STUDENT GUIDE FOR T-1A AIRCRAFT SYSTEMS
Each of the quick-donning diluter masks is also equipped with smoke goggles compatible with
the masks. These smoke goggles are designed to be donned over the oxygen mask and rest on
the mask nosepiece.
Passenger Oxygen Subsystem
There are seven passenger masks located in the headliner throughout the cabin. Five masks are
located in the passenger seating area and two in the lavatory. Oxygen supplied to the passenger
masks is a constant flow of 100% oxygen. If the cabin pressure exceeds 12,500 + 500 feet, the
passenger oxygen system is automatically charged and the masks are deployed. Manual
deployment of the masks can be accomplished by pulling the PASS OXYGEN control knob. To
begin oxygen flow to the mask, users must pull the lanyard cord attached to the supply valve in
the overhead container.
