cruise climb.
Best rate..........
Typical climb is 120-125 IAS, and even then its impressive. I try not to exceed 800-1000 fpm as it puts pressure on ATC to issue clearances......or me to stay below CTA, but lets say one day when Capt CM was at the stick ATC gave him a request to make at least 7000' by a certain time
I think they thought it was Jet powered! He was there by abeam YRED.
