The devil is in the details, though. Where are the user fees collected from, and what are the proceeds spent on? Are these for airport improvement, or for ATC directly? What will the military and government users pay into this system, as they are also substantial users of it.
The majority of the aircraft in the US are GA, which is (fortunately for us) something that is unique in the world. Personally, I can mostly avoid using ATC services, at the expense of more fuel and less safety in my case. That isn't a good solution. Improvements need to start with ideas that will benefit everyone.
The majority of aircraft may be GA, but the majority of those are parked, the majority of the time. The majority of the use of the system, comes from 121 operations. All three major airlines, together, account for over 14,000 departures, A DAY. Let that sink in a minute.
Now, does GA sound like the problem here, or is someone just poking the hive again. The article didn't even mention user fees, correct?
