People were beginning to talk about all the different
maneuver that can be done in an airplane [in this case the
172, but this applies to all airplanes]. The OP asked about
"normal category" but even allowing for utility category,
the 172 is approved for very limited aerobatics. The
specific allowed maneuvers are listed.

Certainly, any airplane can perform any aerobatic maneuver,
since all the controls are present for all axis.

But just as any camera can take portraits or porn, any
airplane will only do what the pilot can do. If your name
is Bob Hoover et al, you don't need to ask the question and
you probably can do these maneuvers. But Joe Sixpack is
going to do several things...(a) bend the airplane (b) break
the airplane (c) wish he had a quick jettison door (d) wish
he had a parachute and (e) die.


Simple rule, The Law of Gravity has no exceptions or
appeals.

I will be flying a 172 in the morning, I will roll it and report the
results.
