* Condition: the Pack Outlet temperature is excessive. The crew has selected standby to acqire manual control of the pack output temperature. The INOP light remains illuminated. What is the system fault?
* Excessive high pack outlet temperature.
* Automatic Temperature Controller.

* If the Pack outlet temperature becomes excessive, will the PACK OFF lightilluminate in the Reset switch?
* No.
* Yes.

 Purpose of recirculating cabin air is to maintain the desired level of passenger cabin ventilation while minimizing the use of bleed air.
 False
 True

* Altitude setting should be made on LDG ALT during the Cockpit Preparation?
* 200 ft below take-off airport elevation
* Destination airport elevation
* Cabin altitudeas determined from placard

* The Left recirculation fan draws air through the forward E/E system and returns it to the mix manifold
* True.
* False.

* If a Pack Outlet temperature is excessive, how will the crew know if the fault is with automatic pack temperature controller?
* The INOP light remains illuminated upon selection of the Standby Mode.
* The INOP lightextinguished upon selection of the Standby mode.

* Since the Packs operate to maintain the temperature of the cabin zone requiring the lowest temperature, how are the other zones maintained at their desired temperature?
* Trim air is added to the air delivered to the other zones.
* The Packs modulate to deliver warm air to the other zones.

 The Left recirculation fan should NOT beturned off as this causes the overboard exhaust valve to latch open. Maintenance action is required to reset this valve.
 True
 False
