5.481 seems correct. Why do you think it should be 0.086?
Thank you for the prompt reply.
If 5.418 is the CLa slope then I misunderstood something.
I calculated by taking the slope of the green line, also labeled CLa.
I have approximately taken:
m = y2 - y1/ x2-x1 = 1.40 - 0 /10 - (-5) = 1.40/15 = 0.093
Please ignore 0.086. but still its far from 5.418?
How was 5.418 calculated?
unless angles are expressed in radians?
so 1.4/Radians(15) = 5.34???
Yes, CLa is expressed in radian
Thanks so much for confirming
