Our 16 weeks was padded, for we Direct Entrant Hofficers, by a week (or two?) on the first part of the ATC Assistants' Course. There we learned things at the base level ... starting with phonetic alphabet, etc, and working up to Met forms and Dlight Plans ... stuff that was of course bread and butter to ex-aircrew and SNCO AATCs moving on to controlling.
Being hurled straight on to the Watch Roster is ... scary!!
