On the big jets, we stop at the gate, set the parking brake, check for
alternate electrical power, shutdown the engines, turn off the seatbelt
sign, wait for the signal that chocks are in place, and release the
parking
brake for heat dissipation.

I had known when the parking brake was normally applied on a transport jet,
but not when it was usually released--just not something I ever needed to
know.

Thanks,
