The massive storms that rolled through the Austin Bergstrom and San Antonio areas last Friday not only put a dent in the landscape, they put a dent in the skies too.
The Austin Bergstrom (KAUS) control tower suffered significant flood damage Friday. 6 inches of rainfall in an hour caused water to come pouring into the first floor of the tower, flooding the radar room and knocking out the power. This led to transmission outages for the tower, ground control, clearance delivery and the ATIS. Similar to the Chicago Center fire last year (though this was a much smaller section of airspace), the area normally controlled by Austin Approach was replaced by a big, gaping radar hole.
By 8:45am on Friday morning, the Austin Bergstrom airport actually closed. One runway eventually opened back up Friday afternoon, but massive delays and cancellations had already taken place. All the ILS approaches were down and Houston Center had taken over the airspace normally occupied by Austin Approach control.
A temporary, emergency tower vehicle was brought in by the FAA (it’s essentially an RV with communications and a giant window) by the end of the weekend. All arrivals and departures were restricted to 17L and 35R.
Due to the radar outage, I heard there was as much as a 4 hour delay even for planes coming into Austin Bergstrom from Dallas, and that was in VMC conditions on Sunday and Monday. Tuesday and Wednesday brought IMC conditions which only enhanced the delays.
The latest news is that Austin Approach will be opening back up, but in a satellite base in San Antonio. The Austin controllers will be using the SAT radar room and will be receiving their radar picture via satellite. The approach frequencies should be up and running today or tomorrow. The Austin Bergstrom tower is up and running and most of the ILS approaches are operational at this point.
In the meantime, expect delays going in and out of Austin. If you don’t have to get to AUS, EDC, or GTU, you’re better off delaying a day or two until Austin Approach is back up and running.
