I think I understand the reasoning behind Va, the max maneuvering
speed, being that the wing will stall (and thus dispose of the
loading) before it breaks. This is why Va falls as the weight falls,
because at any given IAS a higher weight takes the aircraft closer to
stall already.

There was a long thread in January, "Va and turbulent air
penetration speed" which you ought to be able to find
on Google.

Can I suggest that avoiding turbulent air is simply the most pragmatic
approach?

It's broken enough airliners for starters !
