Brent (and all else involved at Chelton/SFS),
Congratulations on getting those boxes TSO'd! I'm sure it's a real
challenge navigating through all those hoops. Good thing you have a good
nav display :-).

Since you've been involved in the process, could you describe what this
implies for those who might want to install such a system in a certified
airplane? Is a TSO sufficient to install these boxes, or does one
further need an STC (or some other acronym) for each airframe type? Any
plans that can be shared regarding the retrofit market?

Thanks!
