a specific Va is valid only at a specific weight, with

Show me a Part 23 requirement that says so.

Part 23 isn't what makes an airplane fly. Aerodynamics are. And those
aerodynamics clearly show that at a given weight, a slower airspeed is
required in order to limit acceleration to a given number.

Oddly enough, many aircraft manuals bear this out, providing lower Va speeds
for lower weights.

Todd Pattist has lectured on this a couple of times, and he's right.

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