A320 Parking Brake Stuck On on departure
Hi
Just had an A320 sat on the active runway with parking brake stuck on. All CBs pulled, Hydraulics cut, Eventually engines off and complete down power. Poor captain was very cool but must have been having a fit! Powered back up, BSCU test failed..Hit brake pedals repeatedly and parking brake switch many times..Brakes released. Engine on and taxi back to stand to clear Hanoi's active runway..It CAN happen..We will see what the fix was tomorrow..Phew!
An Engineering perspective..
