The second or variable mode of operation permits planners and operators to vary the characteristics of the supplied platforms (within limits) and also vary the one-way transit distance from the staging airfield to the location of the slick, the average pass length of the oil slick, and the utilization time (UT), the time available for the platform to operate
in a day. In this mode, user-defined platforms can be added, edited, and deleted. A time adjustment for mobilization and cascading of platforms from out of area to the staging site can also be made.
