Peter and Jim,
Thanks for the input. I've got 100+ hours on my EFIS also and have really enjoyed it. Trutrak is going to upgrade it from an APIII to an APIV for me for a really good price. That will add GPSS steering and the capability to fly coupled approaches.
Jim, I plan to add a heated pitot to the AOA system. Do you think that will suffice? The handheld radio on the left has nav capability and glideslope for backup. I have it connected to a Bob Archer antenna in the left wingtip. I'm planing to add a VAL Nav2000 above the 400W with a separate glideslope indicator where the magnetic compass is.
