GA???
The words "general aviation" really mean any kind of flying,in any sort of flying machine.
But the aeroplane sales people thought that the term "light aircraft" would not help them sell aeroplanes, so they encouraged people to use the term "general aviation" instead to describe the non airline aircraft.
Today the term GA is commonly used to describe the non airline aviation industry that has been almost destrroyed by floods of airline wannabies and manipulators who thought they would only be doing it for a short time and many of whom were prepared to work for peanuts and cut corners to try to get ahead of their "mates" There were many good pilots but most of them got demoralised and left.
Airlines are now finding that they should have had a long term plan for recruiting, so they don't get caught with a shortage of pilots. Things are now changing, and GA may recover.
That is what "GA" is. And 80% of the country depends on it.
