Another question in this context:
During training, we generally leaned only above 3,000ft.
At my current location, when I go flying, I rarely climb above 3,000 ft. due to airspace and frequent cloud.
Would it be a good idea to lean when cruising at, say, 2300 ft.?
From my understanding, the "fully rich below 3,000 ft" applies to the climb only and anything else is just a sort of safety precaution in the training environment?
