My other concern is knee-jerk reactions. As stated in the Flight Safety article, the GAAP changes were rushed through because of the mid-air statistics.
Now 2 things are relevant here. Firstly, the statistics did not show a statistically significant trend in mid-airs - we did have a bit of a cluster but that is not uncommon in random, extremely low incidence events. So there was no need to rush in with poorly thought through changes.
Secondly, long term the changes may in fact increase the risk (eg by increased holding times at GAAP approach points while waiting for clearance). Plus the change to Class D means that AsA needs more ATC's (which they don't have).
My tip is the GAAP to Class D changes will be deferred, possibly for quite some time (HINT: the CEO in the interview makes a great point of "well, we'll act quickly to make changes, but if there are problems then we'll just defer implementation then everyone's happy" - so he's already preparing for the inevitable backdown). BTW, what's the difference between deferring the change on the one hand and making the change and deferring implementation on the other - seems curious logic, dare I say spin!
Given this background I really worry about what might happen if we had a couple of major RA accidents in a short time - despite probably having no statistical significance you can bet that the new CASA would come down on us with great force.
