Brake fans
I still have not read the definitive answer on this.
Interested in hearing more.
Putting the brake fans on just before the gate is too early in my opioion causing hot spots
Personally I prefer to wait and let brakes reach peak temperature let it rise to its peak then put the brake fans on or wait until after my preflight.
most wear occurs between 250 and 70 degrees correct ?
Sorry about the ramp guys but the carbon just comes out initially the initial blast .
