What about cowl flaps? All of my experience is with jets, what exactly are cowl flaps? For aircooled engines, the flaps either constrain the airflow into the engine compartment, or constraint it coming out of the compartment. The C172RG has them underneath behind the gear. Flaps are open at

Alex Perry writes: Hmm, I suppose I really ought to take some consideration of this into the CHT model. Are these a manually operated thing? It depends, of course. On the C172RG, it is a vertical moving lever just to the right of the elevator trim, with no automation. Newer aircraft

What about cowl flaps? All of my experience is with jets, what exactly are cowl flaps? JW Mine too. Cowl flaps are used to cool engines for ground operations,taxi, takeoffs and landings when the engine is either at a high power setting or there is insufficient airfow to cool the
