Creative Speculation

Seger,

The FAA did not say anything different to what has been explained to you by me and by FAR Part 25.

As the FAA correctly points out, "Ultimate load = Limit load x a factor of safety (1.5) thus Ult. = Limit x 1.5 "

Notice he doesn't say Ultimate "case" = Limit "case" x a factor of safety (1.5) thus .....

Nor does he say Ultimate 'speed' = limit 'speed' x factor of safety (1.5) thus...

As you have finally understood after I have repeatedly tried to explain it to you (and realizing not even Beachy is supporting your BS interpretations of FAR Part 25), Vd is not a limit load it is a speed.

Why don't you email your FAA source and ask him straight up... "is there a 1.5 margin of safety above Vd as described in FAR 25.303?"

He will tell you the same thing i have been trying to tell you. FAR 25.303 is for loads, not speed. The margin of safety for speed is between Vmo (derived from Vc) and Vd. The ultimate load (1.5 x limit load), is required up to the maximum speed (Vd).

In short, you have not proven anything but the fact you still do not understand FAR Part 25 and the three types of loads defined under 301, and regulated by 303 and 305.
