Don't shoot the messanger...that's what he said.

Thought never occurred to me. Since this animal goes back to the late 60s I’m sure there are lots of “interesting” details.

I know this because, I have completed full stalls in the type, long ago....and not something I desire to repeat

Now that would be a fascinating read! If you ever care to write up that experience I would love to read it (names & dates deleted to protect the guilty). Feel free to PM me if you care to pass on that little experience.

Mad (Flt) Scientist:

But flight slats-in could be all the way up to Vmo. If autodeploy was capable of initiating from zero slat, you'd have to consider both the case of the accelerated/high-g stall near Vmo and the failure cases causing inadvertent autodeploy at Vmo. The hazard involved would perhaps bias against auto-deploy from clean, especially if the characteristics were already reasonable without it.

............. Fascinating analysis - thank you.
