It's a certification limitation, Jose.

Ok, then your airplane may well have the control authority to do it, you
just (wisely) don't want to find out the hard way. However, when you
asked:

The question I asked at the start wasn't if the flight path exists --
it does -- but rather, is there an airplane that has the control
authority to fly it.

it implies that you didn't believe spam cans could. Now I understand
the real question is whether the sim of such spam cans can, by which you
may infer that the real one can (or that the sim is inaccurate - I don't
know how you'd pick between them)
