ATA President: "The federal government's (air traffic control) system is broken"greenspun.com : LUSENET : TimeBomb 2000 (Y2000) : One Thread |
OK. I am totally confused at this point. This article says the FAA has not upgraded their '70's vintage air traffic control system. WHICH systems have they upgraded and which have they not? Are the ones not upgraded compliant?What in the hell is going on??

Upgrading air traffic control systems (ATCS) is not the same as Y2K remediation.
I haven't seen enough details disclosed from FAA re what the ATCS remediation process entails/entailed.
Was the ATCS production software merely "fixed" to accommodate correct date comparisons/computations?
Were the ATCS computer platforms--that IBM said were unable to be remediated--replaced as well?
I believe this posted item focuses more on the dysfunctionality of the ATCS as a whole. It doesn't explicitly mention anything related to Y2K issues.
There shouldn't be any point of confusion derived from this loosely written piece.

compliant but broken

I wonder if the cost of delays in relation to the number of delays can give us a metric to measure possible Y2K effects by? After all, Y2K is likely to cause alot of delays as well. I imagine we'll have to take in to account that things that travel by airliner are ussually urgent.Just my musings.
Keep your...

Robert, why don't you send those questions to Fox News. Maybe they will do a story on it. I know it is a long shot, but you brought up some good questions.

I don't know about the fixing of the FAA ARTCC system, but I can give you a bit of perspective about how the system works. I spent 37 years in the industry, but have been retired for the last 6+ years. To go from Laguardia (LGA) to O'Hare (ORD), and for those who don't know that is New York to Chicago. There is a very specific route that is used almost all the time doing that flight. It is called the prefential route and almsot every city pair has one. Out of LGA you go up over Buffalo and across the southern portion of Canada to Sarnia/Port Huron, then over Flint, MI to the eastern shore of Lake Michigan and into ORD.(It may be different now as I haven't flown that for over 10 years.) If you have weather on that route that is causing big problems, they don't reroute you, they tend to hold you on the ground because when aircraft start detouring weather with their own airbourne radar it takes more time and airspace to do this. Also if some weather is at ORD, then holding begins to come into play and you get airspace saturation. So it makes sense to space aircraft out a great deal more. Now right south of this route LGA ot ORD is the east bound route back from ORD to LGA, so you can't allow the aircraft to infringe on that area too much even tho you have altitude protection, either 1000' or 2000' depending on how high you are. If you are airbourne, is is possible to get a reroute to avoid weather if you have enough time to wait and fuel already on board to fly the new routing. Additional fueling could cost you at least a half hour and you may miss your slot to leave. And occasionally the dispatchers, who are the ground folks who have a joint responsibility with the Captain for the safety of the flight, can get a new routing from the Air traffic control folks, but often not right away as it tends to screw the system up further. The reason being for this problem is that most places like ORD have four arrival fixes where all the aircraft arrive over. If too many are rerouted, then some of the other arrival fixes get saturated and you cause rippling problems. The airways are very sharply defined space you are allowed to fly in and there are very specific points you are required to fly over, even tho it looks like there are millions of miles of open sky up there. Also the airlines tend to be their own worst problems as they want the banks of flights to arrive and depart within a very specific time frame to make connections and to maximize profit. Works well most of the time, but throw in snow or thunderstorms and it comes apart in a hurry. Hope that helps some.
