I was a RAAF trainee pilot in 1955 /56 . We flew tiger moths from Uranquinty and also Wirraways . AFTS was at Pt Cook where we flew those instrument patterns regularly. Later I was an instructor on Winjeels (1959) at Pt Cook where we tought the same patterns. I am afraid I cannot remember them very well but they were nothing like one of the previous comments . They basically consisted of timed climbing and descending turns so that the required heights and headings were achieved in the correct seguence
