When you board an aircraft is there any smell or sign of the air being contaminated? Various terms used by crew and passengers worldwide to describe the smell (when present) include:
It is important to remember that smell descriptions vary between individuals and different chemical concentrations may result in significant smell variations. It is important to always remember that many chemicals, like carbon monoxide have NO smell. No smell does NOT mean no exposure. Your ability to smell goes within minutes so first impressions are important. The aircraft DO NOT have any form of contaminated air detection system. Many contaminated air events can be a faint background smell you will need to focus on to detect. Extreme events may result in misting in the passenger cabin.
A contaminated air event may occur at any stage of the flight and may be intermittent or constant.
