Much, thank you.
80 degrees is very cold.![]()
Why would you assume that? If I had power available, I would be using it, rather than accept a descent. Cessna eliminated the 40 degree setting for a reason.
Didn't they get rid of the 40 degree setting to keep the airflow from buffeting the horizontal stab?
Oh sure, technicalities, but seriously, I've flown the hell out of 150s as has everyone else, and the things fly just fine with 40* of flaps, you just have to be careful. Yeah if you're in denver and its 95 out, you might have problems, but then the question arises, "why are you flying a grossly underpowered airplane in colorado in the summer?"

For this discussion there is a BIG difference between 'slowflight' and 'emergency procedures'
I do it almost every day as my part time job. Density Altitude at my field is usually over 9000 in the summer. And even on a cold day its hard to hold altitude with 30 degrees, I had a student sink last week over 500 feet with 30 degrees in a 172S 180 horsepower at full power. Now in AK, at sea level, when its cold you have WAY more performance! It feels like you have super turbo charger if you got used to flying in the Rockies at service ceiling density altitudes.
