NOTE
The prediction function takes a certain amount of time, depending on the route distance
and the enroute speed (i.e., 1000 nautical miles = approximately 2 minutes). The longer
the route distance, the longer the time. The slower the enroute speed, the longer the time.
Also, if there is a RAIM unavailability detected based on the associated requirement, the
prediction process will stop immediately, and display ‘NO RAIM’ as shown in Figure 3.
Figure 3. ‘NO RAIM’
4. If the entire route has RAIM availability, it will take a longer amount of time to complete, and display ‘RAIM
OK’ as shown in Figure 4.
NOTE
‘NO RAIM’ does not mean RAIM is unavailable for the entire route. It is actually the out-
come of detecting the RAIM unavailability for more than 5 minutes over the intended
flight, based on the BRNAV requirements.

2. ROUTE SETTINGS PAGE (pg. 87, Pilot’s Guide)
The GARMIN GPS 155/165 software versions 3.07 and higher incorporate a change which removes the Route Settings
Page which allowed Automatic Leg Selection and Automatic Leg Sequencing to be enabled/disabled by the pilot.
3. APPROACH SELECT PAGE (pg. 66, Pilot’s Guide)
GARMIN GPS 155/165 software (all versions):
An ‘‘unkn” (unknown) approach type is displayed on the Approach Select Page when the unit software does not know
how to display a new approach type in the database. DO NOT USE THIS APPROACH TYPE.
