Nope. The hatch marks are painted on the same face that the big numbers
are painted on. They are stationary. The disk that supports the 10,000
ft pointer, and has the letters ALT painted on it, has a "window" cut out
of it, that will slowly cover up the hatchings as elevation increases. At
10,000 ft, about 75% of the hatch marks are obscured. I think this is to
aid in visually identifying that you have reached the tens of thousands of
ft. elevation.


Nope? You just said it tells you when you're over 10,000 MSL.


I think what he meant was, "it" (the stripped area) doesn't rotate, the
window you see it through rotates with the 10000's pointer.
