Hello,
A sample best power mixture range graph mentions to add 0.6 NM for each degree Celsius above standard temperature and subtract 1 NM for each degree Celsius
below standard temperature. This is what I do not understand. I was under the impression that with hotter temperatures an engine becomes less efficient and produces less power and hence less range. Or to put it differently, I was under the impression that most aircraft have the best range with higher density altitudes. I know ultimately range depends on L/D max but my question is what is indeed the effect of temperature and altitude on range? Thank you :-)
