5. Select your estimated ground-
speed for the trip. As you change
it, the estimated time en route
(ETE) calculation will be updated
(figure 5-7).
5.1.2. THE CALCULATOR (CAL) 2 PAGE
The CAL 2 page is for calculating fuel requirements for a trip. To use
these pages, you need to have a good idea what the typical fuel flow
rate for your aircraft is. This information can often be found for given
cruise power settings in a "performance" section of the operational
handbook for the aircraft. The units for fuel are not specified on this
page, but the units of time are always hours. This means that you
can use gallons per hour, pounds per hour, kilograms per hour, etc.
Like with the CAL 1 page, the fuel calculations can be done from
waypoint to waypoint (including present position), or for one of your
flight plans.
To calculate fuel requirements from waypoint to waypoint:
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 Wpt.
Press
E
to toggle if this is not the case.
3. Turn the right outer knob
clockwise to move the cursor to
the "from" waypoint in the upper
right corner of the screen
(figure 5-8).
4. Enter the desired identifier for the "from" waypoint and press
F
. The waypoint page for the identifier you just entered will be
displayed. If it is the correct one, press
F
again.
NOTE: On either of the two waypoint fields on this page, you can
select your present position. To do this, press
E
while the cursor is
on the desired waypoint field
(figure 5-9). The results will only be
displayed when your KLX 135 is
receiving a valid position, or if you
happen to be in the Take Home
mode (see
section 5.5, "Using the
Take-home Mode").
