The avionics smoke detection system consists of the following:
A smoke detector, and smoke detection control unit.
Will an APU fire test shut down the APU?
No.
Illumination of the GEN 1 LINE SMOKE light indicates:
Smoke has been detected in the avionics compartment ventilation duct.
Cargo smoke warning is activated when smoke is detected in one cavity by:
Both smoke detectors.
One smoke detector when the other one is inoperative.
In the event an aft cargo compartment smoke detector detects smoke:
The crew must depress the appropriate DISCH switch.
How many halon fire extinguishing cylinders are there per engine?
Each engine has two fire extinguishers.
