This is all very timely for me. I started my instrument training in Sept and it was put on hold due to my 300xl dying. I'm in the middle of an extensive rework of the panel with an ifd440 becoming my ifr GPS. It's a long slog.
In the process of thinking about equipment I recalled several local folks who fly down to Southern California reasonably regularly talking about remarkably frequent GPS outages, where there is essentially no GPS signal for significant amounts of time. The theory is that there is GPS signal jamming going on at one of several military installations in the region and one or more of those facilities is actually developing and testing jamming technology. The point being that my sense of warm and fuzzy surrounding the reliability of GPS got a bit of a reality check and the importance of ground based navigation was reinforced.
I'm still working on the panel installation and rat's nest of wiring, but I think I am firmly in the "putting it back together" phase, rather than the "taking it apart" phase!
