Replacement of the yellow dixie cup

Abstract

The upgrade and improvement of life support systems has always been a priority for the United States Air Force. A study is currently underway to determine the feasibility of replacing the emergency passenger protective breathing device used on USAF transport aircraft. The present system, the "yellow dixie cup", provides supplemental oxygen in the event of a rapid decompression. The system is not designed to provide protection in the event of a fire or toxic fumes resulting from a cargo spill. The proposed replacement, utilizing either a positive pressure closed loop or filter based open loop system, will provide protection during any of these circumstances. In addition to personnel safety considerations, the Air Force continually strives to improve product reliability and maintainability. Approximately one third of the yellow dixie cups must be replaced annually, whether used or not. Specifications for the new mask include a requirement for an active five year shelf life. The effort, known as the Passenger Smoke and Fume Protective Device (PSFPD) study, is presently in the market survey phase, where the potential for buying an off-the-shelf item is under evaluation. This type of procurement, a Nondevelopmental Item (NDI) acquisition, is a highly cost effective method of meeting DoD needs. The market survey includes conducting evaluations to develop a performance-based specification to be used for the the procurement if a suitable replacement is found. The projected acquisition is planned for FY1995. The commercial aviation industry, which also uses the yellow dixie cup, has taken a great interest in the results of the study.<>
