MODULE DETERMINATION CHART The chart in Figure 1-5 is used to determine the number of screen modules required to cover your equipment.  Table 1-1 will also aid you in making your decision. To determine the number of screen modules, calculate "A" and "B".  Find "A" value (screen width, in feet) on the Module Determination Chart and go across to "B" value (screen length, in feet).  Where "A" and "B" intersect on the chart will give you the number of screen modules required. Formulas A=2h + w + 5ft and B=2h + L + 5ft have been devised to determine the number of screen modules required.  Do calculations in feet. h = height of object, in feet + 2 feet (for overhead clearance) L = length of object, in feet w = width of object, in feet A = width of screen in feet B = length of screen in feet That part of the object which falls within the slope of about 50° can be disregarded in determining "L" or "w".  A slope of about 50° gives maximum effectiveness in camouflage. Example: A=2 (8 ft + 2 ft) + 10 ft + 5 ft; B=2(8 ft + 2 ft) + 25 ft + 5 ft; A=35, B=50.  The nearest size of screen according to the chart is a two module configuration.  Keep in mind that the formulas and charts are guides and the selection of screens and the combinations must be tailored to the individual situation.
