Also, think about where your screens are in your plane. My RV-14 has a G5 on the left, then a 10” PFD, then an avionics stack (just a GTN 650 and GMC 507), and then a 10” MFD on the copilot side. I barely even use the MFD because it’s so far over there.
The way to get more utility from the MFD is to operate the MFD in split screen mode, with the knob-selectable content on the left (inboard) side and the one of three screen choices on the outboard side. This brings the MFD closer, and is how I do it on my RV-9A.
If you look at any of the full screen displays, almost all the information content is in the center half and the outside quarter on each side adds little extra information.
On my installation, the standard setup is:
** On the left screen, left to right: engine instruments, flight instruments, selectable "MFD" information.
** On the right screen, starting from the aircraft center (left side): "MFD", flight instruments, engine instruments
Even if nobody ever flies the plane from the right side, split screen is useful because it brings the highest information content closer.
I had an iPad but sold it for lack of use... my flight plans are almost always GPS direct, so uploading from an iPad has little value.
Garmin has under-sold the usability of the two-screen system, a lot... how sad.
