Mark,
Wouldn't the force you describe decrease Vne & Va? I don't think it
would impact gross weight?
Does anyone know what the Vne's & Va's are for each configuration?
I'm still curious why the gross couldn't be increased by the additional
weight of the long wings.... I assume they are heavier(?).
Cheers,
Pete

Surely this isn't just down to the weight that the aircraft can carry,
but
must also be related to the load the wings cause on the airframe? I.e.
the
weight increase mode implies to me that there is a leverage effect
turning
on the spar and trying to push the wings into the airframe at the point
where the weight increase mod. bar is placed? So the max. weight the
aircraft can carry isn't just a factor of the load on the wings, but
also
the 'other' effects on the airframe?
Cheers,
Mark.
