Area of Science:

  • Aviation Medicine
  • Environmental Health
  • Occupational Health

Background:

  • Increasing reports of crew and passenger health complaints on commercial flights.
  • Symptoms include fatigue, headache, and respiratory issues, particularly on long-haul routes.
  • Concerns exist regarding contagious disease transmission and potential links to cabin air quality.

Purpose of the Study:

  • To investigate the causes and effects of illness contracted inflight.
  • To review factors potentially impacting cabin air quality.
  • To identify potential resolutions for cabin air quality issues.

Main Methods:

  • Review of cabin air quality aspects: volatile organic compounds (VOCs), carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), particulates, and microorganisms.
  • Examination of the aircraft cabin ventilation system.
  • Analysis of potential confounding factors: barometric pressure, hypoxia, humidity, circadian rhythms, and work/rest cycles.

Main Results:

  • The paper reviews various airborne contaminants and environmental factors within aircraft cabins.
  • It explores the role of the ventilation system in maintaining air quality.
  • It considers other inflight environmental stressors as potential causes of illness.

Conclusions:

  • Cabin air quality is a complex issue influenced by multiple factors.
  • Further research and improved ventilation strategies are needed to address crew and passenger health concerns.
  • Recommendations for resolving cabin air quality issues will be provided.
