NUMERAL PENNANTS

SUBSTITUTES

1st Substitutes

2nd Substitutes

3rd Substitutes

The use of substitutes:
The use of substitutes is to enable the same signal flag, either alphabetical flag or numeral pennant, to be repeated one or more times in the same group, in case only one set of flags is carried on board. The first substitute always repeats the uppermost signal flag of that class of flags which immediately precedes the substitute. The second substitute always repeats the second and the third substitute repeats the third signal flag, counting from the top of that class of flags which immediately precedes them. No substitute can ever be used more than once in the same group. The answering pennant when used as a decimal point is to be disregarded in determining which substitute to use.
