Basically u will get an alternate routing, depicted by the symbol shown on my previous post. For example, check Dupont (DQO) VOR just south of philly.

They are printed because they are just "segments" of a specific V route that r out of service.....maybe tempo. maybe for good....maybe just MX on the station...or conflicting signals.....who knows!:eek:

thank you
 

thanks all for responding.

If it's two jagged edges on the break in the line, it does not mean that the airway is "unuseable" - if this were so, they'd remove! What it means is that
there is a gap in VOR (or other radionavigation aid) reception- at one point, you'll lose the VOR you're flying away from without having picked up the one you're flying to.

What do you do? Stay above the MEA, not the MRA or OROCA or MOROCA and maintain the heading which was keeping you on course until you pick up positive navigational coverage (meaning the needle is alive and indicating correctly) from the next navaid.

In fact, the website has several good PDFs regarding IFR and VFR charts.
