6.2PLOTTING SETUP
The Plotting Setup Page is used to
configure the Plot Page and select
the types of information that will be
displayed. The first cyclic field
defines the orientation of the plot
map. The top of the plot map may be
North (North Up), the direction of
your current ground track (TRK Up),
or the direction of the active leg of a
route (DTK Up). To select the desired option, highlight this field and
press CLR. Your present position and nearby waypoints are displayed
on the plot map at all times. The second cyclic field determines what
additional information will be displayed on the plot map. You may
display the active route and a stored ground track showing where you
have been, only the active route, only the ground track, or neither.
The ground track is stored at a frequency that you can define either by:
Time “Interval”, “Resolution”, or “Distance”. Select the desired frequency
unit by highlighting this field and pressing CLR.
To store the Ground Track at selected time Intervals...
· Highlight the storage frequency field (third line) and select
“Interval” with CLR.
· Press ENT.
· Enter the time interval between stored positions starting with
hours, then minutes, then seconds. Press ENT after entering data
in each numeric field.
To store the Ground Track by Distance...
· Highlight the storage frequency field and select “Distance” with
CLR.
· Press ENT.
· Enter the distance, and press ENT. When your position moves this
distance in any direction, a new position is added to the stored
ground track. NOTE: “Distance” storage may be preferable to
“Resolution” storage if the ground track will include a large
number of turns.
