... Aircraft air quality incidents are often traced to jet engine oil and/or hydraulic fluid leaking into bleed air used to ventilate the cabin. These contaminants can be subjected to temperatures in excess of 500°C. Exposed flight crew members have reported symptoms including dizziness, nausea...

... AlliedSignal Aerospace, the manufacturer of the propulsion engines and auxiliary power unit of the BAel46 airframe performed air quality testing in cooperation with the airframe manufacturer, British Aerospace and the customer, Ansett Airlines to identify possible air contaminants entering...

... A passenger comfort survey was conducted with a major U. S. airline with the objectives to determine: 1) the variables that affect passenger comfort, including air quality variables; 2) the level of passenger comfort during flight and whether passengers are experiencing specific types of health...

... of contaminants in buildings. The program enabled simultaneous dynamic simulations of contaminant distribution, airflows, and temperatures in a multizone building. Using the new program, the dynamic distributions of contaminant concentration and air quality in an example building were determined with and without...
