What is Aerotoxic Syndrome?

The term Aerotoxic Syndrome describes acquired acute & chronic ill health caused by exposure to toxic oil fumes present in the breathing air of most commercial jets. Unaware, thousands of people suffer every day, without knowing about this hidden health and safety hazard.

A US doctor and scientists from France, Australia were the first to identify Aerotoxic Syndrome in 1999. The hidden illness is known to affect the central nervous system and brain, causing a range of acute symptoms and long-term ill-health in around 30% of all flyers.

An oil fume event was photographed by passengers on a flight from London Heathrow to Valencia in August 2019. The full account of the incident can be found here.

Captain John Hoyte

Captain John Hoyte

John is a career pilot who began flying in 1976 with a varied international flying teaching career but ceased flying BAe146’s jets prematurely after 16 years because of increasingly severe neurological & physical symptoms with ‘Chronic stress’ in mid-2005.

In early 2006, John was tested by University College London (UCL) along with 26 other British Airline Pilots Association (BALPA) pilots, 100% of whom showed evidence of Toxic Air exposure, which was later published by Dr Sarah Mackenzie Ross of UCL.

John founded the Aerotoxic Association Ltd. Charity in 2007 to help support other survivors (both aircrew & passengers) and to work with international groups such as the Global Cabin Air Quality Executive (GCAQE) which was formed in 2006 to counter the still existing formal position of ‘No positive evidence’ by governments and industry.

Many international professional groups now work for the formal acceptance of Aerotoxic Syndrome as an Occupational Disease, the illness was first defined in 1999 by a US doctor, a forensic scientist from France and an Australian toxicologist and for the urgent introduction of the known and now available technical solutions such as filtration and monitors which is in the public interest.

John has published evidence, which is in the public interest of anyone who flies in unfiltered & unmonitored bleed air jets on since 2007. He has recovered most of his previous excellent health due to pioneering Simulator Flying and other public flight entertainment systems from 2015-2019 and now holds a Class 2 Aviation medical certificate and looks forward to return to his lifelong passion of flying.

John has helped fund & produce educational films and published books on Aerotoxic & his flying career.

John recently presented the Associations/Unions ‘Wish list’ for some of the 1.5 million Euros for ‘Further research’ into toxic cabin air to Airlines, Manufacturers, Researchers & Regulators at EASA’s (European Union Aviation Safety Agency) first ever ‘Cabin Air’ workshop in Cologne, Germany in January 2020.

If you are interested in professional consultation into any aspects of aerotoxic syndrome, please contact John at – but please note that he is NOT medically or legally qualified to offer medical or legal advice or treatments, which are carried out by other specialist experts.
