The only constant acceleration is the acceleration of gravity. A "leaky
integrator" with a 2 or 3 second Tau should work fine.



How so? the plane doesn't know if it's right side up or not.
You can do a barrel roll, or loop and always keep "down" through the
bottom of the seat.

That's a good question. I have run every other scenario over in my mind, and
it looks to me that the proposed system should deal with them under any
normal circumstances.

However, I had not considered a constant acceleration "barrel roll" while
maintaining the same heading.

How to sense that???
My original idea had included an electronic "Gyroscpe"

I had eliminated it when I discovered how hard the iMEMS ADXRS300

are to get, but I may have to put it back.

A homemade version is available.
