Well.. I did investigate several gov publications but still almost got caught out when the examiner asked for a demonstration of recovery from unusual attitudes while under the hood... hadn't practised that for 12 years ! Maybe I overlooked it in my researches... He also decided to liven up the excersise... After the usual gyrations leaving the Seminol standing on its tail and on telling me to look at the instruments he began hammering me in the ribs repeatedly with his left elbow and shouting "TURBULENCE" over and over ! (He was built by the same people who built the Bay Bridge... about 6ft 3 and must have weighed 250 lbs !)
