only appear if a compatible air data system is installed with the KLN 94. If
no fuel management system is installed but there is an air data system,
the air data pages become AUX 15 and AUX 16.

DETERMINING THE STATUS OF THE GPS SIGNALS

The Auxiliary (AUX) 1 and AUX 2 pages may be viewed at any time to
determine the status of the GPS receiver and the GPS satellites being
received. This includes which satellites are being tracked, the satellites’
health, the signal strength for each of these satellites, the elevation of
each satellite above the horizon, the azimuth of each satellite referenced
to your present position, the estimated position error, and the present
GPS-derived altitude.

The GPS receiver in the KLN 94 is capable of using signals from up to
eight satellites to determine its position. A valid position may be deter-
mined using as few as four satellites alone or three satellites with a valid
electronic altitude input. However, four satellites alone or three satellites
with an altitude input do not necessarily ensure that navigation can take
place. The satellites must be positioned relative to your location such that
