Respected sirs,
I'm sorry to inform you that, while your piece is partially correct in that our air traffic control system is out of date, it is grossly incorrect in its conclusions that this antiquated system is the cause of so much congestion and delay in commercial air travel today.
What would be the point of converting a 2 lane highway to 4 if the drivers all had to squeeze down to 1 lane to go through a 4 way stop? Absolutely none, right? Well, improving ATC, which is important of course, would be widening the highway, but the 4 way stop remains untouched.
As a private pilot, I deal with air traffic control regularly. Yes, they are busy, but even so, it is a very big sky out there, and it is vastly empty - except in a few, very important areas.
Where the source of the problems exist should be self-evident. Where, when you look at air traffic patterns, do congestions occur? Around major cities, of course. Why do the congestions occur?
Not because ATC is over-burdened (note, please that I am not saying they aren't), but because there is a physical limit to how much traffic can be squeezed onto a given runway in an hour.
It would be extremely unsafe to allow more takeoffs and landings to happen than already happen when at the major airport's busiest times, because there simply isn't anywhere else for those planes to fit. However, even when the local major airport to me is at its peak operation, I can easily and without delay get worked into the air traffic control system when I depart from my relatively small, and quiet, community airport.
Airlines know when their passengers want to fly, and book their flights accordingly, and contrary to popular belief, takeoffs and departures ultimately tend to fall into a first-come, first-serve arrangement. If you're ready to go 5 minutes early, you're not going to be kept sitting on the taxiway holding up the people slotted for 5 minutes ago, are you?
In short, what is needed most of all is more runways. At a major airport with 2 runways, adding 1 or even 2 more runways would increase the ability of airlines to get planes into the air, or on the ground, during the busiest times. Departures and arrivals could happen with greater frequency during those early morning and late evening rush times (and one or two additional tower controllers would round out the need for coverage), while during off peak hours, the airport could drop down to single or double runway use, send one controller home, and optimize efficiency.
Of course, the ugly truth here is that funding an ATC systems upgrade is relatively easy, compared to the public relations battle involved with any airport expansion.
Still, America's public will have to come to terms with the truth that they can't always have their cake and eat it too. If they want more efficient airline travel, they either need to be more willing to fly at off hours, or they need to give up precious land near the commercial centers of the country to allow more planes in and out when they want the planes to be flying.
Respectfully,
