When I run it, I get an error, saying that a file is missing. Thanks for your effort, and I look forward to seeing a working version.Andrew

Absolutely fantastic work!Did you all make sure to put the data files (*.dat) in the same folder as the .xls file? The Excel file needs to reference them in order to operate correctly.

i had to upgrade my previous comment when i found out the assumed temp area..its now a FANTASTIC program! excellent job!:D

congratulations!! this is really amazing and a great tool!my only remark i have so far is that the program doesn't work correctly when the decimalsign in windows is set to , instead of . It might be different on the 747 but it is my understanding that assumed temps below ISA+15 have no effect at all and therefore should not be used .. on the perfomance date i have for the 737-400 you can calculate max assumed and minimum assumed temps, i suppose this exists for the 747 as well??anyhow, it's a great utility that from now on will be mandatory for my preflight of the 747!great job!Jan

I played around with the decimal problem and it (hopefully) should be solved in 0.93b now.For the derated tempertures: The minimum derate temperature is +16

Hi Christian,Well done! Thanks a lotMichael

Thank you very much spending so much effort doing this great program! It's just like in the real thing and I'm looking forward to test it. Keep on the good work.
