Description of Driving Event:
The OPF environmental control system (ECS) supplies conditioned air through ducts to the orbiter to purge and pressurize the forward/aft compartments and the payload bay. Over-pressurization could occur during ECS purge if the ventdoors are closed. No automatic monitoring and/or control exists to preclude simultaneous application of ECS purge air while all orbiter vent doors are closed, or to automatically relieve excess pressure under these circumstances.
