BendixKing KLN 94 - Pilots Guide - Manual (Page 157)

WARNING: Do not use the GPS-derived altitude for navigation. Due
to many factors, the GPS altitude may be 300 feet or more in error,
which is unacceptable for navigation.
Lines 4 and 5 of the AUX 1 page display the KLN 94’s estimated position
error. The KLN 94’s position error depends upon such factors as the
number of satellites being received, the strength of the GPS signals, and
the geometry of the satellites presently being used for navigation.
Figures 5-54, 5-55 and 5-56 show a
representative example of a set of
AUX 2 pages. There will be three
AUX 2 pages if more than six satel-
lites are being received as in this
example.
The following information is dis-
played for each satellite on the
AUX 2 pages:
• The specific GPS satellites or
“space vehicles” (SV) being
received are displayed in the
left column. Each satellite has
its own identification number.
A * symbol to the right of the
satellite number indicates this
particular satellite is not
presently being tracked by the
receiver.
NOTE: At some times, you may desire to deselect certain satellites if you
know them to be inaccurate, so that they are not used to determine the
GPS position. Should a satellite be inaccurate, it could cause a RAIM fail-
ure, rendering the system unusable
for primary IFR navigation. To dese-
lect a specific satellite, turn on the
cursor (
B) and move it over the
desired SV number (figure 5-57).
Turn the right inner knob to deselect
(or reselect) the desired satellite.
• The satellite’s “health” (Hlt) is indicated to the right of the satellite
number. The health of the satellite can be described as Gd for
Good, Wk for Weak, and Bd for Bad. Ds indicates the satellite was
deselected by the pilot. Fd indicates the receiver detected a fault
and excluded that satellite.
