AIS publications such as AIP's use arc's to define lateral airspace borders. This element is especially designed to allow you to define exactly the same airspace in a map.

draw an arc with center position <point1> and given radius from <point2> to <point3> in a clockwise direction using the amount of segments given.

Three <point> elements are required.

Example

Brussels CTR: 504434N 0043404E - an arc of circle, 10 NM radius, centered on 505405N 0042904E and traced clockwise to 505203N 0044435E - 504434N 0043404E.

  <arc radius="10" segments="45" clockwise="true">
      <point lat="N0505405" lon="E0042904"/>
      <point lat="N0505203" lon="E0044435"/>
      <point lat="N0504434" lon="E0043404"/>
