The emergency oxygen supply, attached to the
seat pan bottom, is a self-contained unit that can
provide 50 cubic inches of breathing oxygen. It
can be operated either automatically (during
ejection) or manually. Automatic emergency
oxygen control is provided by a lanyard assembly
located on the underside of the seat pan left thigh
support and is connected to the catapult cartridge
manifold. During ejection, upward movement of
the seat provides automatic actuation. Manual
emergency oxygen control is provided by a
handle and pull ring located on the inboard side
of the seat pan left thigh support. An upward pull
on the handle provides emergency oxygen to the
pilot should the aircraft’s main oxygen system fail.
A pressure gauge, visible through a cutout on the

assembly, should indicate 1,800 psi (needle in the
black area) with a full bottle. The emergency
oxygen supply should last approximately 15
minutes, depending upon altitude and pilot
