Airbus Cargo smoke : the philosophy
ok here's an issue that's bothering me arising from lack of consensus in the training : On an A320 family if you have a cargo smoke alert and you activate the extinguishing agent , the smoke warning will remain because the smoke is now trapped in what becomes a tight-seal compartment and the extinguishing agent itself is perceived as 'smoke' by the detectors .
By this fact many instructors conclude that a fire cannot reignite . You have an extinguishing agent which 'inhibits' the potency of oxygen to sustain combustion within that tight-seal space . With this thought you really do not need to act immediately for the Red LAND ASAP . You can examine the possibility of continuing to your destination if its relatively close and occasionally have a flight attendant checking the floor above the affected compartment for any unusual heat .
I have my ideas and thoughts on this issue which I will not mention now .
I would like to know your approach and thoughts on this issue and more importantly how does your training department sees it
