  faa.tg.dynamicDensity.math.sector.SectorParametersCalculation

public class SectorParametersCalculation
extends java.lang.Object

This object represent calculation of sector area, sector major heading and sector aspect ratio. (Metron Algorithm) 1) Sector Area = 2 * area of sector bounding rectangle / Aspect Ratio 2) Aspect Ratio = d1 / min(d2, 10.0) where C = center of sector's bounding rectangle d1 = distance from C to furthest sector vertex d2 = distance from C to nearest sector boundary 3) Major Heading = heading C to V1(-180 to 180 degrees) where C = center of sector's bounding rectangle V1 = subsector vertex furthest from C X and Y in nautical miles. See the source SectorParametersCalculation.java
