? ‘aux oye OPERATIONS ORDER NO, 5-54 PART 1 - WB-29.RAD/SAFE CODE FOR CLOUD TRACKING OPERATIONS The code for in-flight reporting of radiation will be used in con junction withthe five digit groups normally deyoted to AFOAT-1 reporting. Position, time and altitude will be as normally reported on westher reconnaissance flights. Tho first group of the five digits group wull bo used for encode the radiation observations. Readings and general observations are to be coded in sequence and if conformance with the code below. Should the first fivo digit group not adequately describe the report, successive five-digit groups should be used. To indicate such ampli- fication, the first digit of the firet:five digit group should be coded accordingly, The numbers indicated for coding the dosired information below are oxamples only. Formal random code numbers will be assigned by CJTF SEVEN prior to the first shot for successive three-hour poriods 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.
