GDC31
Anyone have any experience of this device? It's a roll steer unit that will couple many GPS units to many autopilots, getting over the Garmin/STEC requirements for this technology. I'm thinking of putting one in my Saratoga, and wondered if anyone had fitted one to their birds, or if they'd used one....... |

I don't but I looked at their website. It looks like a converter box that
takes in RS232 data and outputs Arinc 429 and analog composite roll steering. I know that the 430 and 530 output Arinc 429 and the Garmin GAD42 will convert this to analog composite roll steering. I think that you still need an autopilot that will accept roll steering inputs. My experience is that you want as few manufacturers as possible in your avionics stack. I have a 530 with a GAD42 providing analog roll steering input to the autopilot in the MU-2. The GAD42 will also reformat a bunch of other data. Mike MU-2 "Mike Granby" wrote in message oups.com...

The GDC31 will convert serial RS-232/422 GPS data into one of two things. One, it will create an analog heading bug signal that can drive the autopilot in heading mode using GPS course and course deviation. It works like what STEC calls a GPSS converter. There is a panel mounted switch that allows you to switch back and forth between the real heading bug and the faked heading bug made by the GDC31. Two, it can convert that serial data into Arinc 429 roll steering messages for autopilots that can use it. This is for cases where you have an older GPS that has only serial output and doesn't have a 429 output. I've seen it work in somebody else's plane, seems to do a good job. |
