Passage One
Questions 1 to 5 are based on the following passage:
The flight is fitted with independently mounted oxygen generators throughout the passenger cabin and crew areas. These generators supply oxygen masks that drop from compartments in the overhead panels. The masks are designed to be fitted over the nose and mouth. Once activated, each generator is capable of supplying a flow of oxygen to the masks that serves for a minimum of 15 minutes.
The passenger cabin masks are stored behind module doors above the seats. The doors are held closed by electrically operated latches. The latches are powered by the 115 V AC buses 1, 2, and 3. If the cabin pressure decreases below a value equivalent to the standard pressure at 14,400 feet, the latches release and the doors fall open, allowing the masks to drop. The doors can also be selected open by the pilots through a switch in the cockpit. The aircraft was equipped with 148 oxygen generators. There were three sizes of oxygen generators installed; each served either two, three, or four masks.
