VOR with no Compass Rose?

[Doc Holliday]

DME/DME navigation is used by airlines now and it is one of the potential replacements for MON and the remaining VORs.

Not just airlines. Many business jets use it as well.

When I got my instrument rating in 1992, the C172 I flew had 2 VORs and an ADF. Not even DME

Same here. DME was fancy stuff only the corporate airplanes had. Without looking it up, it was probably in 1986 or 1987.

There are some that I’m aware of that were installed collocated with NDBs.

I remember some. You'd have the NDB symbol on the charge with a square over it for the DME.

Very true... I was just trying to keep to the basics that it was a thing in use today.

And I'm not looking forward to the huge expense for a really basic device crunching the numbers. But I will like to see it make it down to the smaller GA planes as a GPS backup.

Not necessarily. The charting office can and does sometimes omit the compass rose for chart clutter concerns. Note for example the Cowboy and Rangers VORs in the DFW area (CVE and FUZ).

Wrong I believe. DFW doesn't show compass rose for the simple fact DFW is class B and vfr pilot should be using a TAC chart which does show compass rose.

I remember flying a Lance in the mid 80s that had that King RNAV. Never heard it called a course line computer back then. Anyway, thought it was the greatest thing at the time. I mean, I could take a VOR and basically “move” it on top of my destination! What’s not to like about that!

Times have changed (for the better )

Loved my KNS80 Jepps even had a rnav chart you could plot rnav waypoints with.
/R baby!

Before you say he’s wrong about the reasons, go to the chart I snipped earlier in this thread, the Denver TAC.

Edit. Come to think of it, check out FUZ on the Dallas TAC and see if you can find the compass rose.

You're right no compass rose.

Wrong about what?

Compass roses are clearly not shown on all VORs. The chart drawers obviously have some discretion. There are numerous examples.

And TTT (Maverick, at DFW) has a compass rose on the DFW sectional, so I don't even know what you're getting at, that "DFW doesn't show compass roses".

 

[midlifeflyer]

You're right no compass rose.

This is from the Interagency Air Committe (FAA and DOD) charting specifications. See page 93. Notice the “when space allows” in the first sentence. It also explains the open area between the overlapping TTT and CVE rises in the Dallas TAC.

That statement isn’t necessarily true, but it highlights reason that TAC charts exist… the people who draw the sectionals (and other charts) have some discretion in omitting features due to clutter.

In the early 80's King had one that was IFR approved. KNS 80 I believe. Worked great. Most airlines have that built into the FMS as a backup if GPS goes out. And the DME portion of ILS-DME's are used too.

Personally, I think they should make a box and have this in GA aircraft. And, at our speeds, it could be done with a single DME unit, just tune different channels.

A great back up for GPS outages or jamming or spoofing.

 

[Pinecone]

Only in the planes new enough to have a TACAN receiver. I bet a few of our .mil members can tell stories about that. As one T-38 pilot at a fly-in told me, regarding the avionics, "If you can say 'unable,' you can fly this plane."

IIRC TACAN is older than VOR.

But T-38, early 60s, had TACAN. As did the A-10s, built in the 70s and 80s.
