1. Do I know the reasons? Yes (well I know what CASA presented as their reasons)
2. Can I tell you what they are? I probably shouldn't.
3. If I told you what they are, would you consider them to be valid? Probably not.
4. Do Airservices think they are valid? The hint in the notam should answer that.
5. Was this an unwarranted knee jerk reaction? CASA says no. (not all agree)
6. Was there any safety work done on the withdrawal of the SID? CASA says yes, but it is evident that there wasn't. If there was it was far from comprehensive as Atc had no idea it was coming. Regardless, refer previous comments regarding safety assessments of our regulator.
Dick, from what I hear the local BK FOI's are also driving this in conjunction with people in the OAR. You might get some I formation from them.
Alpha.
