i think the ? is expatula, if for some bizarre reason some numb nut set the parking brake which is only a switch on the airbus will the ecam give a warning to say such.
whereas the boeing and i speak only from 737 experience you have to press the toe brakes and then set the parking brakes.
i also would like to know considering the ? is asked, will you get a warning on the airbus if the park brake is inadvertantly set in flight?
