What happens if you go above the certified altitude?

Could a turbocharged piston even get high enough and go fast enough to get into the coffin corner?

Here is how to do it wrong...

That was a great article. I think that makes it pretty clear how rapidly performance drops off with altitude. If a Jet would have that much trouble holding altitude at that little above its normal operating altitude, I could only imagine what it would be like in a piston. Thanks!

I was going to mention the Pinnacle CRJ crash in 2004 but I think those guys only just reached the service ceiling before the performance dropped off and they had an aerodynamic stall and double flare-out.

I'm not an aeronautical engineer, but I suppose it's possible to get into trouble with a piston turbo airplane.
That's part of the problem... Go over the published max and you are a test pilot.

I wonder how the performance of the Piaggio is at its ceiling. Any "coffin corner" challenges?

 

[LDJones]

At high altitude stall speed can increase to meet max Mach. As the speeds converge it can give a very narrow speed range which to fly. That's the "corner".

I guess I needed to add a smiley, too.

Lol!!! Should've known you were too bright for that mistake!!
