I see.
That explains a few things. On the legacy CAL side, I flew the 76 400 allot. Never had a concern over brake temps. Heck, One time I even used max auto. No problem.
I do notice the 76 300 gets brakes temps up to 4 and 5 with just auto brakes 1. This may explain why I fly with allot of L UA guys that use brakes zero (off). The only thing I can rationalize is that the brakes are steel instead of carbon.
Whenever I land a 300 with brakes one I get elevated brake temps. When I land with brakes zero (off) I have no perceivable issue with brake temps.
When light, after burning off the fuel it likes to taxi fast so I do need to get on the brakes a bit as I go from the runway to the gate. So that doesn't help either.
I think I will land with brakes zero (off) for a while and try that if weather and runway conditions permit.
