Will there be another “gyroscopic” instrument apart from the two G5s? If not that might be risky
There will still be a turn coordinator, and the dual G5 installation has a reversionary mode if one of them fails. The G5s also have 4-hour backup batteries of their own.

Garmin, EI , Avidyne & Trio ?
I have found Garmin to be trustworthy and honest. I have no experience with EI or Trio.
I was talking about Avidyne, from whom I bought something four years ago and they still haven’t delivered; they’ve actually stopped discussing it altogether, so I am left with a dog, on which I am going to have to spend money cutting across to Garmin.
I just can’t imagine why anyone wants to buy from them.
I have received a fantastic product from Avidyne. The DFC90 autopilot is awesome and everything works as advertised.
I hear good things about the IFD440/540/550.
I have an IFD540, IFD440, & AXP340 xpdr (incl ADS-B Out) and am very happy with them.

Don’t you need a stand by attitude indicator for IFR? As I understand Aspen does require a standby AI even if two independent Aspens are installed, including dual antennas, sensors etc.

No, only ASI, VSI and altimeter. The HSI in a dual G5 installation may be switched into AI mode if necessary.
These Garmin v. Avidyne debates will always carry on. There are many variables e.g.
A search on e.g.
garmin AND avidyne
digs out a lot of past threads.
I would think that in the NAV/COM marketplace both companies today offer similar products, and you pick the one you like more. Make sure it supports the various interfaces to other stuff e.g. your specific model of fuel totaliser etc. For example is the EI FP-5L fuel computer known to work in a specific installation? I have seen stuff in Garmin installation manuals which actually does not work (e.g. the GTX330-KLN94 connection).
I think that Avidyne actually release great products when they release them but they are seriously capital constrained. The IFD is a nice piece of equipment. As was the DFC90.
My problem is the Garmin ecosystem is far more extensive, better supported and lilely to have greater innovation in the future. So if you just want the IFD it should be fine so long as you dont expect to be able to ever interface it to anything.
But if we are going to do analogies, i would see Avidyne as OS/2 to Garmin’s Windows.

I’m afraid it’s just the opposite: on its interfaces to other devices, IFD440 pretends to be a GNS430, a bit like the OS/2 subsystem in Windows 2000

Which is odd given that Avidyne Entegra and System 9 runs Windows NT

Which hardware does Garmin’s GTN (the analogy to the Avidyne IFD) interface with that Avidyne does not interface with and is not made by Garmin?
