that other post mentioned ‘defined minimum manoeuvring speed’ which is a totally different concept
Indeed, Dave. However, when I ran a search for DMMS (a term which I had never encountered before) the hit provided both Va and Vs related considerations. I get the impression that DMMS is a term coined by the lightie fraternity in the US ? The DMMS, being a simple load factor increment to Vs still is a bit silly without any margins being applied. I note that a similar idea is used on heavies for manoeuvring margins, but with a sensible stall pad.
