APU max operation Temp: 52 degrees Celsius/125.6 degrees Fahrenheit.

175 has a few max temps, but mostly cold temperature limitations. None that would create an issue from an operational standpoint in Phoenix.

Unless you’re referring to some potential performance issues in hot weather? Single engine climb gradient issues? It does have a tendency to climb like a dog in the summer.

you ready? *eye roll*
ISA is 13 degrees at 1000'MSL based on the ambient temperature lapse rate of 2 degrees/1000 ft. Add + 35 = 48 C which is 118.4 F. Ops prohibited that day, and several others.

The “you ready” was in reference to the “fun fact” , but yeah take in personal. *eye roll*

So the hottest day in the history of Phoenix summers was 122 F, 30 years ago, and you’re trying to tell me we can’t have a 175 base because the max temp is 118.4 F?
