er 5. 00916 Ships' starting point. The starting position of the ships will be dependentupon the meteorological variables that establish the fallout area and its rate of propagation; however, in all cases the position will be as close to bomb zero as possible. 6. Time in fallout. The course was arranged so as to permit the ships to experience fall-out for as long a period as possible; in no case will the ships encounter fallout while not on the straight line run. 7, Wind speed. Courses were determined for wind speeds varying from 5 to 25 knots in 5-knot increments, so that the proper course can be selected when this variable is known, 1.4 Based on the above deecksions, graphical layouts were constructec in order to indicate to the control aircraft the information needed. From these layouts and with the necessary meteorological information, the ships' starting location, starting time, steaming speed, steaming time, and bearing can be determined. By observation of the layouts, it can be seen that the area around the shot points has been broken up into segments and plots made within each segment to scale the required information. The segment to be used in any case will depend on the forecast of the downwind direction of the fallout, while the course information to be used within this segment will be dictated by the forecast of the effective rate of propagation of the fallout area. ST. UGUIS FRC Very close liaison between the control personnel and the Task Force Weather Central will be maintained so that up-to-the-minute changes in the forecast of the direction and effective rate of propagation of the fallout area can be utilized in positioning the vessels. It is anticipated that minor shifts required because of revised weather forecasts can be compensated for up to shot time, aaa SYS
