The
Garmin 1000 gets pitch information by detecting changes in the vertical
component of the Earth's magnetic field and by cross referencing that with
information from the GPS. It does the same with roll information. It sounds
complicated, but it really is just a fancy compass.

It sounds like an upgrade of the Garmin 196!

all the best -- Dan Ford
