7. To aid the GPS receiver in acquiring your position, it helps to
have a reasonable idea of where you are, and the Initialization
page is where you have the chance to set this initial position.
Check to see if the displayed initial position is where you actually
are. This latitude/longitude is the last known position before the
power was shut down the last time. Unless the unit has been
moved since its last use, this position should be correct. On the
right side of the screen will be the identifier of the nearest airport
in the data base, with a radial and
distance from that airport. If you
need to change the initial position
to—let’s say—John F. Kennedy
International (KJFK), move the
cursor to the WPT: field and use
the right inner knob to select a K
as the first character of the
identifier (figure 3-16). Move the
cursor to the right one character
and select a J and then right
again to select an F. The final K
should be filled in by the data
base (figure 3-17). When you
press
F
, the latitude and
longitude fields will change to
those of KJFK (figure 3-18). If
necessary, the latitude and longi-
tude may be entered manually.
8. When all information on the Initialization page is correct, move
the cursor to Ok? and press
F
to move on.
9. If the GPS is for VFR use only, the VFR page will be displayed to
notify you of this.
10. The Data Base page will now be
displayed with the cursor over
Acknowledge?. Line 1 indicates
whether an Americas, Atlantic, or
Pacific data base is being used. If
the data base is current, line 2 will
show the date when the data
base expires (figure 3-19). If, on
the other hand, the data base is
out of date, line 2 shows the date
that it expired (figure 3-20). The
KLN 89(B) will still function with
