I have several hundred hours behind (a) Dual G5s, (b) GI 275s, and (C) Aspen PFD1000.
They are all great units - the G5s are the simplest but with great visibility and affordability.
The Aspen is best for screen size, and the speed and screen clarity of the new MAX units, especially with synthetic vision, is really nice.
The GI275 is a truly incredible unit - very powerful with amazing screen quality and lots of flexibility and redundancy. A great ecosystem for expansion.
Future considerations:
I know the GI275s do NOT work with the DFC90 autopilot, which is my opinion is an incredible upgrade to the STEC. I donât believe the G5 will either. Both the G5 and GI275 work with the Garmin GFC500 autopilot out of the gate, which is about $15-25k installed depending on options.
I believe the GI275s do work with the STEC.
I donât believe the G5s will work with non-Garmin GPS/Comms, though I may be mistaken.
The Aspen works with the DFC90 but last I checked did require some sort of unlock fee.
If a DFC90 is in your future the only Garmin PFD that works with it in a Cirrus is a G500TXi.
A lot of intersecting decisions⌠important to decide where youâre taking the planeâs avionics in the future as you choose a replacement PFD.
On the topic of autopilots, I prefer the Garmin GFC500 to the DFC90, but only marginally. And a lot of that is due to Avidynes refusal to provide ongoing warranty coverage and the flat fee repair if your DFC90 goes down.
I have been in this debate myself⌠currently leaning toward a future of 3 GI275s including their EIS and a GFC500 autopilot to replace the DFC90, with a large panel mounted iPad to replace the MFDâŚ
