I fly year round and have flown in temperatures as cold as -23ºC. There are some members on here who have flown in even colder temps. Winter is one of the most beautiful seasons to fly in so don't be afraid to get out and fly keeping in mind some...
probably not a big detail, but sometimes, obstacle avoidance works fine when leaves are on trees and fails when the leaves are gone from thin branches
not that I've ever encountered that problem because I never screw up....uh huh
Be aware that icing can occur at air temperatures above 32 F surrounding the aircraft. It can happen on the props as well as the other surfaces of the aircraft.
