    Posted: 01 Oct 2023 at 11:41pm
Friends - 

Can anyone tell me how to do a 30-day VOR check with my IFD540 and a Garmin G5? I've done one in the past, but for whatever reason (brain fart?) I couldn't do it today.

I'm trying to do an airborne VOR check and compare the IFD to the CDI on my KX155.

Thanks.

There are several ways:

1) Pick a VOR radial (180 for example) and fly the airplane on the radial to the station.  Put the IFD in VLOC mode by rotating the upper right knob, center the CDI and the same on the KX155.

2), Set your bearing pointer on the G5 to the VOR and note where it points.  Compare to the KX155.

That's what I thought I was doing yesterday, but no joy. I'm beginning to think there was a problem with the VOR we were using.

Did you tune and identify the VOR?  Did the IFD VOR datablock show the VOR, Bearing, Distance?  Did you read the NOTAMS from your preflight briefing to see if it was out of service?

Yes. Yes. Yes.

And yet, both the G5 attached to the Avidyne and the CDI attached to the KX155 seemed to be acting "funky," which has me thinking that there was something going on with the VOR. Or maybe just extreme "operator error." We're flying again on Thursday and will check with (hopefully) a different VOR. Unfortunately, at least around here (SoCal), it seems the VORs are out of service more often than in service.

What VOR did you try using?  So many VORs have been either decommissioned or "temporarily" out of service

RZS. It wasn't on the NOTAM list, but both the IFD and the KX155 CDI were acting weird. Since both were acting up at the same time, I'm wondering if there was some sort of glitch with RZS at the time I was trying to do the VOR check.

is there a VOT near your area .. just thinking that if testing in the air isn’t working , try something else.

There's another nearby VOR that, at this moment, is in service. We're going to try that next. If that isn't workable, we're going to have to look at other options.

The VOT at KCMA uses VTU VOR. A lot of times VTU is OTS as well.

You are correct the VOR doesn't have any NOTAMs against it and should be up.  Make sure you are within the usable service area of the VOR

  1. VOR UNUSBL 066-076 BYD 40 NM BLW 9300 FT; 066-076 BYD 48 NM; 077-081 BYD 40 NM; 082-097 BYD 40 NM BLW 9000 FT; 082-097 BYD 51 NM; 134-140 BYD 40 NM; 140-178 BYD 27 NM; 318-065 BYD 40 NM.
I'm not familiar with the area (and I didn't look at the chart) but anything outside of the above you may not get a signal

Aloha, my friend!

The VTU VOR is out of service more often than the CMA and other VORs. I have this feeling that in the not-to-distant future, they might decommission it.

Very possible that we fell into one of unusable below or beyond parameters. Thanks for posting this info!

To close this out, I went up yesterday and did the VOR check with a different (nearby) VOR, and it worked perfectly. Both needles were within 1* of each other. So, though it was never in a NOTAM, I think the previous VOR was malfunctioning at the time I tried to do the test originally.

Thanks, everyone, for your suggestions.
