6.2.14. APPROACH PROBLEMS
Very rarely there will be a problem with the integrity of the GPS system
while you are conducting non-precision approaches with the KLN 94. In
some cases the KLN 94 will determine that there will not be sufficient
integrity monitoring for the leg between the FAF and the MAP, or RAIM is
not currently available. In these cases the KLN 94 will not go into the
approach active mode and will present the following message:
*RAIM Not Available
APR Mode Inhibited
Predict RAIM on AUX 3
In these cases you will not be able to finish the approach because there is
insufficient integrity monitoring. The AUX 3 (Auxiliary 3) page provides a
means for you to predict when RAIM will be available if the KLN 94 is con-
figured for IFR approach operation.
