Re: Max height of passenger seats

thanks for the replies.

I've been told the individual airframers have max seat heights (measured from the floor) of between 42 and 45 inches. However I've measured seat backs up to 47 inches myself, so I wonder if such limits are recommendations, rather than anything legally binding.

Max height of passenger seats

Through a work thing, I've been looking at a few of the more adventurous seat concepts in detail, from crazy designs like the AirGo project (now dumbed-down a great deal) to downright cruel ones like the Skyrider saddle seat. A few of these seats are quite a bit taller than current designs, and I wa...

Re: Cygnus - small supersonic jet concept

What would happen if the device used to move the wing into place were to malfunction mid-flight? How would that affect the speed and range? I feel like that would be a risky device to have for a flight that far. I guess the same applies to any long-haul aircraft, since an air brake, thrust reverse ...

Re: Cygnus - small supersonic jet concept

I thought sonic booms were really only an issue when transitioning into supersonic flight. Once there... no more issues with ground noise. Now, height of the transition does affect how much (if any) ground noise you get. That's a common misconception. I'm not an expert, but a supersonic (let's say,...

Re: Cygnus - small supersonic jet concept

And SST can still fly over land despite with speed limit ... Strictly-speaking, you should be able to fly up to mach 1.2 (ish) without a noticeable sonic boom as long as you fly high enough. Though other factors like atmospheric conditions and flight manoeuvres can concentrate shockwaves, even in s...

Re: Cygnus - small supersonic jet concept

re: swing-wings - in Concorde's supersonic cruise, the Olympus 593 and variable inlet combination was (IIRC) actually one of the most efficient machines ever built. Concorde's poor fuel economy was largely due to costs associated with the delta wing design - namely having to accelerate with afterbur...

Re: Cygnus - small supersonic jet concept

I'm guessing a small airliner for 30+ passengers is easy enough to reconfigure as a 8 - 12 person business jet

What are people's thoughts on this new design concept?
