I believe Bonanzas can have this problem in certain configurations.

It depends on which where the CG is. If you've got an aft CG
and burning fuel drives it more aft, you've got problems.

In my plane, we typically sit on the forward CG limit with
the tanks full. Since the envelope is sloped on the forward
CG side (the limit moves aft as you go up in gross weight),
even as the CG moves forward with fuel burn, you're also
getting lighter so the CG limit is moving forward faster.

Similar to the Warrior. but you can barely get enough wt in the front to
reach the forward limit. expecially when I am one of them ( 180 lbs). But
it is just possible with a couple of sumu wrestlers and less than full fuel
to exceed the forward limit, in this case burning fuel actually brings you
back in bacause as you say the cg moves forward but the limit moves forward
faster at lower wt.
What is your plane John?
