Losing money in aviation - general aviation statistics

General aviation statistics - why are businesses losing money?

The Bureau of Transport and Communications Economics’ most detailed survey on general aviation indicates that in 1993 a typical flying training organisation holding an AOC employed five people specifically for aviation. The organisation owned 3.5 aircraft of an average age of 15 years. They flew just under 900 hours per year and recorded a pre-tax operating loss of $743 per annum.

This is absolutely staggering. Compare this to the telecommunications industry in Australia which has an 8% growth rate.

I understand from talking to flying school operators that most of them can barely manage to pay their own salaries (which on average are about half that of air traffic controllers) let alone make a profit each year.

Does anyone have more recent figures?
