Chapter 7: Aircraft Systems › Oxygen Systems › Servicing of Oxygen Systems
Servicing of Oxygen Systems Before servicing any aircraft with oxygen, consult the specific aircraft service manual to determine the type of equipment required and procedures to be used. Certain precautions should be observed whenever aircraft oxygen systems ... serviced. Oxygen system servicing should be accomplished only when the aircraft is located outside of the hangars. Personal cleanliness and good housekeeping are imperative when working with oxygen. Oxygen under pressure creates spontaneous results when brought in contact with petroleum…

Chapter 7: Aircraft Systems › Oxygen Systems › Pressure-Demand Oxygen Systems
Pressure-Demand Oxygen Systems Pressure-demand oxygen systems are similar to diluter demand oxygen equipment, except that oxygen is supplied to the mask under pressure at cabin altitudes above 34,000 feet. Pressure-demand regulators create airtight and oxygen-tight ... long hose that must be purged of air before 100 percent oxygen begins flowing into the mask. Continuous-Flow Oxygen System Continuous-flow oxygen systems are usually provided for passengers. The passenger mask typically has a reservoir bag that collects…

masks when operating at higher altitudes. Airplanes certified to older regulations had cannulas installed with an on-board oxygen system. However, current regulations require aircraft with oxygen systems installed and certified for operations above 18,000 feet to be equipped ... part of the pilot’s regular scan. Figure 7-44. Cannula with green flow detector. Diluter-Demand Oxygen Systems Diluter-demand oxygen systems supply oxygen only when the user inhales through the mask. An automix lever allows the regulators…

Chapter 7: Aircraft Systems › Oxygen Systems › Pulse Oximeters
Electrical Pulse-Demand Oxygen System Portable electrical pulse-demand oxygen systems deliver oxygen by detecting an individual’s inhalation effort and provide oxygen flow during the initial portion of inhalation. Pulse demand systems do not waste oxygen during the breathing ... demand method of oxygen delivery can reduce the amount of oxygen needed by 50–85 percent. Most pulse-demand oxygen systems also incorporate an internal barometer that automatically compensates for changes in altitude by increasing the amount of oxygen delivered…

Chapter 16: Cabin Environmental Control Systems › Oxygen Systems & Components › Gaseous Oxygen Systems
Oxygen Systems & Components Built-in and portable oxygen systems are used in civilian aviation. They use gaseous or solid oxygen (oxygen generators) as suits the purpose and aircraft. LOX systems and molecular sieve oxygen systems are not discussed, as current ... applications on civilian aircraft are limited. Gaseous Oxygen Systems The use of gaseous oxygen in aviation is common; however, applications vary. On a light aircraft, it may consist of a small Figure 16-8. This onboard oxygen generating system uses…
