larrynimmo Posted April 12, 2018 Report Posted April 12, 2018 Recently I had brand new Garmin GTN650 installed, and basically the installer has said that it is not directly compatible with the Century41 autopilot. To get it to work, I have to take the course bearing from the GTN, and line up the yellow line on the HSI (like you would do with a Vor) is this right? Prior to the GTN, I had a KLN94, and it would talk directly with the Century41.... I would appreciate that anyone having the two products would comment.... Quote
kortopates Posted April 12, 2018 Report Posted April 12, 2018 Not sure I understand you. If you are saying that you need to set the HSI OBS to the DTK-Desired Track then that is normal when you do not have an auto-slewing HSI - which I would expect with your Century and this don't mean they're not talking to each other, just the HSI can't autoslew. But also keep in mind the OBS on the HSI does not have to set to the proper DTK to get proper right/left CDI indications, since just like on an ILS it doesn't matter where you put the OBS, but you still want to dial in the proper course/radial for your own improved situational awareness. A more important test would be to put the GTN 650 into OBS mode on the GPS and make sure the GPS senses what ever your HSI CDI OBS is dialed too. i.e. if you have the CDI OBS set to 150 degree and you push the OBS button on the GPS while in GPS mode, the DTK on the GPS should now be on 150 degree or very close to it and as you turn the OBS knob on the HSI CDI to change the radial/course the GTN DTK should be updating to match whatever you twisted the radial too . (On the 650 you need to be on the Default Nav page to do all this) 1 Quote

Did you install a GPSS? The C41 uses the ADI for steering. Without some sort of GPSS the GTN will not drive the A/P. Quote
