The other cabin air temperature sensor is located behind which seat?

• A. Behind the captain seat
• B. Behind seat number 9
• C. In the cockpit
• D. Behind seat number 3

Answer: (B)

Cabin temperature sensing relies on more than one measurement point to keep the environment comfortable. The other cabin air temperature sensor is placed behind seat nine because that position samples cabin air representative of the main passenger area, away from the heat and airflow influences of the cockpit and the immediate vent flow. This helps the environmental control system form a balanced view of cabin temperature and adjust heating or cooling accordingly. Placing a sensor behind the captain’s seat or in the cockpit would bias readings toward the flight deck, and the rear, forward-forward position behind seat three isn’t the published location for this sensor.
