Flex value

[regard]

Hello,

Please could you let me know why the Flex value returned by EFBV2 is not identical to the value returned by the PMDG 777 LR running on P3Dv43.

PMDG value is always bigger of about 4 to 5 %

Which one is closed to the reality ?

Thanks for your help

I guess you are talking about TOPCAT, right? EFB v2 does in no way calculate any performance values. Therefore if there is a discrepancy between TOPCAT calculations through EFB v2 and Calculation directly in TOPCAT (that's what I assume you are talking about), it is my strong assumption that those two calculations are not based of the same meteorological data. Otherwise TOPCAT would deliver identical results.

I mean the difference between Topcat/EFBbV2 value and PMDG777 flex value returned by the FMS .

Topcat/EFBv2 and PMDG get meteo from Activesky.

Ok, once again: EFB v2 does not do any performance calculations! If there is a difference between TOPCAT and PMDG calculations, then this is definitely the wrong forum!
