Mr Fairless,
Please do not suggest there is actually some cogent strategy behind the ASA proposals or that there is sufficient experience and knowledge in CASA to present all the options. Fantasyland indeed.
Although the report is over a decade old now, CASA RFQ 09/342 had some potential to at least open the gate but never saw the light of day because, the authors tell me, CASA thought it made several of their past decisions look stupid. Probably more so now.
