I was wrong,

my equation don't give a good result, worst when I submit the same data to another software which give %mac the result is not like in the loadsheet, I am lost!!!

If you have an idea

Here some equations :

Code:

     
            ( Harm - H25% ) * W Index = ----------------------- + K
                         C
                100*C*(Index - K)                 100* ( Harm - H25% )
% Mac = ------------------------------- + --------------------------
         Weigth * Length of Chord            Length of Chord

best regards
