A cylinder head temperature indicator shall be provided for each engine on airplanes equipped with cowl flaps. But there are a number of other factors that also affect CHT. I very seldom refer to EGT when I lean my engines; I use fuel flow to get somewhere in the ballpark, and then fine-tune by reference to CHT. For Bonanzas and Barons, a reasonable rule-of-thumb is that optimum engine longevity is achieved by limiting CHTs to 380F. CHTs above 400F should be considered abusive, and grounds for doing something right now to bring them down. The CHT gauge on a TCMengine usually has a green arc from 200F to 460F, with a red-line at 460F.
