One cabin air temperature sensor is located behind which seat?

• A. Behind the captain seat
• B. Behind the first officer seat
• C. In the cockpit near the ceiling
• D. Behind seat number 9

Answer: (A)

The main idea here is where the environmental control system samples cabin air to keep the cabin comfortable. A cabin temperature sensor should reflect the air that most occupants feel in the forward cabin. Placing it behind the captain’s seat puts the sensor in the forward cabin where it can monitor the temperature experienced by the crew and passengers in that area, while avoiding direct heat sources from the cockpit and equipment that could skew readings. If the sensor were behind the first officer’s seat or near the cockpit ceiling, it would measure a different zone (cockpit or another occupancy region) and wouldn’t provide an accurate sense of forward-cabin conditions. A position behind seat number 9 would be an arbitrary location not aligned with how the system samples cabin air. So, behind the captain’s seat is the placement that best represents the cabin environment for the control system.
