Cabin air quality - Ozone or what?
This has to be one of the most enduring subjects in the public eye, airlines accused of recycling unhealthy bug infested, high CO2 air, yet nothing seems to be done about it.
Why is this ? On first reflection this appears very odd as there is a limitles supply of fresh air outside and all you need to do is scoop it in and heat it up to a cosy temperature. Easy.
What's the real reason then? Is it that at 40,000ft poisonous levels of Ozone are so high that scooping in outside air is a no no? Or does replenishing clean engine bleed air increase fuel burn or represent a power penalty i.e. real issues for the operators unlike passenge welfare?
Will current generation, 787 380, airplanes be better?
If you haven't got a cold or flu the chances are you will by the end of your next flight hopefully nothing worse
