Hi all,
The aircraft I bought this spring is the first aircraft I've ever had with an exhaust gas temp gauge (one cylinder only, but better than nothing I guess): Cherokee with O-320.
I thought I had a pretty good handle on using it for leaning, but lately, now that I'm flying with hot outside air temps, I'm not so sure...
I expected that the exhaust gas temp shouldn't change much regardless of the OAT, but now I think I'm wrong, or else maybe my gauge is wrong...I am seeing peak lean temps waaaaay (75F +) hotter with the OAT at 90F, than with the outside air temp at 50F. Is this normal?
