Original Flight Hardware: Passenger Oxygen

The passenger oxygen system on the Lockheed L-1011 is a continous flow chemically generated oxygen system. The oxygen is the product of a chemical reaction which takes place inside a canister. The canister components are:

Electric initiator
Sodium chlorate block and iron powder
Exit filter
Insulation layer
Stainless steel container

Once the chemical reaction is started, it cannot be stopped until the reacting agents are depleted.



The panel itself has only two front elements, however the inside of the panel has control and test elements for the entire passenger oxygen system. The front panel control elements are:

OXYGEN FLOW LIGHT ... illuminates to indicate that all passenger oxygen generators have been activated.
MANUAL CONTROL SWITCH ... momentary switch, which when depressed, immediately startes the sequence activation of the oxygen generator and mask groups.

Original Flight Hardware: Oxygen Regulator Deman

Crew oxygen on the Lockheed L-1011 is provided form an central source and controlled by a diluter demand regulator mounted at each crew position. Actually, there are a total of 5 oxygen masks in the Lockheed L-1011 cockpit; 3 for the crew and two for the observer seats.

The Oxygen Regulator has the following components:

FLOW ... an window that indicates the flow of oxygen.
REGULATOR OXYGEN PRESSURE ... The line pressure of the oxygen supply.
SUPPLY ... opens the valve from the supply line to the oxygen regulator.
100% OXYGEN and NORMAL OXYGEN ... switches the dilution of the oxygen supply from pure to mixed.
EMERGENCY, NORMAL and TEST MASK ... Sets the oxygen regulator mode.



Panel Location

The 3 panels for the crew are obstructed by the two forward facing crew seats an by the work desk below the flight engineer panel.
