Do I have to explain what it means when you add the non prefix to any word, including this?
Afraid so, since you've worked your way into a corner. Could you give an example of 'non-navigable airspace' ? Does it include uncontrolled airspace, is it off an airway...,? Since it doesn't seem to exist in any text or regulation I've ever read, I'd be interested in where it can be found and how it's defined so I know if I'm ever in it.
C'mon, this is a toy airplane site. Only us nerds read this stuff.Just admit you're making it up.
Not making it up. Non-navigable airspace is simply that which is not navigable airspace, simple english. I gave you the US code that defines navigable airspace. It is not used for aircraft control, but is used for towers and other structures because you have little or no restrictions when erecting in non navigable airspace.
As far as not seeing any reference to navigable airspace, its right there in the title of part 77 "SAFE, EFFICIENT USE, AND PRESERVATION OF THE NAVIGABLE AIRSPACE ."
