3.2 „True“ Wind
•
Definition refer to
chapter
Wind velocity (WV):
The wind velocity is indicated as an instantaneous value on the three-digit red LED display.
Units of measurement are m/s, km/h, kn and Beaufort. A red illuminated status LED shows
the selected unit of measurement.
The
wind velocity
is calculated on the basis of the relative wind and the ship’s movement.
Wind direction (WD):
A circular arrangement of 72 rectangular LED’s indicates the wind direction and its variation.
The wind direction is calculated on the basis of the relative wind and the ship’s movement.
Depending on the setting (refer to
chapters
and
chapter
for representation on the indicator), the direction of the True Wind either corresponds to
geographic North or to the direction of the ship’s bow.
Since the scale 0...180° for starboard and port side is printed, 180° ...360°, instead of
0...180°, must be assumed with the „True Wind“ indication for the port side.
•
The wind direction within the range 0...180° is indicated by means of a green LED.
•
The wind direction within the range 180...360° is indicated by means of a red LED.
•
The wind direction at 0°, 360° and 180° is indicated by means of a yellow LED.
•
The variation is shown by means of an LED band, in “green” within the range 0...180°
and in “red” within the range 180°...360°, in which case the LED that marks the wind
direction, in the LED band, lights up yellow.
•
Operating mode „True Wind“ is indicated by a status LED (True).
Attention:
A wind direction scale of 0…360° must be assumed in the event of
indication „True“.
