Wondering if anyone can help with a copy or scan of the "pattern B" sequence which was used during instrument flying training in RAAF Winjeels.
The basic pattern included straight legs and turns as well as climbing and descending - 4 straight legs, 4 turns.
Thanks

I flew Winjeels in 69 and 72, never heard of Patterns. The only prescribed tracks we flew were the VDF Letdown. "Dual 58, transmit!" "Dual 58, one two zero, three zero zero zero" (before they switched to thousands) "Dual 58, steer one two eight, descend to two five zero zero" etc

Pattern B was upper airwork, not an instrument descent. It was a significant part of upper air training when I was a student at BFTS 1961. Funny, don't recall it when I did the instructor course at CFS in 1966.
The only way I mastered the exercise was to learn, by rote, the required attitude, heading, speed, altitude, vertical rate at every 15 seconds for entire pattern. Took about 10 minutes to fly the pattern.
Perhaps someone may remember some of individual legs of the pattern?

was it something like this?

Thanks Jonkster, similar idea. The turns were 270 degrees (I think) with descent, or climb and roll out on required heading at the same time as hitting the target altitude.
Pretty well just a square box with some sort of turn (at least 270 D) at each corner.

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
