Greg_D Posted August 17 Report Posted August 17 Do the subject avionics play well together? What functions on the 275 are not available with this setup? Specifically, does the flight director work? What about altitude pre-select? Glide slope/glide path coupling?
slowflyin Posted August 17 Report Posted August 17 I have a Pair of GI275s with a King KFC 150. Works well! My alt preselect functions are not available on the 275 but everything else works great. I’m not familiar with the KAP but the KFC has a flight director and it works well with the GI275s. No regrets.
Jake@BevanAviation Posted August 18 Report Posted August 18 GI-275 ADAHRS+AP units work just fine with the KAP and KFC 150 series autopilots. The KAP will not have flight bars and there is no alt preselect functions with a GI-275. You must follow the alignment procedure outlined in the GI-275 IM when interfacing with the King autopilot. We have done this interface multiple times on various airframes and no issues. Make sure whoever is the installing shop knows this interface, has the KTS158 or has built the breakout harness in the GI-275 IM before, and has done the alignment to the flight computer. 1

How do you preselect altitude? Still using the KAS297? What GPS are you using to drive everything?

Yes, the KAS297. I also enter the desired altitude into the GI275 as it offer altitude call outs, alerts, TOD, BOD and what I call the banana on the map to show my both. My navigator is a GTN750. Works great but definitely no Alt. Select or ROC via the GI275. 1
