I have been writing this since Friday when the outage began (it took that long for the SITREP Stan!). Things have been a tad busy here so I've been adding to this in bits and pieces in when I can.
I won't speak about the ZAU fire. All I can say to those who don't know how ATC works is that the NAS is a system designed with multiple layers of redundancy. This is the first time since 1962 that ZAU has not had at least one controller manning a frequency and keeping an eye on the skies over the region.
Let me say that again.
The FIRST time.
Since 1962. Every other outage, equipment failure, or hiccup ZAU suffered, traffic kept moving and controllers still worked airplanes through the system. Even years ago, when ZAU lost automation capability, we worked the traffic and got siht done. The average Joe didn't hear about those things in the news.
We (too many ATC facilities to list) are making things work right now, but have to manually coordinate all flight plan and aircraft information between facilities. Since Chicago TRACON doesn't abut the ARTCC's that have assumed ZAU airspace we did not have landlines with those sectors and controllers. Every coordination call required a regular landline telephone call (i.e. 123-456-7890) to affect flight plan forwarding and radar handoff coordination. Saturday, one of our technicians figured out how to get shout lines for us, which has been a considerable help in affecting coordination. Today we further streamlined how we affect manual coordination between neighboring facilities.
ZAU controllers have been helping at Chicago TRACON since Saturday. ZAU controllers are now enroute to all neighboring facilities to aide in coordination and manual flight plan processing.
We need the help. We are back to the 1950's-1960's. Back then, ATC needed two to three controllers per sector to work traffic through the NAS. Without automation, the amount of manpower required to work traffic into and out of these airports is staggering. Every single flight plan needs manual coordination: call sign, type aircraft, requested altitude, route of flight, beacon code, and any other pertinent information. Every aircraft requires inter facility coordination to affect a handoff: location, beacon code, altitude, call sign. I've never been more proud of my colleagues and the work done to get things moving like we have done. I can't begin to describe the amount of teamwork and fortitude my fellow controllers have exhibited thus far.
We are learning as we go and there are parts of ZAU airspace with zero radar coverage. It's not just Chicago TRACON that is dealing with the ZAU outage. Every facility in and around ZAU faces the same challenges. For those of you flying around ZAU and surrounding airspace I can only say one thing.
Please be patient.
