Compartment temperature controls set cabin temperature to Between 65F (C) and 85F (W) when in Auto mode Between 60F (C) and 80F (W) when in Auto mode Between 65C (C) and 85C (W) when in Auto mode Between 65F (C) and 85F (W) when in Manual mode. Pack control selectors have the following modes Off, Auto, Standby Normal, Standby Warm Off, Man, Standby Normal, Standby Warm Off, Auto, Standby Cold, Standby Hot Off, Man, Standby Normal, Standby Warm. Which of the following are automatic? (Check all that apply) Pack control Fault detection Overheat protection Temperature control. How many temperature control zones are there? 1 2 3 4. When an automatic control system fault is detected The pack will continue to operate in a degraded condition, requiring crew interaction. The pack will shut down automatically, requiring crew interaction. The pack will continue to operate in a degraded condition, not requiring crew interaction. The pack will shut down automatically, not requiring crew interaction. . When a pack outlet overheat is detected The pack will continue to operate in a degraded condition, requiring crew interaction. The pack will shut down automatically, requiring crew interaction. The pack will continue to operate in a degraded condition, not requiring crew interaction. The pack will shut down automatically, not requiring crew interaction. . If an internal pack overheat is detected The pack will continue to operate in a degraded condition and the pack valve will close The pack will shut down automatically and the pack valve will close The pack will continue to operate in a degraded condition and the pack valve will open The pack will shut down automatically and the pack valve will open . Pack controllers regulate the pack output air temperature to satisfy the requirements of the compartment requiring the Coolest air Warmest air Biggest temperature change Most air conditioning. Trim are is Hot and from the bleed air system Cold and from the bleed air system Hot and from the air conditioning system Cold and from the air conditioning system. Packs control the temperature of the ______ compartment. ______ trim air is added through trim air valves to control the rest Coolest, Hot Coolest, warm Hottest, cold Hottest, warm. When an internal pack overheat is detected The pack valve closes, the pack shuts down The pack valve closes, the pack goes to manual The pack valve opens, the pack shuts down The pack valve opens, the pack goes to manual .

Equipment coming selector STBY (check all that apply) Positions cooling system for inboard airflow Positions cooling system for outboard airflow Positions cooling system for reverse airflow Shuts down the nitrogen generation system. Equipment coming selector OVRD (check all that apply) Positions cooling system for inboard airflow Positions cooling system for outboard airflow Positions cooling system for reverse airflow Shuts down the nitrogen generation system. FWD EQPT OVHT indicates (Check all that apply) Low airflow High airflow Low temperature High temperature . FWD EQPT OVHT indicates High temp or low airflow Low temp or high airflow High temp or high airflow High temp and low airflow. Cargo heat system provides heat to the FWD, AFT, BULK cargo compartments FWD, AFT, MAIN DECK cargo compartments FWD, AFT, BULK and MAIN DECK cargo compartments AFT, BULK and MAIN DECK cargo compartments. Cargo heat system provides heat to the (Check all that apply) FWD AFT BULK MAIN DECK. FWD and AFT cargo compartments are usually maintained at 45F / 7C 32F / 0C 0C - 7C 2C - 22C.
