Sorry Bob, I wasn't very clear when I wrote of the W&B that is carried in the plane. I just have the scenarios of light, forward, heavy and aft covered in the W&B that I have in the plane. I've also found that the forward part of the envelope (full fuel, including tip tanks and just me at 160lbs) to have unexpected characteristics. I found that is was a bad idea to land full flaps because with the full flaps pitching moment I barely had enough elevator to keep the nose off and the nose came down at a higher speed. Wouldn't have been good on an unimproved strip.

Great to hear that you are getting so close to completing your Phase 1 testing!

So essentially, load your airplane into the worst possible configuration you can see being possible, fly it there in Phase I (assuming it's still flyable) and that defines your usable Phase II envelope.

.... and that's exactly why we test the corners in Phase I - good to know these things...

Good idea but why not use beer?
