IFR Chart question
So my roommate got asked a question by his instructor. He didn't know the answer so he's supposed to look it up. I figure APCforums had a wealth of knowledge we can use.
Q:
On IFR en-route charts there are mileage break points. Sometimes instead of these there are jagged lines. The kinds that are used on graphs so the markers don't have to start at zero. What are these points called and what is their purpose?

Without seeing it, I believe that you're speaking of a "Change over Point" where you switch from one navaid to another while enroute between VORs on the airway.
The introduction section of the Jepp Charts, or the legend on the actual NOS (or whatever they call them now) should have the answer.

It's definitely an unusable route segment. It's defined on the gov't charts...dunno if Jepps has it, never used theirs. Not quite sure of the meaning though, never given any thought to that since I got my IR...and honestly, never seen it since. Doesn't really sound logical...why print a segment that isn't usable.
