Centaurus queries about 'performance speeds' Sure they are not mentioned as such in POHs but in my experience most GA pilots do not fly the numbers to get max. performance from their aircraft. Typically speeds are +5 knots on those given in POHs. What Poteroo is saying is learn to accurately fly the aircraft using the numbers given to achieve max. 'performance' in the broadest context. Learning to fly a tail-dragger accurately using those 'performance speeds' will make you a much better pilot all round. I know it did for me. And in case you ask Poteroo has in excess of 10000 hours, the majority of which is in tail-draggers. He knows that of which he speaks - trust me.
