YEOMAN Sport 37
When the RADAR input is set to the YEOMAN, the ‘lollipop’ on
the RADAR will track the position of the YEOMAN mouse on
the chart, see Section 10.2 below. An electronic compass
input is needed for the RADAR to enable this. Note that
Course Over the Ground input from a GPS cannot be used in
the place of a compass.
10.2 RADAR plotting
Set the YEOMAN into Navigation Mode, see Section 7, and
then display range/bearing using the / key and then:
• Press the * key once to send a snap-shot of the Mouse
position to the RADAR. Note that this does not
automatically update. Further presses of the * key are
needed to update new range and bearing to the RADAR.
• Alternatively, hold the * key down for five beeps and
then release it. The YEOMAN then streams
range/bearing data to the RADAR continuously from the
Mouse position wherever it is moved. There may be a
slight delay in the response of the RADAR ‘lollipop’,
which varies with RADAR model and manufacturer.
As soon as range/bearing display is changed, then output to
the RADAR ceases. A short period later the RADAR ‘lollipop’
display will then disappear and ‘no data’ may be flashed
(dependent on RADAR used).
RADAR plotting will also function in a similar way from DR
mode, Section 9.
The YEOMAN RADAR plotting system does nothing more nor
less than replicate a manual plot, with the exception of being
easier, quicker and less prone to manual plotting error. The
sources of error are thus the same and fall into the following
categories:
