I know several airlines have the policy on CRJs of only raising flaps to the takeoff position in order to reduce wear. Perhaps US has adopted this for the whole fleet.

Airbus recommends that flaps be left in Config 1 on the ground when the temperature is over 100F (37C). There's an issue where a bleed leak sensor "overheats" when the slats are retracted and it kicks out a wing bleed leak warning in the cockpit.

Here in "sunny" Europe we tend to go with above 30C.

The CRJ had different reasons for doing that---mainly to do with possible flap disagreement; however, the entire CRJ fleet should've finished fitting out flap disagree sensors years ago.
