The conference proceedings deal with aircraft air supplies in current large passenger transport aircraft. Apart from the Boeing 787, all passenger aircraft utilize nonfiltered air (bleed air) drawn from the compressor stage of turbine engines to provide pressurization and breathing air. This design has been utilized since the 1950s and 60s. Synthetic jet engine oils and other fluids in aircraft systems are recognized and known to contaminate the bleed air supply, impacting flight safety, occupational and public health. The conference principal organizer was the Global Cabin Air Quality Executive (GCAQE), which was established in 2006 as a global coalition of health and safety advocates committed to raising awareness and finding solutions to poor air quality in aircraft. The conference program of the 2017 International Aircraft Cabin Air Conference included more than 30 oral and video presentations presented by scientists, doctors, pilots, cabin crew, engineers and experts from 11 countries covering a broad spectrum of topics. Most of these presentations are presented in these proceedings published first with the Journal of Health & Pollution. The topics include engine design and mechanisms of oil leakage, flight safety, occupational health and safety, regulatory issues, risk management, international actions, reporting, medical and scientific evidence, jet oils, filtration, air quality sensors, legal implications and causation.
