An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine will assess the health and safety impacts of temperatures in the passenger cabins of airlines operating under a Part 121 certificate of the Federal Aviation Administration.
Specifically, the committee will:

• Identify and review available data from Part 121 operators on cabin air temperatures and available evidence on potential health and safety impacts on passengers and cabin crew members.
• Review existing standards on safe air temperatures and humidity levels in enclosed environments intended for public occupancy and consider their applicability to ensuring the health and safety of occupants of aircraft operated by Part 121 airlines.
• Examine the feasibility of applying identified temperature and humidity standards to aircraft cabin environments, considering input gathered from aircraft manufacturers.
• Seek input from Part 121 operators, aviation labor organizations, and other interested parties on health and safety impacts of cabin temperatures.

Based on this review, the committee will develop a short consensus report with its findings and conclusions, and, as appropriate, recommendations to inform strategies for monitoring, assessing, and managing passenger cabin air temperature levels and any associated health and safety impacts.
