'Scuse, Peter, but I said "all the V speeds you're talking about",
not "all V-speeds".

As best I can tell, the original poster was talking about
Vr, and landing speed.

Whatever. I find Vx and Vy to be perfectly relevant in this thread, even
looking at only the first post. You want to be offended, go right
ahead...wouldn't be the first time.

Vx and Vy are certainly relevant to bring into the discussion, but
they weren't mentioned in the original poster's description, and I
referred to that. You were responding to my post, and saying "not true"
to me. I simply clarified what I'd meant.

That doesn't mean that Vx and Vy aren't relevant to introduce, as
additional factors which *are* dependent on factors other than stall
speed. It's a reasonable point -- provided it's not introduced in a
way which puts words into someone else's mouth or refutes a claim
they weren't making.

I await your explanation of Vr and what it depends upon, and I note
that one can fly behind an engine later shown to have one cylinder
completely flat, and not notice any particular changes to Vy, the
rate of climb obtained at that speed (under DA conditions not near
the edge of the envelope, admittedly), or cruise airspeed.

Cheers,
Sydney
