Let's save them.
If you think that GA only consists of the city based flying school and some hobbyists looking for cheap flying(don't we all?), then yes GA is probably dying. The young pilots are getting smarter and communication is getting better, so the rumours of the numerous skygod jobs are no longer brining so many chequebooks to the flying schools. The flying schools have to change. Those with some sort of agreement with airlines will spend the money for a multi crew licence but many others will not.
The real value of GA is outback, like PNG, where other forms of transport are not so good. And that demand will be there for a long long time.
And there are some good airframes out there that will die if the present trend continues. It is now well proven that many aircraft survive for half a century if they are properly looked after. {look at our military).
Chuckles Bonanza will serve him well for many years, and will be as good as a new one when he finishes refittnig it. I applaud his efforts
I remember seeing a beautiful Cessna 340 a few years ago. It did not look nice at the time. It was covered with dust and bird****. It was about 30 years old and had flown 300 hours.
There is treasure out there. Some of those machines the "junior skygods" call ****boxes, are in fact quite valuable.
GA will not die in Australia. It will change a bit, but it will not die. It is too important.
