"or.....is this a trick question"
HAHA. No, I just bought a PA23 Geronimo conversion and don't have any good numbers on it other than blue line is 95 mph. I want to see what it will do on one engine at 10K (probably driftdown) but was thinking blue line might only be accurate at sea level. I think the only way I'm going to get any accurate numbers on it is to go fly it.
