Section III - SYSTEMS DESCRIPTION
PASSENGER SUPPLY
The emergency drop-out passenger mask unit consists of a mask and hose assembly and an
emergency mask stowage. The emergency mask stowage boxes are provided in the airplane ceiling
structure above the passengers' heads and supply oxygen to the single face masks. The stowage
opens automatically or manually and allows the mask to drop into the
half hang position during an
emergency.
The mask has a lightweight molded face-piece which can be held against the face with one hand. Metal
plates on either side of the base give it support and secure a filter. The mask supply hose assembly
consists of two hoses joined by the flow indicator. When the mask is in the stowed position, the flow
indicator is held in the carrier clip in the stowage box. In this position the check valve in the flow indicator
is held closed and prevents flow of oxygen.
