Citing last summer’s midair collision between a DHL International Airways Boeing 757 and a Bashkirian Airlines Tupolev Tu-154 over southern Germany, the NTSB has recommended that the FAA modify its ATC data-processing backup systems to provide conflict alerts to the greatest extent possible.

The collision occurred in a corner of the en route portion of the Zurich, Switzerland  area control center’s airspace (near the northeastern limit of the controller’s area of responsibility) while both airplanes were operating under IFR and in communication with ATC personnel at the facility. A single controller in Zurich was responsible for en route airspace in the eastern half of Switzerland, portions of southern Germany and an approach control sector in the vicinity of Lake Constance, Germany, encompassing the Friedrichshafen Airport.
