Even the non Aerobat150/152 is cleared for spinning, so is the 172 as long as they are loaded within Utility Cat limits. All are +4/-1.76g. The Aerobat is+6/-3g
Nope, my 172 FR172K is clearly placarded and stated in the manual as not permitted for intentional spinning.
Many of the common types in the GA fleet are not cleared for spinning either.
This is the point I have been trying to make, spinning is an exercise that is pointless to teach to the general spam can flyers. Avoidance is a much better thing to teach and thankfully those who make the rules world wide seem to agree for a change.
Just because we had to do it and it 'separated the men from the boys' does not make it a good thing. Personally I think it is one of the few steps forward displayed by regulators who are normally backwards thinking.
