Actually untrue. Most instructors and check airman believe that manual brakes and full reverse have their place in our operation, especially in BOG and SJO with a tailwind on final in a 320 with no brake fans. It's all part of a de-mystifying movement with the 320; the Carlson days of micromanagement are gone. You're typed and qualified and smart enough to decide on your own how you would like to get rid of your energy.
