What complacency? When was the last time you sat in on matrix sim. session with one of our major carriers Dick? The "IAS Disagree Non-Normal",if that's what turns out to be the cause,is trained to competency in all major carriers in Australia.Have a chat to Trainers who have actually worked with our northern neighbors.You might get a reality check.They have a very real problem.Their hull-loss rate is off the scale.I personally have had several incidents in Indonesian airspace that made my hair stand on end.Comparing the Indonesian aviation environment with Australia's is simply ill-informed. Stick to GA Dick .And don't let your family fly domestically in Indonesia.
