Gee Dick, nice graph. How do you conclude from that graph that the drop in GA hours is because of 'use of airspace' charges?
There is no correlation.
What will your conclusions be if the downturn continues despite the introduction of NAS?
To put it simply, the airspace system before 27 November 2003 added millions of dollars to the cost of general aviation.
Again you pull out this old chestnut, without proof of the facts and figures. Please advise of your source for this alleged cost savings.
Another pointless posting from Dick.
