Some points to ponder…
In designing this panel, I would like to install two MFDs. I thought that minimally I would maintain as a backup, airspeed, and AI, compass, and altimeter.
If I go with the Enigma, they can communicate with each other, yet are independent. The only thing that would knock them both out would be a power failure, and even then, they are battery backed up.
So, considering those things, what additionally would make sense for IFR flight?
Linda, I noticed that you have an AI, AS and Altimeter? There also looks to be a vacuum gage on the left side of the panel? Do you fly your Lightning IFR?

Jim,
Another thing that I have found useful and found is recommended in a lot
of magazines like Flight Training, is after you get your plane and get used
to it, fly with an instructor and then make sure that all your instruments
are covered up (leaving some for the CFI to see, but blocked from your site)
Try to set important numbers by sight and feeling in the seat of your
pants. Get used to the sound the engine makes with power at idle and a
descent rate of 500 feet per minute. Get used to the pitch attitudes for
both 500 fpm descent and climbs. Practice full pattern approaches like
this. See what a power at idle best glide looks like and the sound the air
makes on the plane at that speed. Obviously the CFI with the instruments is
for safety. This will ensure that in any scenario you're flying the
airplane "by the numbers." It'll also make you more proficient in your
everyday flying with full instruments as well. You never know what may
happen and when you may need it. Brian W.

Jim,
I plan to fly IFR when I am very comfortable with all the Chelton system will do. Yes, the backup instruments are AI, AS, and altimeter in case of total electrical failure. The attitude indicatator is vacuum driven with a dry pump; we also have a vertical card compass which will be mounted on top of the glareshield when we install it. Because the Chelton PFD/MFD's was having problems with calibration until May 31, the EIS had to be taped on top of the panel preventing the glareshield from being installed. That will be changed out soon; the EIS will go behind the panel with blind mounting. We do not have a clock because there are timers in the Chelton system.

Jim,
One thing I forgot to mention; if you are going to fly IFR, you will also need a heated pitot tube. The 20-amp alternator is a bit of a limitation so you need to plan carefully for the electrical requirements.
Check on the Gretz heated pitot tube; it worked well for us and needs less amperage.
