Excellent excerpt - it was what I was trying to say. Thanks.

Would anyone care to comment on the accuracy of this illustration of how
wing dihedral works from a 1981 Jeppesen Sanderson book.

The accompanying statement reads:
"When an aircraft with dihedral rolls so that one wind is lower than the
other, the lower wing will have more effective lift than the raised wing
because it is not tilted from the horizontal as much. The imbalance in lift
tends to raise the lower wing and restore level flight."

This is not quite correct, and most of the "pilot books" have it wrong
too. Here is a very nice explanation taken from the book titled
"Mechanics of Flight" by A.C. Kermode of the RAF. (snip)
