Credit to Boeing

Since my post on Monday, which caused quite a stir on some social media discussions, a couple of people have pointed out to me that the Boeing 787 Dreamliner has a ‘no-bleed’ system for providing cabin air, which eliminates the most obvious risk of a ‘fume event’. This was something I was aware of, but perhaps I could have put it in the piece. In 2007, in evidence to the House of Lords in the UK, the company stated:

“The Boeing 787 will have a no-bleed architecture for the outside air supply to the cabin. This architecture eliminates the risk of engine oil decomposition products from being introduced in the cabin supply air in the rare event of a failed engine compressor seal. In addition, this architecture improves fuel efficiency, thus reducing fuel burn and associated engine emissions.”

To the best of my knowledge, it has not referred to this aspect of the no-bleed architecture in a public statement since.

  1. Boeing have a 10 year lead over Airbus who continue to use bleed air.

    Boeing will come clean one day soon in a competitive world – absolutely no question, at all.

    After all, Boeing ‘worked out that crew and passengers were being poisoned’ way back in 1999, when Aerotoxic Syndrome was first defined.

    1999 – The same year that the Dreamliner B.787 was conceived.

    Coincidence?

    No.
