| Subject: | Glideslope upgrade options |
My strategy, not a recommendation or advise: invest low in gs technology,
upgrade when I get serious about ifr to 430Waas or to newer gs equipment that
the Garmin users are throwing away. I bought a freshly overhauled KNS 80
(vor/loc/gs/dme) with tray and backplate for $600. I've seen others advertised
that claimed to be working good for half that. Big, ugly, heavy, but no
subscription required. I can only shudder to think what repair costs might
be.....
Other than the cdi wiring, rest of wiring for KNS80 (or 81 if the external
dme is not used) is not complicated: antenna(s), power, ground, lights, nav
audio, dme audio.
KNS 80/81 and Garmins need a cdi with resolver, KI 206. Collins 350/351,
there are some ARC indicators that work but its a big secret to me. I was also
interested in the TKM led cdi, but can't get confirmation that it will work
with the Garmin/King stuff. I also read that the TERRA cdi will work with
King/Garmin, but that the light bar technology goes out of whack (a step motor
for lighting the bars instead of direct led lighting like the TKM?). Or use a
new MidContinent/Garmin cdi with the internal annunciator lights and all , I
don't see them for sale used, 206 I see for $900, collins a little less.
TKM new is $600 I think.
Query: can you legally install a KNS81 (even cheaper) in a certified
aircraft, simply don't hook up anything to the dme input, placard the unit as
"DME
permanently inop". Are there any electrical reasons not to do so, or do I
need to put a jumper in, or what? I have talked to pilots who have used the
KNS81 with the dme out for repairs, would there be a long term degradation?
So, at upgrade time to 430 I will keep my KI206: re-pin one end of cdi
harness for Garmin; add gps antenna; move vor/loc/gs antenna to Garmin; re-pin
ends for power, ground, nav audio wires, comm wires; and change mounting can
over. Donate KNS80? Good luck, Skip
Other than the cdi harness, the electricity part of the install is simpler
than the mounting/antenna/
