While this is my philosophy as well, I do have to wonder: if an aircraft
is
designed for a particualr gross weight, does consistently flying it over
gross put stress on the airframe that will, in the long term, weaken the
structure?
From the reading that I have done, the air loads for an over gross airplane
are less than a plane that is light. This is from the idea that calculated
maneuvering speeds (speeds allowed in turbulence) are allowed to be higher
with a heavy airplane.

From a simplified point of view, the highly loaded wing will slip (mushing
instead of grabbing a good bite of the air) when loaded, producing less G
than a light airplane with the wing grabbing the air easily, and changing
directions quickly, producing more G's.

Taking off on a rough field while heavy or landing heavy could still hurt
the airplane, I guess, though.

What do you all think? Is this a valid line of thought?
