Just a reply to FFRATS. Everything I have read in the latest Flt Ops news letter and available on the QF Intranet suggests that the -300's will be upgraded with GPS updated CMA-900 FMS,triple Litton LTN-92 IRS,ACARS, Satcom etc, but only EHSI. My reading suggests that the mechanical ADI remains and that as no performance data is available to the FMC then VNAV and performance predictions are not available. It goes on to say that a Geometric VNAV will be a future addition expected on Qantas aircraft in early 2004. While the VNAV path would be displayed at that time, I don't believe they will be able to couple the autoflight system to it but rather use it as an indication with regards to high or low on computed profile.
Cheers..
