EMER LT Switch
VOL 2 1.4.3
OFF – Extinguishes emergency lights
(emergency battery packs are being charged)
ARM - Normal position (emergency battery
packs are armed)
ON - Activates emergency battery packs to
illuminate emergency lights
LANDING LIGHTS SWITCHES
VOL 2 1.4.2
Lim: cool 1 ½ minutes after the initial
extension or retraction and 3 ½ minutes
after each subsequent extension or
retraction
not be operated in
still air for more than 10 minutes
Auto retract if eng fail
auto re-extend flaps=>25
PREFLIGHT considerations for center tank fuel pumps
vol 1 2.1.11.6
Prior to engine start on any flight where center tank fuel is present and will be needed
for that route segment, the center tank pumps must be individually checked to verify pump
operation
AIR CONDITIONING PACK INDICATION
VOL 2 2.1.5
White – Commanded OFF, no air flow
Green (vaned) - Commanded ON, normal air flow
Amber – Commanded OFF, normal air flow
Amber (vaned) - Commanded ON with no air flow
AVIONICS COOLING Switch
VOL 2 2.1.1
The AVIONICS COOLING Switch is operative in flight only and is used to control radio rack cooling:
FAN - the primary fan cools the radios; if the primary fails, the backup fan comes on automatically
OVRD - the radio rack fans are off, the venturi valve is commanded open and venturi airflow cools the radios
NOTE: On the ground, both fans stay on all the time and the venturi valve is
commanded closed
RAM AIR SWITCH
VOL 2 2.1.1
OFF - Ram air valve commanded closed
ON - Ram air valve commanded open, allowing ram air to enter the air conditioning ducts
In flight, the system provides ventilation for the cabin and the cockpit when air conditioning is not available
Do not use the ON position to ventilate the aircraft on the ground
PACK SHUTDOWN Switch
VOL 2 2.1.1
AUTO - Allows automatic pack shutdown in the event of an engine failure
OVRD – Overrides the auto pack shutdown for an engine failure OR when the packs are selected OFF on the FMC
- Both AC packs will automatically shut down if either engine fails during takeoff OR if selected OFF through the FMS
- The auto pack shutdown feature is disarmed above 3000’ AGL
NOTE: A pack will also auto shutdown if a high supply duct temperature is sensed. This cannot be overridden with the PACK SHUTDOWN switch.
FLOW Switch
VOL 2 2.1.1
NORM – The flow control valve solenoid is energized to provide a lower airflow rate
HIGH - The flow control valve solenoid is de-energized to provide a higher airflow rate
must be in NORM for takeoff
ISOL Switch
VOL 2 2.1.1
CLSD - The isolation valve is commanded closed
OPEN - The isolation valve is commanded open
AUTO - The isolation valve is controlled by the pneumatic system controller. Allows automatic crossfeed of left and right pneumatic systems during one bleed
source operation with airfoil ice protection selected ON
Instrument Panel Flow Indicator
VOL 2.1.2
ON – On the ground, with air conditioning off, indicates instrument panel cooling fan airflow
OFF – On the ground, with air conditioning off, indicates the absence of airflow and cooling fan failure
1 only during ground and flight operations with both air conditioning packs off
2 ground operations, one pack selected AUTO, the instrument cooling fan operating. With both packs selected AUTO, the instrument panel cooling fan is not operating – instrument cooling provided by aircraft air conditioning system
3 ground operations, if the APU is required for cooling and both pilots must leave
the cockpit, one AC pack should be selected OFF. This will preclude possible Display
Unit overheats caused by an inadvertent APU shutdown with both packs selected on
4 flight operations, BOTH AC packs must be OFF for the instrument panel
cooling fan to operate
Gasper Booster Fan switch
VOL 2 2.1.3
ON (Push) – Provides supplemental airplane ventilation when the left pack is
operating
OFF – booster fan is not operating; switch is extinguished
NOTE : The fan increases cold air ventilation through the eyeball outlets. In flight with both packs off, the ram air valve should be manually selected to ON (open).
CAB PRESS SYSTEM INDICATOR
VOL 2 2.1.4
SELECT - Illuminates to indicate failure of both automatic cabin pressure controllers.
MANUAL - When switchlight is pushed, MANUAL illuminates and the cabin pressurization system operates in manual mode. Also used to alternate control between cabin pressure controllers (Auto 1 and Auto 2)
Air Conditioning T/O Packs Off procedure
VOL 1 5.2.2
TO/APPR page PACKS – Line select ON to OFF PACKS ALL OFF alert message on EAD
NOTE: With the air conditioning pack switches in AUTO, the packs will automatically shut off at
throttle advance and will automatically come back on at 3,000 feet AGL
How forward and aft cargo bins are heated and where live animals must be
transported
VOL 2 2.2.17
-In flight, if the primary fan is operating, the forward cargo compartment is electrically
heated to a temperature range between 60° and 75°F
- Live animals must be transported only in the forward cargo compartment
- The aft cargo compartment is heated with cabin exhaust air
Recall the function of the Pneumatic Overheat Detection System (PODS)
VOL 2 2.2.6
- Detects overheat conditions in the tail compartment AND along the wing and tail ice protection manifolds
- If a failure is detected in the anti-ice manifolds, PODS automatically closes the respective anti-ice valve and alerts the flight crew
- PODS is automatically tested when the engine fire test is performed
WING/TAIL A/I BLEED AIR INDICATIONS
VOL
Blank – Anti-Ice off
White – On the ground, anti-ice is
commanded on or anti-ice is commanded off with system pressurized
Green – Anti-ice commanded on in flight
Amber – Anti-ice bleed air temp out of limits
Recall conditions which require the use of engine anti-ice
VOL 1 5.16.2
OAT is 6ºC or below (10ºC TAT or below in flight) and any of the following conditions exist:
1- Visible moisture (clouds, rain, snow, sleet, ice crystals, fog when visibility is 1 mile or
less, etc) is present, or
2- 3ºC or less temperature/dew point spread, or
3- Ice, snow, slush or standing water is present on the ramps, taxiways or runways
Recall engine run-up requirements during icing conditions
VOL 1 5.16.2.5
Run the engines to a minimum of 40% N1 for approximately 10 seconds at intervals
no greater than 60 minutes
Additionally, a standing takeoff is required during icing conditions and is
accomplished by holding the brakes while in position on the assigned runway until
the engines are stabilized at, or above, 50% N1 before the start of the takeoff roll
AIR DATA Heat pushbutton
VOL 2 3.1.2
OFF (amber light) – all air data system heaters are off
Dark when all heater circuits for pitots, rudder limiter, stall probes, static ports,
and RAT probes are energized
NOTE: RAT probe heat is inhibited during ground operations
WING ICE DET switch
VOL 2 3.1.2
RESET – resets system and removes WING ICE DETECTED alert from the EAD. System will not reset if ice remains on the sensors
TEST – tests the wing ice detection system
Wing ice detection system functions on the ground only and alerts the pilots to the presence of wing upper surface ice. It is
inhibited during takeoff, landing and in flight
Do not takeoff with WING ICE DETECTED alert displayed
