PlaneSmart question: Whats the standard & maximum (non-emergency) cabin air refresh rates (times replaced per hour) for the 7e7 at 30,000 feet, and how does this compare with other aircraft in the ANZ fleet, in particular the 747 and 737?
I don't know the answer to that question. Seems a silly question to ask though. Seems like I might have got your back up because you were dead set on the idea that the NZ
7E7 program is a joke...
Concern over passenger health is silly? Nz1 is "at a level in the company to KNOW what is truth and what is crap. I don't say things that are untrue."
The question was directed to Nz1 because he is a senior manager in ANZ, with access to information, including commercially sensitive stuff. ANZ
is one of only 2 airlines with firm orders for the 7e7, and as a firm customer, is working very closely with B to determine specifications.
I've raised similar question on other threads.
Reason for my question is in theory cabin air refresh rates in aircraft using bleedless engines will be restricted to electrical power that can be generated to heat incoming air, whereas non-bleedless engines use bleed air thru a heat exchanger.
Pumping stale air through air conditioners does not make it good air. Most passengers have experienced breathing probs at some time or another on a flight. I always hope the people at the pointy end are getting good stuff.
