The glass panel does not use gyros, but the backup instruments do. 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.
Those sources aren't responsive enough. I believe the uses MEMS gyros
to provide instantaneous relative attitude information and combine them
in a Kalman filter with the other sources you mention to get long term
absolute attitude reference.
