      Quick thread about Air Traffic Control and why privatizing it is a shit-terrible idea. Note: I spent most of my career in aerospace.

      There's a reason why Seinfeld jokes about "final approach" are so dated. It's because we've made huge gains in ATC over the past two decades

      Airlines don't care about flying faster, flying farther, or flying bigger. They want to fly cheaper. That's all that matters.

      A big part of this is fuel. Back in the day, e.g. when the Air Traffic Controllers went on strike, airplanes carried a lot of extra fuel.

      Fuel = weight, weight = more fuel spent, more costs. The perfect fuel load will be nearly empty when you land.

      But back then, ATC was very manual, and it wasn't uncommon to have to circle in a holding pattern waiting for landing clearance.

          This still happens from time to time, but thanks to modern technology and training, we have improved on this.

          Controllers will know well in-advance when the flights are arriving and can begin landing procedures almost an hour before the plane arrives

          Technologies like ERAM (En-Route Automation Modernization) can predict backups in-advance and deconflict in advance.

          All of this requires intense, standardized coordination across the national airspace, i.e. exactly the thing primed for nationalization.

          Privatization of ATC will make the NAS look more like the National Power Grid. A hopeless mess held together by duct tape and expertise.

          It will cost the airlines money. Which will mean businesses and consumers spend more money and fly less. This is bad for business.

          The mathematics behind air traffic control are some of the most interesting I've ever encountered. This is in the public benefit.

          If you ever want to dive into the intersection of ops engineering, data science, and operations research, ATC is a deep rabbit hole. FIN.

          Much of this technology is developed by private industry with support from NASA and the FAA. Private industry is benefitting already.

          From research firms to the companies building the technology and software, this is an example of working government-corporate relations.

          While there is room for improvement, there is no need to sabotage the progress being made here. It's nonsensical.

          Ahhhhhh so this is why I grew up thinking holding patterns were normal, but my plane has always seemed to land immediately. That's neat.

          I have not circled in ~20 yrs. The reality is planes are full packing more passengers in, more seats, bags don't get lost anymore,

          The "racetrack" holding patterns over JFK and LGA were amazing in the 1960's. At Idlewild, now JFK, had 727s in every 45 seconds.
