BULK CARGO COMPARTMENT
Applicable to:
VENTILATION
Air from the cabin goes via the inlet isolation valve to the bulk cargo compartment, and is driven by
an extraction fan. Air is controlled by the outlet isolation valve, goes to the bilge, then through the
aft outflow valve.
NORMAL OPERATION
The cargo ventilation controller controls the inlet and outlet isolation valves and the extraction
fan. The ventilation system operates when the isolation valves are open. To open the isolation
valves, set the BULK ISOL VALVE pushbutton to ON.
The controller closes the isolation valves and stops the extract fan, when :
The flight crew sets the BULK ISOL VALVE pushbutton to OFF, or‐
The bulk cargo smoke detection unit detects smoke.‐
The outlet valve closes and the extract fan stops, when the flight crew sets the DITCHING
pushbutton to ON. In case of overheat, the extract fan stops and the OVHT COND FANS
RESET FAULT light, on the maintenance panel comes on.

HEATING
Bulk cargo compartment heating is performed by an electrical fan heater. Air from the cabin, driven
by the electrical fan, goes into the compartment through a heating element. The temperature
demand is selected from the cockpit.
NORMAL OPERATION
Provided the cargo door is closed, the heater operates when the temperature sensors indicate
that the compartment air temperature is less than the selected one.
