Vd and Md on big jets
After viewing some company training material on a nasty jet upset/over speed I was wondering what the actual Vd and Md are on the big Boeings and what sort of tested margin is available.
For example, for a Vmo and MMO of 330/0.87 what would the Md be particularly? CS 25 just says Vc/Mc are limited to a max of 0.8 Vd/Md and a minimum Mach margin of 0.05 or 0.07 which suggests if you get an overspeed beyond 0.92 with the above Vmo you are rapidly becoming a test pilot?
if anyone knows or could point me towards the actual Vd/Md values established during flight test I’d be very grateful.
