Your premise was:
Six people were killed at Benalla because our archaic airspace and procedures were designed before radar was introduced and those responsible for change never ask how it can be done better.
Yet the only people that say this roll in the ground where you wee. The procedures HAVE been changed.
...the fact that the points were not defined in the ATC database is unbelievable shocking neglect.
Why is that? Who called for the points to put into the Eurocats data? Individual groups who thought it was a good idea put it in, while not really being sure they should. There is not a single VOR or NDB approach defined in the data, is it a shocking neglect that they haven't been? What about missed approaches???
On the other hand, if the airspace is defined as you want it such airspace will revert to 'one-in-one-out', when the Seasprite wants to go IFR. Is that REALLY what you are after?
