again, heat soak is not a part of the DA. you are confusing a hot engine with an engine in a hot area.
DA is calculated by elevation, humidity, temperature, and barometric pressure. those four factors and those four factors alone
and lower DA does not necessarily mean lower IAT
Example:
0 elevation
31 in Hg barometric pressure
0% humidity
60*F
equals -1149 DA
0 Elevation
29 in HG
95% humidity
60*F
equals 1350 DA
same elevation, 2500 difference in DA, but you will get the SAME IAT's.
again... try playing around with a DA calculator... you might learn a thing or two.
