ANNEX M ; , PERATIONS ORDER NO. 2PART .1 - WB-29 RAD/SAFE CODE FOR CLOUD TRACKING OPERATIONS The code for in-flight reporting of radiation will be used in con junction with the five digit groups normally devoted to AFOAT-1 reporting. Position, time and altitude will be as normally reported on weather reconnaissance flights, The first group of the five digits group will be used to encode the radiation observations, Readings and general observetions are to be coded in sequence and if conformance with the code below. Should the first five digit group not adequately describe the report, suc- cessive five-digit groups shovld be used. To indicate such amplification, the first digit of the first five digit group should be coded accordingly. The numbers indicated for coding the desired information below are exam ples only, Formal random code numbers will be assigned by CJTF SEVEN prior to the first shot for successive three-hour periods starting at H~hour and terminating at H plus 48 hours. Copies of formal code numbers will be furnished to the Weather Central and the operating agency.
