Cabin Temperature Monitoring – It’s about Safety!

Date: July 16, 2021

We recently published information about reporting 2HOT2COLD issues on the airplane and the serious dangers an overheated aircraft cabin can pose to the safety and health of both Flight Attendants and the passengers in our care.

A hot aircraft can cause fatigue, dizziness, nausea, and in extreme cases, could escalate to the point of heat exhaustion or heat stroke. Based on our experience, we know immediately when we first board an aircraft to begin our safety checks if the temperature is extreme and if action needs to be taken to adjust it.  Zone control should be made aware that the aircraft cabin temperature needs adjustment.  If the pilots are on board the aircraft, you should alert them to your concerns.  If not, notify the purser who will take the initiative to notify Zone Control in a polite, but firm manner, of their concerns about the cabin temperature.   Alternatively, using the newest, available functionality, she/he may use the chat function on the Link device (Flight Info) to communicate this information.   In the interest of safety, be certain that zone and the gate agent are made aware, at the earliest opportunity, that you believe the aircraft temperature is unsafe for boarding.

In advent of the COVID-19 pandemic, all aircraft having three hours or less of actual ground time should have the APU running to maximize airflow through the aircraft HEPA filtration systems in order to prevent the spread of COVID-19.   Because of this policy, we expect that the number of instances of overheated aircraft should be limited.  However, keep this information in mind as you express your concerns and advocate in the interest of all concerned and use it judiciously in the course of your advocacy.
