BAGGAGE VENTILATION SYSTEM
Airplanes equipped with “class-C” baggage compartment have a
Baggage Ventilation System installed. Although no dedicated
temperature control is available (the “class-C” baggage compartment
is heated by the passenger cabin air flowing into it), the Baggage
Ventilation System provides an adequate environment for carrying live
animals in the compartment.
The Baggage Ventilation System is composed of two ambient check
valves and a baggage compartment fan.
Whenever the recirculation fan is off, the forward check valve prevents
reverse flow into the passenger cabin and the two check valves
prevent smoke or fire extinguishing agent penetration into the
passenger cabin or into the rear electronic compartment, (refer to
Section 2-7 - Fire Protection).
