Advanced GPS Operation

Chapter 4

Turn the right outer knob
clockwise to move the cursor to
the "from" waypoint in the upper
right corner of the screen (figure
4-75).

Enter the desired identifier for the

"from" waypoint and press

. The waypoint page for the iden-

tifier you just entered will be displayed. If it is the correct one,
press

again.

NOTE: On either of the two waypoint
fields on this page, you can select
your present position. To do this,
press

while the cursor is on the

desired waypoint field (figure 4-76).
The results will only be displayed
when your KLN 89(B) is receiving a

valid position, or if you happen to be in the Take Home mode (see
section 4.11, "Using the Take-home Mode").

Move the cursor to the
groundspeed field on line 2.

Select your estimated ground-
speed for the trip (figure 4-77).

With the cursor over the "to"
waypoint, enter the desired identi-
fier (figure 4-78) and press

Move the cursor to the fuel flow
rate field and use the right inner
knob to select the desired value
(figure 4-79). Remember that this
can be in any units you desire (as
long as it's per hour), but the
same fuel units must carry
through the calculations.

Move the cursor to the fuel
reserve requirement field and
enter the desired value. As you
do, watch the calculation of fuel
required on line 4 change (figure
4-80).
