here!   I think what you have done is great and I understand about the extra 2000 KG fuel.  As you know I am new to the MD11 and didn't know about the work you had done in creating this much needed tool.  I did puzzle over how to compute fuel load when I first tried the simulation since I could find nothing easily accessible about it.  I did not search the Boeing site.  I tried a couple of flights at altitude with average fuel loads in ISA conditions and noted the fuel burn / hour and began just using a rough estimate of 35#/nm for eastward and #37/nm for westward flights.  Pretty crude method to say the least but it was all I had until I discovered this thread.  Also I am not one to fly along at economy settings unless it is going to be a maximum range flight.  I bump it up to around M.83 to M.835 when I can.  I also keep my climb speed to 320/M.81 so I can climb faster to the more economical altitudes.  So I know there will be a difference in my fuel usage compared to your program which  I assume would be based on most economical parameters.  Fuel is cheap in the simulator so I push it a bit more than RW! lol.  Again thanks for the great work and your help on my other questions.  

Hi Jonathan,

 

Again, I love the fuel planner and appreciate the time you put into it.  I wonder if being able to adjust taxi fuel would be taken under consideration.  It's something I do in other fuel planners and just want to provide a suggestion.

 

Thanks so much, it's my go to fuel planner.

Hi Chris,

 

Thank's for your kind words and for using my fuel planner. 

 

I totally forgot about the option to adjust taxi fuel...  :blush:  The online version had it, so I don't know why I forgot it in the software version.

 

I will definitely implement this in the next update.

 

Best regards,

 

Jonathan

Thank you Jonathan for this great utility! I use the last version and i can say it's very precise

Thank you Zeljko for your feedback! Very appreciated. 

 

Schönes Wochenende noch!

Hello,

 

Today I have got the version 1.2.0 of this fuel planner for you. Beside some bugfixes it contains the option to choose your taxifuel as Chris suggested.

 

For further details see the included changelog.

 

You can get it from here.

 

Best regards,

 

Jonathan

Thanks Jonathan!

 

Schönes wochenende ihnen auch!  ^_^

Thanks John for a long awaited MD11 fuel planner (v 1.2.0). Just something that I observed today using it for the first time. When I select Lbs as weight, both in MD11 Load Manager and in Fuel Planner, with FSX running I then go to my FSX.exe and double click as stated, the fuel planner then closes. On rerunning it, selecting Lbs and MD11 then Get Payload there are no pax details, the cargo weight shows as 142894 (MD11 LM is 56163). If I do not select the Lbs and MD11 boxes and only select FSX as sim I then get the correct figures as shown in the MD11 LM. Not a serious problem, maybe I am doing something wrong but can get round it. Once again, many thanks.

Hi Kevin,

 

Thank you for your feedback.

 

Sorry, I don't get it. Can you post some screenshots? Or maybe post it in German if thats easier for you.

 

Best regards,

 

Jonathan

Thank you so much for all your effort!
