KNS-80

Actually, I do not have a KNS-80 or other VOR/DME RNAV system in my
simulator; the KNS-80 is in my airplane. I agree with you there is no point
in a brand-new KNS-80 installation either in an airplane or in a simulator.
I am, however, debating in my mind whether to install a Garmin 430 vs. 530
later this year as part of an avionics upgrade, and I am leaning toward the
430 because it would save enough space to allow me to keep the KNS-80 and
thus maintain true DME and VOR/DME RNAV capability, two forms of navigation
which the Garmin 430/530 can only emulate based on GPS calculations.

The errors that the KNS-80 are subjected to are unquantifible at this point. If
the FAA were honest about it all, they would decertify the set for en route
operations.

Having used both the 530 and 430 I like the 530 a whole lot better. The big
display, and two separate map pages make it the clear choice if you can afford
it. Having said that, a 530 and a 430 make a great installation, too. You end
up with redundancy everywhere and use the 530 as your primary RNAV set.

Everything about the 530 is easier, including being able to see many more legs
or flight plans on FP pages 1 and 2.

Is this any worse than NDBs which have been used for quite some time?

Easier? Yes.

Is there any more function or accuracy in a 530 than a 430? No.

Cost is not the only issue -- panel space is an issue. That saves panel
space for other avionics.

Even better is crossfeeding a 530 or 430 to a handhdle 195 or 196 or 295.
A 430 crossfed to a Garmin handheld GPS is one of the best kept secrets of
avionics value... a 430 / 195 combination gives at least as much useful
information as a 530 at a dramatically reduced cost. It is actually better
than a 430/430 combination or 530/430 combination because (a) the handheld
Garmins provide an electronic HSI; and (b) the handheld Garmins serve as an
electrical backup. With crossfeed from the panel GPS to the handheld GPS, a
pilot would not even skip a beat transitioning to the portable GPS in the
event of a sudden complete electrical failure in IMC.

Could you reveal that secret of crossfeeding a 430 to a Garmin Handheld GPS
please?
I had just as backup and for user waypoint management a Garmin 196 installed at
the yoke of a 172 and would like to learn about that interesting crossfeeding. The
196 Pilot's Guide at page 96 under INTERFACE just holds a rather brief
statement on the topic:
Aviation In - the proprietary format used for connection to a Garmin
panel-mounted GPS receiver. Allows Goto or route selection on the panel
mounted GPS receiver to be automatically displayed on the GPSMAP 196. This
eliminates the need to enter the destination to both units.
And at page 100 under INTERFACING:
... The following formats are supported for connection of external devices:
... Garmin proprietary aviation input, ... .
You can download a copy of Garmin's proprietary communication protocoll from
the Help and Support section of our website at www.garmin.com
Guess, it needs some tinkering of the avionic experts to make such connection
work?

The 530 has an "arc view" map page that the 430 does not. I find it to be
the most useful moving map page and use it all the time.

Glad you said that, Mike. I feel the same way.
I always keep the arc view on my CNX80 for navigation, while (mostly)
showing the "North-Up" map on my MX20 for situational awareness.

Very interesting, Richard!
Tell me more (like how to do) as I have a 430 on the panel and a 195 on the
yoke and they are not sharing info. Do I need to go to the avionics shop and
get the connection to the 430? I don't remember any front panel controls and I
don't like going to the back. How do I tap into the 195 connector? I use
ships power to the 195 (with battery backup).

TIA

The details are in the Garmin 430/530 installation guide, which I can email
you directly if you wish as it is no longer available on the Garmin site.

You need to have your avionics shop do this (they certainly have the
installation guide); it is not particularly difficult.

As I said, the 530 is easier to use but does not contain any functionality
that the 430 does not, i.e. there is no approach or other IFR function the
530 does that the 430 cannot do.

Sort of like the difference between an HSI vs. a DG and CDI... the HSI is
easier to use but does not give any additional functionality.

Yes, it has to be connected by the avionics shop but it is a simple project
and well worth the effort.

Thanks Richard - I will visit the shop tomorrow and have them check on the
manual.
