        1.  Lay out symbols by using strips of fabric or parachutes, pieces of wood, stones, or any available material.
        2.  Provide as much color contrast as possible between material used for symbols and background against which symbols are exposed.
        3.  Symbols should be at least 10 feet high or larger. Care should be taken to lay out symbols exactly as shown.
        4.  In addition to using symbols, every effort is to be made to attract attention by means of radio, flares, smoke, or other available means.
        5.  On snow covered ground, signals can be made by dragging, shoveling or tramping. Depressed areas forming symbols will
           appear black from the air.
        6. Pilot should acknowledge message by rocking wings from side to side.
