I am a student pilot. I bought a 1964 180B. I have done 5 flights in it so far and am solo'ing it. I am scheduled to do a night XC if the stars can ever align (wx, CFI, schedule) and need to figure out the time to the top of climb, gph, etc. On the 172 I was training in they had some great charts and graphs for all this. Not so much for the flight manual that came with my 180. Does anybody know where I can find data like this? Maybe from a more modern but similar Cherokee 180 with the Hershey Bar wing? Thanks for the help!
