Commercial Supersonic ?
(OP)
seeing news about supersonic developments.
how does this sit with aviation becoming carbon neutral ?
in this future where we have to watch our energy expenditures, is this an appropriate way to go ?

RE: Commercial Supersonic ?
> the overcrowding of all airports is not getting better, so tying up a jetway time slot for a tiny number of passengers will be expensive, and the only plausible way that could work is if the terminal is completely remoted from the general flow of passenger traffic
> ditto the takeoff/landing slots -- this is more intractable, since the noise is likely to force such planes into a daylight slot, which need to be reserved for planes that carry more passengers
> the inevitability of a higher cost will limit the clientele to the rich and/or profligate -- not conducive to the general public accepting getting bumped to let such a plane into the flight schedule of the local airport

I don't know that we have that ability to prevent someone from building one, based on CO2 alone, short of some rather drastic political changes.

RE: Commercial Supersonic ?
Actually, I think we have plenty of opportunity to "kill" this. Easy to make a rule "if supersonic then no CO2 emissions". Now of course they'd just go shopping for an approval (if not the US, then maybe Russia?) … which'd only create another windmill (to tilt at).

If such a policy is designed and implemented correctly, then the overall effect can be net eco-positive.
RE: Commercial Supersonic ?
I know NASA and others have worked on aerospikes etc that are supposed to make things quieter, but I hadn't heard of any major breakthroughs that would completely eliminate the boom.
RE: Commercial Supersonic ?
NASA investigates the 'FaINT' side of sonic booms - phys.org
RE: Commercial Supersonic ?
That just leaves:
> noise and air pollution
> deconfliction of landing slots -- if this results in more private jets flying into already crowded airports
> deconfliction with other aircraft -- something that's going twice as fast as you results in less time to avoid collisions
> deconfliction in air traffic control -- shorter timelines means more potential conflicts, more stress, etc.
> possible need to run SSAs at a different set of altitudes to minimize interactions with slower aircraft

RE: Commercial Supersonic ?
I have to think that even if at ground level an aircraft doing mach 1.5 at 35,000 ft isn't audible that if that same aircraft is flying anywhere near a typical A320 or 737 commercial flight that it's going to scare the pants off of everyone inside. I've looked out the window on flights and seen aircraft heading the opposite direction within probably half a mile or so of the aircraft I was on. If that other plane was going supersonic I have to think you'd feel it. What kind of additional airspace requirements would be necessary?
