|
THE PACK TEMPERATURE CONTROL VALVE
|
CONTROLS THE QUANTITIY OF WARM AIR THAT IS MIXED WITH THE COOL AIR DOWNSTREAM OF THE AIR CYCLE MACHINE
|
|
|
WITH THE PACK TEMPERATURE CONTROL VALVE
|
THE PACK SUPLIES AIR AT THE TEMPERATURE OF THE ZONE WITH THE LOWEST SET TEMPERATURE
|
|
|
PACK HIGH FLOW AUTOMATIC SWITCHING IS INHIBITED WHEN
|
THE AIRPLANE IS ON THE GROUND OR
IN FLIGHT WITH THE FLAPS EXTENDED |
|
|
AUTOMATIC SWITCHING TO HIGH AIR FLOW OCCURS
|
BOTH ENGINE BLEED AIR SITCHES ARE OFF
APU BLEED SWITCHES ARE ON REGARDLESS OF FLAP POSITION AIR / GROUND STATUS NUMBER OF PACK OPERATING |
|
|
MAXIMUM AIRFLOW WHEN THE APU IS THE ONLY SOURCE OF BLEED AIR
|
ON THE GROUND
APU BLEED AIR SWITCH IS ON EITHER OR BOTH PACK SWITCHES ARE POSITION TO HIGH |
|
|
IF A PRIMARY PACK CONTROL FAILS
|
THE AFFECTED PACK IS CONTROLLED BY THE STANDBY PACK CONTROL IN THE OPPOSITE CONTROLLER

|
|
A PRIMARY OR STANDBY PACK CONTROL FAILURE CAUSES
|
PACK
MASTER CAUTION AIR CONDITION |
|
|
IF BOTH PRIMARY AND THE STANDBY PACK CONTROLS FAIL FOR THE SAME PACK
|
THE PACK CONTINUE TO OPERATE WITHOUT CONTROL UNLESS EXCESSIVE TEMPERATURE CAUSE THE PACK TRIP OFF
|
|
|
THE TEMPERATURE SELECTOR RANGE
|
18 C - 30 C
|
|
|
THE RIGHT PACK CONTROLLER
|
PRIMARY CONTROLLER FOR THE FLIGHT DECK TRIM AIR VALVE AND THE LEFT PACK CONTROLLER IS THE SECONDARY CONTROLLER
|
|
|
BECAUSE THE PACKS SUPPLY AIR AT THE TEMPERATURE OF THE COLDEST ZONE
|
THAT ZONE DOES NOT NEED TRIM AIR AND RELATED TRIM AIR VALVE CLOSED
|
|
|
THE OVERBOARD EXHAUST VALVE IS DRIVEN OPEN
|
IF EITHER PACK SWITCH IS IN HIGH OR THE RIGHT CIRCULATION FAN IS OFF
