They probably assume that you have transitioned from Vx or Vy climb to
cruise climb by the time you reach 3000 ft. I do this transition as soon as
I hit pattern altitude.

Hi everyone. I have a leaning question. The POH for my 152 says that the
mixture should be leaned to best power after passing 3000 feet in the
climb. However in other places in the POH (and the Lycoming site) they say
not to lean when at 75% power or higher in cruise. My question: Is the
engine developing less than 75% power during the climb; and is this why
leaning in the climb is OK? Does this guidance in the POH seem
contradictory to anyone except me?

Thanks for all your help.

Matt
