Display of GPS approach type

[330drvr]

While giving an IPC on a certified Garmin equiped aircraft, I noticed a great feature. On the CDI for a GPS approach it showed on the EFIS the type of appoach, ie LPV, or LP +V, or LNAV, whatever. I know my GPS of course has this information but having it right on the EFIS during the approach was very nice. Could we add that?

The type of approach is not transferred to the EFIS by the GPS. There is no standard data field in the RS232 or ARINC 429 protocols to transfer this information. Garmin has their own secret protocols to transfer this data to their equipment.

Interesting, thanks for the reply.
