You gonna get lost. lulz
Have a back up plan huh? Map?

That's according to a flight advisory just issued by the FAA, which warns pilots that their GPS signal "may be unreliable or unavailable" due to "GPS tests" that the Department of Defense will be conducting between January 20th and February 22nd.

I have a two stage backup plan. Stage one, have map. Stage two, don't let wife read map.
Hell, I can't drive upside down anyway.

I'm betting there's a back-up plan with people on the runways guiding the way with laser pointers.....

There is nothing strange about this. DoD needs the system for that time. So for that time period you backup everything with other navigational systems. Thhe Dod needs the system. And when the Dod wants something they GET IT!!

Of course they get it if they need it. The DoD owns the system :)

People have been flying on instruments without GPS for a very long time. Airways and VORs work very well. Though I am told they are not replacing NDB units as they go down, the old ADF system is still available over much of the country. Doan need no steeenking GPS.

Yeah, 3 VOR's and you are just as accurate as GPS. 2, and your damned close. 1 + Dead Reckoning puts you rather close.

I know the alert said it could be inaccurate, but I'm wondering how? You can't take part of the system down, so I'm at a loss as to what is going on, since it needs to be damned accurate while used in military operations (Which are ongoing)...

Never flown with 3 VOR heads; never even seen an a/c with three. Plenty of hardware with 2, some plus the GPS. Never flew with a GPS, though. My experience was limited to VOR, and it was one or none; and the only one I was used to was a blue/yellow type. ;)

Hello.

The newer glass cockpits allow for up to 5 VOR fixes at the same time.
This is done with one receiver that can scan and a plotting function.
Since the scanning is done quickly there is no lag whatsoever.
And of course this is a VORTAC, so you get the DME as well.

A VORTAC is a facility on the ground, not something in the aircraft.
