The second cabin air temperature sensor is located behind seat number which?

• A. Behind seat number 9
• B. Behind seat number 3
• C. Behind seat number 1
• D. Behind seat number 12

Answer: (A)

Cabin air temperature sensing relies on reading representative cabin air to avoid readings that are skewed by nearby heat sources or direct airflow. The second sensor is placed in a location that samples ambient cabin air away from heat hot spots, vents, and heavy occupant concentration to provide a reliable, redundant measurement. By positioning it in a mid-cabin area where air mixes more uniformly, the system gets a reading that reflects the overall cabin temperature rather than a localized hotspot. The exact seat behind which this sensor is installed is specified in the aircraft’s cabin layout and maintenance documentation, so refer to that diagram to locate the precise position.
