Rev 5 Jul/2004 KGP 560/860 Pilot's Guide
The KGP 560/860 GA-EGPWS may also be installed in aircraft that do
not require FAA approved TAWS systems, and may be utilized with an
optional set of alerting and warning parameters that are designed espe-
cially for smaller piston aircraft and their normal flight characteristics.
The FAA has now designated these operational TAWS requirements,
under TSO C151b as the Class C curves. These “optional alerting and
warning parameters”, now Class C operations, are set into the computer
via the Configuration Module during installation, and require no pilot
interaction.
