The file is not available can someone give a download link.

 

 

Thanks

Hi

 

I just get taken to file dropper no file to download just an option to either sign in or upload my own file

Yep it shows the homepage of filedropper.com, not download link at all . Please recheck, I appreciate that .

Yep, the download link is down...  :huh:

 

btw. what are you experiences with this Excel fuel calculator? Any issues or miscalculations guys? 

Hello Guys,

 

Sorry for the late reply. You can download from My Website.

Thanks Robbie.

Thank you

Hi Robbie

 

could you please explain how to find the correct trip fuel minutes in order to use this fuel planner. I understand how the calculator works but obviously in order to get an accurate result you have to have an accurate figure of mins to enter as trip time so how do you get that figure taking in to account winds aloft at each waypoint

 

 

 

thanks

Hi ! Nice Work, but the winf at cruise doesnt affect  the fuel used? Need to adjust the quantity given in case of headwind ?

Hello,

 

The trip time takes into account head/tail winds.   I don't have a calculation for trip, but regardless of what your ground speed is the 777 burns fuel per minute not per ground speed.   There's no way I or anbody can re-created something accurate enough to plot the average head/tail wind to get a correct trip time unless you have access to all the weather data stations globally.

 

Use a planner that does this for you, then input the trip time into this planner. The rest is done pretty automatically for you.   Additional, APU, Taxi and Alternate are the other variables you can change. See notes in Spreadsheet for descriptions. But most Airlines use 12-15 minutes for APU, 6 before start, 6 after landing and parking up.   Taxi at most places is 15 minutes, big airports such as Heathrow it's 20.

 

Examples. (Doesn't Include other variables)

 

EGLL-KJFK BAW179 - 7 hours 11 minutes planned trip time.  (431 minutes) =48,018kg for 431 minutes

KJFK-EGLL BAW11J - 6 hours 01 minute planned trip time. (361 minutes) =40,219kg for 361 minutes

-hi Robbie

 

I have created an excel that does indeed take in to account wind component using activesky data for winds aloft at each leg at what ever altitude you chose giving extremely accurate adjusted trip time but I was wondering how you have accounted for the difference in fuel burn as the flight progresses as the burn rate alters dramatically during differed phases of flight. obviously you can use an average figure of burn per hour and I can see that you calculator uses the overall trip figure which would include climb and decent stages of the flight therefore you must be using and average figure right? and then depending on initial take off weight the burn rate  will be significantly different  from a heavy take off to a light take off etc etc. there are so many vairables  that affect burn rate I find it hard to be able to use an average blanket burn figure and still get accurate results for any tow flight.

Hello Kav,

 

I used a real world burn figure from Emirates Flight Planner (Real World) for the trip fuel. I don't think it can get any more accurate than that.  It won't be the same as the real world flight but surely there'd probably be only a few kg's out of sync.
