Summary
| Description | In this film, the features and correct use of the type 14 pilot's mask and dilator demand oxygen regulator are detailed. The diaphragm of the regulator responds to the pilot's breathing. This action trips the oxygen demand valve and admits oxygen as the pilot's lungs demand it. When the regulator is set at normal, it admits air from the cockpit to dilute the oxygen and increase the oxygen endurance. The regulator switch is kept at the normal or on setting for most flight conditions. The internal mechanism of the regulator restricts the inflow of cockpit air as the plane gains altitude. At about 30,000 feet, no cockpit air is admitted, and the pilot breathes the pure oxygen that is necessary to sustain life atthat altitude. An emergency valve can be used to overide the system and supply pure oxygen on demand. A pilot is shown making a thorough pre-flight oxygen system check. A mechanic checks the system for leaks. The pilot takes off and illustrates the proper use of the oxyge |
