Beagle and rapiddescent, we mere mortals are on a lower plane than you chaps
Nope - we're all equals!
Our plane maxs out at 10,000, yours is/was somewhat higher.
The text book answer (Australia - civil) is/was min radius/max rate to be flown at Va and max "g", but recognising that power to sustain would in all likely hood not be available.
Beags, you are quite right in that your 150 had a g limit less than 6, the Aerobat version was beefed up for the aerobatic role.
