Not sure what Scott B reason is but mine would be #2 allows you to quickly
tell what attitude instrument is no good.  With only two, you have to guess,
with three it's a democracy.

Scott,

thanks for your input.  Can you say why #2 over #1?

A wrinkle in the equation is that the ILS CDI can not be used by the GPS.
They don't speak the same language.  I really hate this widespread use of
proprietary buss's  in the aviation world.  If desktop computers did that,
they would still cost $10,000,  which come to think about it, thats what
aviation computers cost! 

thanks, Scott D

For IFR ops, I think I would vote for Possibility #2.
Put the CDI on an A:B switch for Nav 1<>Nav #2 (unless the Dynon EFIS can 
display one of the Nav's).

I'm going to be installing two Dynon instruments. One an EFIS an the other 
an EMS(Engine Monitor System).  I have 8 3.125 instruments in an extended 
6 pack configuration.  The standard 6 pack plus two CDI's to the right, 
one for the GPS the other for the VOR/ILS.  Two rows of 4 instruments. 
Because of the size of the Dynon units the easiest place to install them 
is where the CDI units are.
 
So I now have 8 holes and 10 instruments.  2 have to go. I'm looking for 
input as to which two instruments to ditch and why you think so...
 
First some info on the existing instruments.
1.) The AI & DG are integral to my auto pilot so for now they must stay. 
This also gives me redundancy for gyro instruments, one set vacuum the 
other electric.
2.) The GPS course will be displayed on the Dynon when the EFIS or EMS is 
in HSI mode, but they don't have a course indicator when it is in AI 
mode.. Not sure when they expect to get that added.
3.) The VOR/ILS can not be displayed on the Dynon, incompatible interface.
 
I have attached an image of what the panel looks like and possible layouts 
I have come up with. I welcome any comments..
 
thanks, Scott
