#2 OBS, what would you do?
Our #2 OBS is a KI-201C. Our avionics guy rescued it when it turned
out to be inop after we bought the plane, by soldering in a $10 capacitor or some such, and it worked flawlessly for about 5 yrs. Now a 10 degree change on the OBS only produces half deflection. This time same avionics guy can't find anything to fix (so far). Our set-up is #1 KX-170B w/ glideslope receiver, KI-206 (I think) #2 MX-170B, KI-201C Apollo 2001 GPS (IFR approach certified), Mid-continent CDI We're contemplating our options. Replace #2 with a KI-214 (integral GS receiver) so we have two LOC/GS? with a KI-209a/external GS receiver so we have 2 LOC/GS but also something which might be capable of VNAV at a later date? Leave out the #2 OBS altogether and fill the hole with an electric horizen gyro? We can identify intersections and back up the loc with the GPS...course it's less precise... Other alternatives we haven't considered yet... Thoughts? What would y'all do? Cheers, Sydney |

My #1 LOC/GS is currently the KI-214... Purchased outright, used, from
Eastern Avionics.. Driving it with the MX-170B, which is a slide in for the KX-170... Working just fine for two years now... Denny Snowbird wrote: We're contemplating our options. Replace #2 with a KI-214 (integral GS receiver) so we have two LOC/GS? |

Ignoring used v/s new costs for the moment... Consider the VAL INS-422...
entire VOR/LOC/GS/MB radio in one small hole in the panel... No moving parts... Should last a long time.. My #2 VOR/LOC/GS is an MX-300A and it has the LED needles built into the face of the radio... Not legal for approaches I suspect, but it is dead nuts on when compared to the KI-214... A great comfort to me when I get carried away and shoot ILS approaches in actual... I agree on the utility of the 2nd GS... I had a GS fail during an approach - in actual - a few years back... The &*^%($# piece of lethal crap failed with the GS needle centered and no warning flag... Only when I noted that my VSI showed that I was flattening out at ~300 fpm and there was not a corresponding GS needle deviation, did I begin to question things (up to that instant I thought I was an ATP)... The ceiling was 100 feet below legal for a localizer approach, but knowing the airport very well, and knowing that I was descending into a flat area, free of obstructions, I opted to keep the localizer needle centered and and the VSI on 380 fpm as called for on the approach plate... I broke out on center line, and on glide slope according to the VASI... The MX-300A was ordered the very next day while I was shopping for a complete #2 nav/com radio package and I stumbled across it whilest talking to Eastern Avionics owner... It slid into an existing tray on the panel saving me installation cost... A $35 used splitter for the GS antenna and I was in business.... Denny "Snowbird" wrote in message om... wrote in message ...

Denny, How did you handle the install? Did you do it yourself, or have it done? Approx. hours or cost? We had our 201C repaired when we bought the plane. It held up fine for 5 yrs but is now fritzing again. 2 yrs isn't long on the GA timescale :\ Cheers, Sydney |

Actually, we're considering that. Our avionics guy never heard of it. It's pricier up front but it's *possible* that the installation costs would even out. Anyone here w/ experience want to comment? My #2 VOR/LOC/GS is an MX-300A and it has the LED needles built into the face of the radio... Not legal for approaches I suspect Why do you say that? Why shouldn't it be legal for approaches? I agree on the utility of the 2nd GS... I had a GS fail during an approach - in actual - a few years back... The &*^%($# piece of lethal crap failed with the GS needle centered and no warning flag... Yeah, that's happened to a couple of people we know, leading to our reluctance to just substitute an electric horizon gyro. Cheers, Sydney |
