VD/MD

[Shandy52]

I'm reasonably familiar with most terminology covering airspeed and Mach number (e.g. Vmo/Mmo) but hadn't come across VD/MD prior to following the R&N Air Asia Indonesia thread. Could someone explain the meaning of the "D" here, please? Disaster? Destruction?

But of course :-). Seriously though...

Then I hope he will accept my apology, and thanks. Thanks to you also.
