Chapter 6 Approaches and DP/STARs
To perform a RAIM prediction on the AUX 3 page three pieces of informa-
tion are needed. The first is the location that the prediction will be for and
the second is the time for the prediction.
The destination waypoint will, by default, be the missed approach point of
an approach loaded in the flight plan. If there is no approach in the flight
plan, then the default waypoint is the last waypoint in the active flight plan.
Of course it is possible for you to enter any waypoint in this field.
The time used for the RAIM prediction will be the current ETA to the desti-
nation airport or the MAP. This time is automatically updated by the
KLN 94 so there is usually no need to enter a value. If you are making a
RAIM calculation for planning purposes, it is also possible to enter a time
in this field. An important point about this time is that the time used for
RAIM prediction is always in the future and limited to 24 hours from the
present time. For example, if the time is now 19:30 and the time entered
for the ETA is 18:30, then the prediction will be made for the next day not
one hour ago.
The third piece of information is to deselect a satellite (SV) if you know
from some official source that it is unusable. A satellite entered on the
AUX 3 page is ONLY deselected for RAIM prediction.
To perform a manual RAIM calculation:
1. Turn the left outer and inner knobs to select the AUX 3 page.
2. Press B. The cursor will be over the RAIM @Dest field.
3. If the default waypoint is not the one desired, enter the desired way-
point identifier by using the inner and outer knobs just like you do for
any other waypoint entry.
4. Once the desired waypoint iden-
tifier is entered (figure 6-54),
press F. Press F again to
approve the waypoint page.
5. The cursor will now be over the ETA field. Use the inner knob to enter
the desired hour. Note that the system time zone is displayed next to
the ETA field. Use the outer knob to move the cursor over the minutes
field. Use the inner and outer knobs to select tens of minutes and sin-
gle minutes as required. When the desired time is selected press F.
The RAIM calculations will start.
NOTE: If you wish to deselect a satellite from the RAIM calculation, move
the cursor to the Deselect SV field and turn the right inner knob to select
the satellite (SV) number. Unless you know otherwise, leave this field as
NONE.
