Garmin 530 VOR Approach Using GPS or VLOC

[Rich]

I have a Garmin 530 and a KAP 140 autopilot in my 182. I was
practicing VOR approaches with the CDI on the 530 set to GPS. I
noticed that the autopilot would warn that it was about to disengage
when I reached the FAF. It does this consistently. If I put the CDI in
VLOC, the autopilot would not try to disengage.

I tried a VOR approach at another airport with the CDI set to GPS and
at the FAF a message came up on the 530 warning me to set the CDI to
VLOC.

I know that on an ILS approach the 530 will warn you to set the CDI to
VLOC but I never read anywhere that it does the same thing on a VOR
approach.

I called Garmin and they suggested I put the CDI in VLOC but they
didn't tell me that it had to be in VLOC for the approach. They only
said the 530 could be sending a signal to the autopilot to disengage
is the CDI is not set to VLOC.

Anybody have any ideas on this?

Regards,

Richard

You will get that message on any approach that is not authorized for
GPS. That includes ILS, LOC, VOR, and NDB. If it can be flown with the
GPS only you will not get that message.

If this were a GPS overlay approach, I would not expect that
performance.

On the other hand, if this is a VOR approach without an overlay, then
why would you not want to put the CDI into VOR mode? You need to have
at least one VOR receiver tuned to the approach, and the moving map on
the Garmin 530 will give you GPS backup no mater what the CDI button
selects.

I have a 430 and its connected to my HSI and to my auto pilot (piper auto
pilot)
my auto pilot will fly the plane untill it hits the ground if I let it. At
the MAP I hit "susp" and then the auto pilot will fly the missed. All I do
is set my HSI to what ever the GPS says and it flies the line. Never
disconnects. You may want to take it to your avionics shop, see if it has
a setting they can change to keep it from doing that.
