I plan my flight on my handheld GPS, then lay it out on a sectional, while
flying, I track myself on the map and make sure I am whereI think I am. The map
has more detail then the handheld gps I use (garmin 295), so if I have a
problem I know where I am and whats under me.
I do this when flying over clouds and cant see the ground, I look at the map
to see whats under the layer.

Do you people with GPS units (either panel mounted or portable) use only
them when you fly, or do you plan the same route on a map as well and plot
your position in flight, for backup in case the unit looses pickup? I've
recently seen the SR-22 panel and some Lancair models and it got me
wondering whether aside from all these hi-tech gadgets people still use the
good old roadmap.
