Frank: Good list to start with. I would add anything that's already on a bus as those are normally cheap and easy parameters. Angles of pitch and roll are always helpful, too.

Now that you've opened the can of worms, engineers and accident investigators never have enough data, but designers never have enough memory ... and nobody has enough money or can afford the added weight and complexity. This is sooooooo way cool.

Bottom line:
You are so on track with this one. Fantastic idea. I look forward to learning more in the new thread.
