During ground operation, when in icing conditions and the OAT is +3ºC or less, the following procedure should be applied for ice shedding:
(While stationary)
-Accelerate engines to 50% N1 for 5 seconds at intervals not more than 60 minutes.
Maintenance action on the brakes is necessary if:
-Temp diff between 2 brakes of a gear >150ºC and one of them is >600ºC, or
-Temp diff between 2 brakes of a gear > 150ºC and one of them is at or below 60ºC, or
-Difference between the average temperature of the left gear brakes and right brakes is >200ºC
-THE TEMP OF ONE BRAKE EXCEEDS 800ºC
Brake Fans use
I short turnaround or if any brake is likely to exceed 500ºC, use without delay. Otherwise, delay to 5’ after landing or entering gate, whichever happens first
