Actually not - that message is in reference to the minimum airspeed for the autopilot to maintain, not the stall speed.

Here is what the SkyView HDX Pilots User Guide has to say about it.

Quote:

When the Autopilot is engaged, SkyView uses the indicator shown in the following figure to
denote that the aircraft has reached its maximum or minimum airspeed limits as configured
when the Autopilot was set up.

When either of these indications is displayed, the autopilot will not pull or push on the pitch
axis in a way that would exceed these limits. Instead, the Autopilot will actively pitch the
aircraft up or down to prevent exceeding the maximum airspeed or dropping below the
minimum airspeed. This may prevent the Autopilot from reaching its programmed targets, and
can even cause the Autopilot to maneuver contrary to its programmed targets in order to
remain within the allowed airspeed limits.
It says nothing about this indication still appearing after the Autopilot has been disengaged. Nor does it mention that in some screen configurations it will obscure the ball. Now since disengaging the A/P leaves the FD on, it makes sense that this is not tied to the A/P but rather to the FD.

Most of my flights include some time on autopilot and I get this indication often, typically as I come in over the runway. The ball isn't particularly necessary then so it doesn't bother me. My recent encounter with this with slow flight maneuvering is concerning though.

I'll send something to Dynon as well. In the meanwhile, I'll be sure to turn off the FD during slow flight.

As mentioned already, the latest software update has moved the slip/skid ball location so this is not a problem. You don't need to bring it to Dynon's attention, you just need to upgrade to the latest software version. It's a problem that has already been solved.

No, that is not actually the case with the HDX. I am running the latest software version (15.4.7) and this is where I am getting the problem. Might be true for the older Skyviews but not the HDX.

The problem exists with the current software. That is the software I have loaded

Sorry - got ahead of myself there - I am running a Beta test version of software 16 on my HDX, and the slip/skid ball is moved on that software. 15.4.7 probably still has it in place.

That's encouraging news. While I doubt you can say, do you have any idea when Dynon intends to release the update?

I can't say - because I don't know, sorry. There are a few beta testers for various reasons that get to try out new hardware/software and report back on how it works - but none of us get to know when the final release is. If field testing should uncover some particularly nasty bug it might take quite a while to correct it - though in this case the software version I'm running has been in beta for quite some time without upgrades, so I'm hoping that means we are close to full release.
