In the air conditioning system, how many temperature sensors are on the flight deck and how many are in the passenger compartment?

• A. Flight Deck 1; Passenger Compartment 2
• B. Flight Deck 2; Passenger Compartment 1
• C. Flight Deck 1; Passenger Compartment 1
• D. Flight Deck 2; Passenger Compartment 2

Answer: (A)

Understanding how the environmental control system senses temperature helps explain why there’s one sensor in the flight deck and two in the passenger cabin. The flight deck uses a single temperature sensor to monitor cockpit conditions and drive the cockpit climate control. In the passenger compartment, two sensors are used so the system can get a more representative picture of cabin temperature across different zones and loads. This arrangement lets the ECS regulate air flow and mixing to keep the cabin comfortable and avoid hot or cold spots, while keeping cockpit conditions steady with a dedicated, simple sensor. Having only one cockpit sensor but two cabin sensors provides the right balance between adequate cockpit control and accurate cabin regulation.
