En-Route
I flew my long solo XC a few days ago and made prodigious use of VORs en route.

Sometimes my flying is just wandering towards interesting views and not direct from A to B.
Congrats on getting close to your PPL...
Thanks. And like Hawk just said a couple posts back- GPS sort of feels like cheating on a test.
Yes. Frequently.
Two reasons:
(1) There are still a lot of rental airplanes with no GPS. Even IFR. I took up a /A Warrior just last month IFR.
(2) Especially for IFR, GPS disruptions and outages do occur, sometimes over large areas. While regs do not require a terrestrial alternative with WAAS, it's a good idea to have it, and be proficient in its use. GPS signals are quite vulnerable to interference, and there are apparent military exercises in exploiting this going on.
And you'll occasionally see claims that VORs are "going away." There is nothing like that on the horizon. Some redundancy is being reduced, and that's about it.

Long live the VOR!
I dug into the MON information that Bob suggested, and it was pretty interesting. I found this, similar to what you were saying:
- GPS is a very weak signal and therefore vulnerable to unintentional or intentional interference

- The GPS signal is almost a billion times weaker than other navigation signals (DMEs, VORs, ILS, etc)
I always kind of assumed that the only instance in which the whole GPS system would go down would be some sort of apocalypse. Apparently that isn't the case. Long live the VOR!
Sometimes out here in the west it does. Occasionally there are NOTAMed tests making GPS unreliable for a radius of hundreds of miles, depending on altitude. When I'm skirting the edges of the R-areas in western Nevada and the GPS starts acting squirrelly, I like to have the VOR needles confirm that I'm safely outside the hot airspace.If the entire GPS system ever dies

The CDI head that was installed with my 430W has been nothing but dead weight. And an aggravation. The 430 always flashes up a message "turn VOR to xxx degrees" after entering a new heading.
This thread should have been a poll.
I almost exclusively use GPS but I don't always fly direct. I program in waypoints over various things I want to go buy. When I get bored Ill tune a VOR and determine where I am on the charts.
Interesting tidbit I learned when talking with a Delta mainliner: the MD-88/90 and B717s don't have GPSs installed (except for a few of the very latest MadDogs they received).
Here you go!I have thought for a long time now that the avionics manufactures should build their boxes to be able to do RNAV calculations using the VORs and display the same magenta line on a moving map display just like GPS. Sort of a simulated, somewhat less accurate GPS using ground based inputs instead of satellites.
