Not sure where the autopilot is on the priority list but I'd sure like to see VNAV high on that list. I find the heading modes, especially GPSS, to be really good and wish I could couple glideslopes as well. I know it's on the list. Can you give us an estimate of when it might happen? RV-8A, SV 1000 and GNS 430W. Hurry, I'm startin' to get old. Jack L.
