2. Enter the aircraft’s true airspeed
by using the right inner knob
(figure 4-91). If the CAL 6 page
was previously used to calculate
true airspeed, it will already be
displayed.
3. Use the right outer knob to move
the cursor to the Hdg field, and
then use the right inner knob to
enter the aircraft’s heading (figure
4-92). The headwind or tailwind
and the wind direction and speed
are now displayed. The wind direction is relative to true North.
NOTE: The wind calculations are only correct when you have
entered the correct aircraft heading and true airspeed. Make sure to
re-enter new values if you change airspeed or heading.
NOTE: If the KLN89(B) is interfaced with a compatible source of
heading information, line 2 automatically displays the aircraft’s head-
ing. Heading is then automatically input and used in the wind
calculation displayed on the CAL 7 page. If the KLN89(B) is inter-
faced with a compatible air data system in addition to a compatible
heading source, the Other 11 (OTH 11) page displays wind informa-
tion directly.
4.5.8. THE CALCULATOR 8 (CAL 8) PAGE
The CAL 8 page is used to determine the times of sunrise and sunset
for any waypoint in the published or user data base.
To calculate sunrise/sunset times:
1. Select the CAL 8 page
(figure 4-93). The first time the
CAL 8 page is selected after the
KLN89(B) is turned on, the way-
point identifier defaults to the
current destination, the date defaults to the current date, and the
time zone defaults to the system time zone. Each of these three
items may, however, be changed. The sunrise and sunset are
displayed at the bottom of the page.
NOTE: The time zone initially displayed is the system time zone.
This is the same as the one on the SET 2 page. Note that the time
zone displayed may not be appropriate for the waypoint shown. For
