The Ansett 4 LRs had:
Omega Navigation
Autothrottle
Autobrakes
Fwd aux fuel tanks
Aft aux fuel tanks
(Both aux tanks were fixed units, removable, but not palletised.)
Capt Lionel Griffiths sadly passed away about 3or 4 years ago. I flew with him on a delivery flight (VH-ANF) to Miami after they were sold by Ansett.

Most of them returned to Auz as freighters.
