No, best glide doesn't do that. The best loiter speed is a bit lower than
that
for the best angle of climb. It's usually not published, but you can
determine
it pretty well by empirical experimentation.
Vms really has nothing to do with Vx. Vms minimizes power-off power loss,
Vx maximizes power-on excess thrust.
Vms is easy to calculate. It's just 76% of Vbg (make sure you do
IAS-CAS-*0.76-IAS; i.e. multiple CAS, not IAS).
