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

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

Recall the normal and back-up fuel supply for the APU
VOL 2 7.4.3
- APU fuel is normally supplied from the right main tank
- Using crossfeed, fuel can be supplied from the left tank
- When center tank pumps are used to supply fuel to the APU (both pumps ON), a right main tank fuel boost pump should also be operating
- When center tank fuel value is less than 800 pounds, using center tank pumps alone
can force air into the APU fuel line and cause APU flameout or prevent APU start
APU start automatic delay
VOL 2 7.4.2
40” FOR INLET DOOR TO OPEN
APU bleed air is inhibited for… minutes after an APU start
VOL 2 7.2.1
2’ after APU start initiated
how the APU shutdown cycle is verified complete
VOL 1 5.7.2
Absence of APU info on SD ENG display
1’ after APU RPM decrease
Recall considerations for shutting down the APU both with and without External Power
available
vol 1 5.7.2
- With no external power, the BATT switch and EMER PWR selector must remain on
until APU shutdown is complete (absence of the APU information block on the SD
ENG display) - With external power connected, the EXT power switch must remain ON until APU
shutdown is complete (absence of the APU information block on the SD ENG display)
APU continues to run for approximately …seconds while a No Power Break
Transfer is performed
VOL 2 7.4.4
- At normal shutdown, APU runs 17 seconds while the elec sys do No Break Power Transfer (NBPT)
- This delay is bypassed when APU FIRE CONT toggle switch OFF & AGENT ARM position OR when the exterior ground APU toggle switch is SHUT OFF position
- It is also bypassed if an APU fire is detected
