Answer 3

Yes it is called a windsock and it is made of a very light fabric with orange and white stripes. The intention is this: A stripe represents five knots wind. If there is, say ten knots wind, you should see the cone break at about two stripes. Note that this is a very rough wind estimation and maybe not all the windsocks are designed and tested to be conform to this standard.

I don't know where you live but I live in Norway and whenever I need aeronautic supplies for my little aircraft I purchase it online from Aircraft Spruce in California. Try here:
