Leaning at Take-Off
Two questions to all of you who have high-altitude airfield experience.
My understanding is that you should lean your mixture when departing a runway that is at an altitude, or has a density altitude, greater than 5,000ft (see edit below). Is this correct? I have read the Cessna 172 POH but cannot see anything on the subject.
EDIT: I just found it in the POH, section 4-14, although it states 3,000ft and not 5,000ft.
Secondly, I was taught to lean before or at the power checks, but have been told that for cooling reasons it is best to lean during the take-off roll. Does anyone have a preference or an idea of which method is preferable?
