Back-up CDI
The G500 and G600 STCs produced by Lees require a back-up CDI to be installed if the aircraft is certifed for any thing other than VFR.
Lees are currently writing the EASA STCs for the G500 in the R112/114, B55/58 Barron, 23/35/36 Bonanza, and changing all of their current G600 STCs (PA28, 32, 23) to include G500 and SVT. PA34 and PA44 should also follow by April.
The Nav 2 data from either a GNS430W or SL30, can be sent to a dedicated CDI as well as the G500. The SL30 uses RS232 to communicate with the G500, so it's analogue 6-wire resolver and deviation/flag output is available for a mechanical CDI. A GNS430W has digital interface (429) to G500 and can use the un-switched VOR/LOC analogue output to the standby CDI.
