Notwithstanding the earlier comments re Ansett FEs and their integration into the flight deck environment on both the B727 and B747, my experience with Australian Airlines was quite different.
Having spent 10 years flying the P3B/C Orion in the RAAF, I retired and joined Australian in late 1987 to fly B727-200.
At the time I joined Australian, I was not aware (and was not expecting) that there were any differences between the integration levels of the FE between the RAAF and Australian/Ansett Airlines.
When I left Australian in 1992 I was still unaware of any such differences. I found out only after reading about this Ansett B743 accident, and subsequently bringing up the subject with an ex-RAAF, ex-Ansett FE I knew quite well.
