1.5 Selecting Apparent or True Wind Angle,
Wind Speed
You can show wind angle and wind speed in apparent or true wind. The
apparent wind is the actual flow of air acting upon a sail, or the wind as
it appears to the sailor. True wind is the wind seen by a stationary ob-
server in velocity and direction.
WIth a wind angle or wind speed indication displayed, press the APP/
TRUE key to change the wind angle or wind speed to apparent and true
alternately. A beep sounds after the change is completed. (Wind angle
and wind speed displays are mutually changed.) True wind requires boat
speed input. If there is no speed input three dashes appear.
