Overweight takeoff / flight

Then you haven't read Part 23.

Yes, I have.

Let me point out the sections to you:

Those sections stipulate, given an existing Va, how the control surfaces
must be designed. They do not in any way define Va.

The point is that at Part 23 doesn't require this. And not all
aircraft publish such variations.

You are still hung up thinking that Part 23 is what makes airplanes fly.

Again, you didn't read what I wrote. I said it doesn't scale UP.
Flying over max gross may increase maneuvering speed, but it doesn't
increase VA, because the increased weight won't protect control
surfaces from failure.

In this context "maneuvering speed" is synonymous with "Va". Yes, you're
right, there is only ONE Va. But in the world of piloting, we commonly
understand the shorthand "Va" to mean "maneuvering speed at a given aircraft
weight" where the weight is changeable.

Tangent? It's the essence of what Va is.

Not in this context it's not.

I seriously doubt Todd has told you that Va remains the same
regardless of aircraft weight. You obviously misunderstood him.

Ok, you read what he wrote and tell me:

If you think that he was explaining the aerodynamics of maneuvering speed,
you misunderstood him. If you don't think that he was explaining the
aerodynamics of maneuvering speed, then your comments based on that quote
are irrelevant to this thread.

we commonly understand the shorthand "Va" to mean "maneuvering speed
at a given aircraft weight" where the weight is changeable.

Then what is commonly understood is not correct, because that's not
how Va is *necessarily* determined.

Not in this context it's not.

PARTICULARLY in this context. The control surfaces were designed with
withstand full movements at PUBLISHED Va, not his new, derived, HIGHER
Va.

There are any number of structural issues raised by overgross flight. It
was clear to me which one he was asking about, and the control surfaces
ain't it.
