- 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.
