Interesting thread.

What about onbthe simple side of things.

I have teak grips with the PTT on the top.

If I were to add an autopilot button, should it go in the trigger position, panel, should the PTT be moved and the AP button installed on top?

Suggestions please.

PTT on trigger, AP on top.

Why?

The right stick will retain the PTT on top.

Because I find it easier to just "squeeze" my finger to activate PTT than to press my thumb down. It's just more comfortable for me.

I never fly from the right, so that's not really of much concern for me (plus, there's only one button on that stick anyway, whereas the pilot's stick has quite a few functions...trim, A/P, smoke, PTT).

Default TOGA GMC vs GTN

Michael,

did you find out whether it's enough to wire the TOGA input into the GMC507 or does the GTN need a dedicated input?

Thanks,

They both need TOGA:
On the G3X, TOGA takes the autopilot to pre-programmed pitch up and wings level;
On the GTN, TOGA activates the missed approach procedure for guidance;
The pilot still has to reconnect the autopilot to the GTN on a missed approach.

On my RV-9A with a fixed pitch prop, if I'm slowed to final approach speed and go to full throttle and TOGA, the plane gets as slow as the autopilot programming will let it. This means that an autopilot go around at minimums would be interesting. However, following the lead of a jet test pilot friends, I try to avoid flying where ceilings are less than a thousand, just in case the engine poops out, so that means that I don't ever plan to fly an approach to minimums in IMC. The key phrase here is that I don't *plan* to, but I still need to know how to do it reliably. I go through the TOGA drill on every approach, and I always engage the autopilot on every takeoff, just for practice, even on a VFR flight. If I had a constant speed on the RV-9A and better acceleration, TOGA acceleration might not be as much of a factor.

Default TOGA GMC507

As the GMC507 is connected via CAN Bus to G3X, no dedicated/discrete input is needed for the G3X. The question is if the G3X can trigger the Missed Approach Proc on the GTN remotely..
