(c) CHARLIE dddsss is the data line for the over 5-KT to 30-KT yield group.
(d) DELTA dddsss is the data line for the over 30-KT to 100-KT yield group.
(e) ECHO dddsss is the data line for the over 100-KT to 300-KT yield group.
(f) FOXTROT dddsss is the data line for the over 300-KT to 1-megaton (MT) yield group.
(3) For example. The data line of an effective downwind message reads DELTA 090025. The term DELTA
indicates that the yield of the weapon is in the over 30-KT to 100-KT yield group. The numerical data of this line represent
an effective downwind direction of 90 degrees and an effective windspeed of 25 kilometers per hour.
(4)
A data line may contain only three digits when a special case applies (para 7).

Fallout Prediction Procedure
The following procedure can be used for predicting the fallout area from a single detonation when the location of GZ, the
time of burst, and the estimated or actual yield of the weapon detonated are known.
a. Record location of GZ and time of burst on the area predictor for map scale to be used. The
