Flight Safety,
Here are some concerns:
- If the air separation module fails in a certain way, youŽll pump HOT bleed air (with normal oxygen content!) into the tanks to be inerted - not a good idea IŽd say.
- Secondly, the FAA tech centre didnŽt say anything about how the ASM will be affected by environmental influences (such as dirt, engine oil etc...), especially in the long run.
- Thirdly, has anyone considered back flow of fuel into the comparatively hot ASM...!? If it can happen, it will happen!
What also worries me is that none of the proposals from the FAA or Boeing shows any monitoring device whether the system really works or not.
Last but not least: An inerted tank is a safety hazard for maintenance!
Why not spending all this money to avoid CFITs for example?
Cheers,
J.V.
