Garmin GFC 600 Autopilot Test

I flew an ILS approach to test the new Garmin GFC 600 autopilot and Garmin G500 TXi recently installed in the A36. During this approach under VFR, I wanted especially to check the coupled go-around capability of the AP. As you'll see, it's a smooth, precise autopilot.

Thanks for this. My Baron is going in the shop for its GFC600 install in about 2 weeks. I look forward to the increased capabilities.

Very nice demonstration, smooth machine and pilot. Thanks for sharing.

Very very nice Bruce. Enjoy the "new" bird.

Nice demonstration, Bruce.
To start the missed approach, did you have to push any buttons other than go-around for the autopilot? Or does that one button take care of everything? I admit I'm a bit jealous; my Century III is nowhere near that good!

Hi, Martin. In my installation, the Go-Around button switches the AP mode to PITCH and ROLL and the flight director commands a +7 pitch attitude and wings level (that value varies with aircraft type). I have to add power and retract landing gear and flaps. When flying a published MAP, I would then confirm or switch the CDI to GPS mode and select either HDG or NAV mode for lateral guidance and IAS mode for the climb to the initial MAP altitude. Some installations allow the system automatically to switch the CDI source to GPS (e.g., if you've flown an ILS, LOC, or VOR procedure). But regardless, as you climb out, you need to confirm the navigation source and select the appropriate lateral and vertical modes to continue flying the procedure. In other words, the Go-Around feature essentially starts the miss by establishing the airplane in a stable, wings-level climb attitude. You must still switch the navigator out of suspend mode, etc.

Looks good. Does the AP have yaw input, or do you still have to push the rudder yourself?

I have the yaw damper, which makes the AP a 3-axis system.
