The KLN 89B GPS (Global Positioning System) is a three-
dimensional precision navigation system based on 24 earth orbiting
satellites. Receiver Autonomous Integrity Monitoring (RAIM) is a
function that every IFR-certified GPS receiver must continuously
perform to assure position accuracy. RAIM is available when 5 or
more of these satellites are in view, or 4 satellites are in view and a
barometrically corrected altitude input from the airplane's altimeter
is made. Annunciation is provided if there are not enough satellites
in view to assure positic:n integrity.
Operational guidance for the KLN 89B GPS Navigation System is
provided with the Bendix/King KLN 89B Pilot's Guide (supplied with
the airplane). This Pilot's Guide should be thoroughly studied and
VFR operations conducted so that you are totally familiar with the
GPS system of navigation before actually using this equipment in
I FR conditions.
