AIR6.20.15 With the ISOLATION VALVE switch in AUTO, the isolation valve _________ if either engine BLEED air or air condition PACK switch is positioned OFF. automatically opens automatically closes nothing occurs.
AIR6.20.16 The Wing-Body Overheat (OVHT) TEST switch _____________. tests wing-body overheat detector circuits illuminates both WING-BODY OVERHEAT lights all answers are correct.
AIR6.20.17 Conditioned air for the cabin comes from _________________. either the aircraft air conditioning system or heat exchanger located in the balance bay either the aircraft air conditioning system or a preconditioned ground source ram air.
AIR6.20.18 Conditioned air from the ______, upstream of the mix manifold, flows directly to the flight deck. left pack right pack APU pack.
AIR6.20.19 Air from the left pack, air from the right pack, and air from the recirculation system is combined in the ________. mix manifold aircraft cabin the lavatory.
AIR6.20.20 The APU can supply air for ________ on the ground for all operations the left pack only the right pack only two packs.
In flight with the air conditioning PACK switches in AUTO and both packs operating, _________. the packs provide “normal air flow” the packs provide “high air flow” the left pack provides “normal air flow” and the right pack provides “high air flow”.
the left pack provides “normal air flow” and the right pack provides “high air flow” the operating pack provides high air flow automatically, if the flaps remain retracted. the operating pack provides low air flow the operating pack shuts down above FL250.
AIR6.20.23 The ram air system is used to provide cooling for the __________ in the air conditioning systems. heat exchangers hydraulic pumps APU.
AIR6.20.24 In a B737-800, what happens if an amber ZONE TEMP light illuminates? the MASTER CAUTION light will illuminate, and the pack valve will go full cold the MASTER CAUTION light will illuminate, and both packs will trip off the MASTER CAUTION light will illuminate, and the trim air valve closes.
AIR6.20.25 The recirculation fan system __________ the air conditioning load and the engine bleed air demand. reduces increases has no effect on.
AIR6.20.26 What makes the equipment cooling OFF light illuminate? placing the equipment cooling fan in alternate loss of air flow due to failure of an equipment cooling fan loss of the left pack in flight.
AIR6.20.27 The TRIP RESET switch resets the ______________. BLEED trip OFF, PACK trip OFF DUCT OVERHEAT on the B737-700, or the ZONE TEMP on the B737-800 all answers are correct.
AIR6.20.28 On the B737-800, illumination of the PACK, MASTER CAUTION, and AIR COND annunciators during recall indicates _____________. a pack trip off or a failure of the primary or standby pack controls a pack trip off and the valve has driven to full hot all answers are correct.
