Advanced GPS Operation
Chapter 4
To calculate fuel requirements for a flight plan:
1. From the CAL 2 page, turn on the cursor (
B
). It will appear
over a cyclic field that either displays Wpt (waypoint to waypoint)
or Fpl (flight plan).
2. For this type of calculation, the cyclic field should display Fpl.
Press
E to toggle if this is not the case.
3. Turn the right outer knob
clockwise to place the cursor
over the flight plan number. As
you cycle through the flight plans,
the first and last waypoints of
each flight plan will be displayed
(figure 4-81).
4. Once you have selected the desired flight plan, move the cursor
to the groundspeed field on line 2.
5. Select your estimated groundspeed for the trip.
6. Move the cursor to the fuel flow rate field and use the right inner
knob to select the desired value. 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.
7. 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 4-82).
4.5.3. THE CALCULATOR 3 (CAL 3) PAGE
The CAL 3 page may be used to set a timed alarm. Instances where
you might want to use it include as a reminder to switch between left
and right fuel tanks or maybe just to remind you to eat lunch! Line 1
of the CAL 3 page shows the current time in the system time zone.
The alarm may be set by either of two methods: entering the time of
day you wish the alarm to activate, or the time interval from present
time (i.e. twenty minutes from now). Line 4 displays the elapsed time
since the KLN89(B) was turned on.
