There is Nothing good about Privatization, that I can think of. It never worked in any Country that tried it. I know that some people to the North think it works for them but every time they come here they realize that what they have is Not working as well as what we have here. I don't even want to bring up other locations where pilots / GA has basically been eliminated by fees and privatization.
I am very surprised that the present Admin proposed this, I did not expect this from a real businessman. If a business needs fixing, you fix it, not trash it / give it away for nothing. I guess if the business is not one that you invested your own money and effort in, it's useless / dispensable, let someone else have it?
ATC can be fixed, no need for a privatization, a private company can do no better, what is needed is a good Manager. We expected this Admin to come and fix things not give them away. Get a Manager that knows what to do, start by eliminating the Unions, another form of Communism in my opinion, I know that is never likely to happen since they feed many of our leaders / politicians, but they can be trimmed down / controlled, if you really want it. The same approach that is now being taken to fix VA can be used to fix the ATC, people that Know what they are doing, and Want to do the job.
If the privatized ATC will try to eliminate / charge for Flight Following, giving headings and vectors, filing IFR ... by GA, this will turn into a terrible safety issue in many areas. In addition many of the Commercial flight will likely be delayed, and in the worst case mid air collisions are very likely. ADS-B will not fix that problem, if you are not talking, and get headings / vectors you will not be able to avoid it.
Compounding the problem is going to be other aircraft that people may use to avoid fees, Drones etc. all buzzing around in uncontrolled airspace interfering with commercial operations.
Add to that the fact that GA is now providing most of training for the Commercial pilots, for free, and this will like go away. There are some companies, presently, already having to pay to train for their own pilots. This alone will cost them Millions if not Billions of Dollars, to get someone to accumulate the experience / hours needed to provide experienced / safe pilots. The only way around that would be to allow commercial pilots with fewer hours to be employed, which in itself would jeopardize safety, we all know that there is no substitute for experience / time in the aircraft.
I do hope that this does not get approved by Congress, or better yet, retract it now.
