To calculate distance, time and ESA for a flight plan:
1. From the CAL 1 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, along with
the total distance and the minimum
enroute safe altitude for the flight
plan (figure 4-73).
4. Once you have selected the
desired flight plan, move the cursor
to the groundspeed field on line 4.
5. Select your estimated ground-
speed for the trip. As you change
it, the estimated time en route
(ETE) calculation will be updated
(figure 4-74).
4.5.2. THE CALCULATOR 2 (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 Pilot’s Operating
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.
