What is Track spacing?

  • Most search patterns consist of parallel tracks or sweeps covering a rectangular area.
  • The distance between adjacent tracks is called the track spacing.
  • Correction factors based on weather conditions and search object are provided in a table. Multiplying the uncorrected track spacing (su) by the appropriate weather correction factor (fw) produces the recommended track spacing.  S = su * fw .  Changes in weather, number of assisting crafts, etc., may occur, making it prudent to alter the track spacing.
  • The SMC must ensure that all searching ships and aircraft maintain safe separations from one another and accurately follow their assigned search patterns.
