comment Extracting acceleration vector from rotated aircraft
You are welcome. I think it's fine if you leave it there. This is just a geometry problem.

Yes you may say that. It's really only a matter of reference point.

comment What is the longest distance that can be jumped after swinging from a rope?
thank you very much for the answer. The paper provided some very useful analysis. Now question(2) is kind of trivial(purely mathematical problem). But I believe question 1 is unanswered, and remained interesting.
