With all of the new EFIS(Electronic flight Instrumentation Systems), has
anyone seen one that stores the flight path for replay? It looks like all of
the information is there, and this would be a tremendous help in instrument
instructing, or even "pattern review". If downloaded to a simulator on a pc,
this would be a good help answer post flight review questions. Al CFIAMI

I created an incredibly simple GPS playback mechanism. It just showed
the position on a moving sectional image and printed the speed, etc.
but I can certainly see how it would be useful.

It should be fairly simple to feed GPS data ingo FlightGear. I'll be
surprised if someone hasn't done it already but I don't recall hearing
of it.
