A: between 5°C and 65°C
Q16: Which cargo compartment has heating capability?
A: Forward cargo only
Q17: What selections would you make on the overhead panel if you wanted to increase the temperature in the forward cargo?
A: Rotate the forward cargo switch to LO or HI. (FCOM1 2-3-19)
Q18: How many IASC do we have on the airplane?
A:2
Q19: What kind of valve is the engine bleed valve?
A: PRSOV
Q20: In the AUTO selection which controller controls the cross bleed valve?
A: Normally controlled by the IASC
Q21: What happens when the RECIRC AIR button is pushed and indicates OFF?
A:
1. It turns the recirculation fan OFF and:
2. If the AFT and FWD cargo switches are selected to OFF or VENT,the respective CARGO
SOV’S will go CLOSE.
3. If the FWD cargo switch is selected to LO or HI heat, then the CARGOSOV’s will remain
OPEN.
Q22: On the air synoptic page, what are the names of the two valves related to the Trim Air System?
A. TASOV and TAPRV
Q23: If the TRIM AIR switch is selected OFF, what becomes unavailable?
A: FWD CARGO heating is not available (so the FWD CARGO must be selected to OFF or VENT)
Q24: What is the purpose RAM AIR valve?
A: It provides emergency ventilation to cabin and cockpit at low altitude.
Q25: Which valve is controlled by the INLET pushbutton on the overhead panel?
A: The ground valve. (In OFF position also shuts off the FWD and MID supply fans)
Q26: What is the purpose of the ground valve?
A: It provides additional cooling to the mid equipment bay if the OAT is between3°C and 30°C {37°F and 86°F).
Q27: When does the ground valve close automatically?
A: The IASC closes the valve when all doors are closed and locked.
Q28: When does the ground valve open again automatically?
A: 1 min after touchdown
