The aft cargo compartment temperature range is within which values?

• A. 60-80 F
• B. 50-70 F
• C. 70-90 F
• D. 65-75 F

Answer: (A)

Aft cargo compartment temperature is controlled to a specific operating window by the aircraft’s environmental control system. The standard range is 60-80 F (about 15-27 C) because this temperature span balances protecting a wide variety of cargo, keeping equipment and seals in good condition, and minimizing energy use. It helps prevent issues like condensation, moisture problems, or damage from extreme temperatures while still allowing practical loading and inspection on the ground. Other ranges fall outside the published tolerance, which could risk cargo quality or require unnecessary energy expenditure.
