I know cold air is better for engine performance in general, colder air is also denser making lift components stronger(from what I understand).
I was just wondering if there is a temperature or a range of temperatures that offer the best performance overall?
Is there a temp that covers all areas such as takeoff/climb performance, cruise etc. or is it something where each performance area has its own "sweet" spot?
Let's use common flight trainers like the C172 as the example.
