PASSENGER COMPARTMENT AIR DISTRIBUTION - DESCRIPTION/OPERATION
1. E R A
CS ETURN IR
A. Description/Location
Return air ducts and adapter assemblies have been added to the Environmental Control System
(ECS) on the left and right sides of the cabin. Return air from the main cabin circulates through an
opening between the Passenger Service Unit (PSU) and cabin headliner on each side of the
cabin.
Air ventilation holes have been added to the aft side of the forward wardrobe near floor level to
allow air to be drawn from the entry area. An air duct is installed to allow air to be drawn through
these air ventilation holes down into the existing ductwork. The air duct is located in the aft
outboard section of the forward wardrobe under an easily removed closeout box or closeout panel.
Air from the area near the smoke detector closeout is drawn through an existing manifold into a
duct assembly located outboard of the water tank.
B. Operation
The production-installed ECS equipment controls return air through the remaining ductwork. Refer
to the ECS Return Air Distribution graphic to view a layout of the return air modifications.
2. C A
ONDITIONED IR
A. Description/Location
New air conditioning ducts have been installed on the left and right sides of the aircraft at floor
level. Modifications include added duct assemblies to supply the cabin, aft lavatory, and baggage
areas. Conditioned air is delivered into the entry area through manifold assemblies that are
located at floor level in the lower galley assembly.
Conditioned air is also distributed through smaller ducts to the aft lavatory through vents in the
vanity kick panel, to the baggage area through a vent on the left-hand bulkhead, and to the water
tank compartment.
B. Operation
The production-installed ECS equipment controls distribution of conditioned air. For information
regarding cabin temperature control, see 21-61-18. Refer to the Conditioned Air Distribution

left- and right-hand gasper air ducts. Ancillary ducts distribute air to the pilot, copilot, jumpseat,
galley, and aft lavatory. Cooling air is also supplied to the main avionics compartment,
entertainment cabinet, and bulkhead monitors.
