Thanks, it is true. There is also a safety aspect to the use of autobrakes. At cold temperatures the carbon brakes are like sheets of untreated glass, they slide right over each other. Heat helps the materials grip each other.

I try to remember to let the First Officers taxi on a cold morning, just to see how little braking force is available with cold brakes. On the 321 a pilot can pretty much go to the floor and get a smooth stop. It is good for a pilot to know and realize, especially when we want to taxi to, but not past, a hold short line.
