A

heat exchangers

24
Q

In a B737-800, what happens if an amber ZONE TEMP light illuminates?

the MASTER CAUTION light will illuminate, and the trim air valve closes

25
Q

The recirculation fan system __________ the air conditioning load and the engine bleed air demand.

A

reduces

26
Q

What makes the equipment cooling OFF light illuminate?

A

loss of air flow due to failure of an equipment cooling fan

27
Q

A

all answers are correct

28
Q

On the B737-800, illumination of the PACK, MASTER CAUTION, and AIR COND annunciators during recall indicates _____________.

A

a failure of the primary or standby pack controls

29
Q

If both primary and standby pack controls fail for the same pack _________.

A

the pack will continue to operate without control unless excessive temperatures cause the pack to trip off

30
Q

Cabin pressurization and ventilation is controlled by?
