normal/utility category

"AINut"
A Mustang II is rated at 1600 lbs in the utility category, but no spec is
given for the normal category. Normal cat will allow a higher weight
capability, AIUI. Is the difference between the two based solely on how
hard you G-load the plane during flight? What about landing weights or if
you prang it pretty hard? (Of course, none of US ever do that!) 8-).


A few things. There is no "Normal" or "Utility" category
in the Amateur Built / Experimental class of aircraft. Those two
categorys apply to normally certificated aircraft.

Am/EXP aircraft operating envelopes are defined by the builder
during the test period. You may be safe flying at a higher
weight than 1600 lbs but there other considerations. How does the
airplane slow fly at a higher weight, is the approach speed adversely
affected, how does it stall, spin and all that other stuff. Are the
brakes adequate, is the prop correctly pitched to accelerate the new
mass. How is the climb rate..... Pulling G's is only a small part of the
picture.

Airplanes are systems, as such, messing with one data point cannot be done
without
evaluating the entire package for changes........
