Sensible, this has nothing at all to do with normal and utility aircraft!!
If you look at the C of G diagram for Mr Pipers Warrior you will see that there is a utility category with more stringent weight and C of G positions in the same diagram as the normal category. Looking at a diagram for a 180 the utilty section of the graph shows a max wt of just under 2000 lbs with a C of G falling between 84 and 86.5 inches aft of the datum. The normal cat is much less restrictive with a max all up wt of 2400 lbs and the C of G falling between 84 and 95.8 inches aft of the datum, to cover myself this is for one of the aircraft I instruct in and not for planning purposes!!
To the best of my knowledge the aircraft must be loaded in accordance with the utility category part of the diagram if the intention is to carry out stalls in the aircraft. Failure to heed this takes you in to test pilot territory
and more than likely will invalidate your insurance.
As always if in doubt read the POH
