How does flap position affect fuel temp at the gate?
I've yet to partake in the running flaps-in-flare discussion yet at all, but this one is easy so I'll answer.
By retracting flaps during the flare, weight-on-wheels is reached earlier, thereby reducing TAT earlier as the aircraft slows. The fuel temperature upon shutdown at the gate will be lower on a landing where the flaps were retracted in the flare.
