Looks like the AV-30c is getting the HSI STC. It's been available for experimental for a few months. Maybe they are launching it for Oshkosh?


Select option for "STC". Shows "not available". Only $100 more than experimental.

This will allow me to replace my CDI from my KX-155 with an HSI. I'm still stuck with my vacuum system for a while until I replace the autopilot. But at least this puts me on a path for a gradual upgrade. AV-30 has direct support for Aerocruz autopilot.

Not quite. The AV-HSI is an ARINC429/RS232 adapter, a digital interface. The KX-155 is analog.

Thanks for pointing that out. I missed that one. I guess it's a candidate for replacing my CDI that is connected to my Avidyne IFD.

Maybe not.
Per installation manual:
The AV-Link-E, AV-APA, AV-HSI, and Transponder are not powered by the AV-30-E internal battery. Wi-Fi traffic dataUAV-1004233-001, AV-30-E Pilot’s Guide Rev J Page 18provided to the MFD mode, autopilot interface, navigation, and transponder functions will be unavailable during a power loss.

I suppose as long as the alternator is turning, or the battery still has a charge, it would be okay. but with total ship power failure this could be a problem if in IFR. On the other hand, the GPS unit would be offline anyway. So it might not matter.

Further reading: Trig TX56 and Garmin SL30 serial adapter are supported as well as some other non ARINC receivers. The receiver needs to have a serial port. KX-155 not supported because it is fully analog.

I see a Trig TX56 in my future.
 
I installed an Av20s recently & have discovered it is exceedingly sensitive to the slope of the panel. Since it is behind the panel, shimming is a challenge (surface mount has been remedied by 3D printing a mount, I hear). Don’t know if this applies to the av30s. Just a heads up.

The AV30's are fairly solid. Many will say the Garmin is better blah blah. Yes, of course it is. But I've used the AV-30 in actual IMC several times now. It does the job (assuming you have the magnetometer installed).

I'm surprised the GNC255/215 didn't make the list. Oversight? Or firmware incompatibility?

It would use the serial port -- not the ARINC protocol. In the POH it explains the limitations. The HSI will work but not the leg, waypoint and other GPS features.

The GNC255/215 are not GPS.

I guess perhaps they're lumped into "other navigators" along with the IFD550.
