4.2.5.3 Wind Rose Options
WeatherView includes wind roses for wind data indication. The following elements are
typically included:
• Arrow indicates 2
‑
minute average wind direction.
• Colored pegs on the circle perimeter indicate the 10
‑
minute wind direction variation.
Typically, the variation is always displayed. Optionally, it is possible to display the
variation only when the ICAO rules apply (ICAO Annex 3).
• Runway graphic indicates the runway direction, either from north or tower view.
• Optionally, wind values may also be displayed in the middle of the windrose.
Depending on user needs the wind direction can be displayed either based on magnetic
or true north.
Depending on your system configuration, the runway graphic inside the windrose can
indicate the runway direction either in the north view or in the tower view:
