1. Primary Radar does not provide altitude information.

2. Can you please specify how, in your opinion, the integration of military and civil ATC would increase the workload?
Fact is, that civil ATCOs will continue handling civil traffic and military ATCOs will continue handling military traffic.
Why should it present an obstacle to an integrated European ATC concept?
And if you think that a Single European Sky will ultimately lead to a safer sky, then ask IFATCA, what they believe...

3. Let me quote from a media release by the BFU concerning the report of 26.June 2002 and the collision:

"Ein zweiter Messflug am 5. Dezember 2000 lieferte Daten, die bezüglich der erwähnten Genauigkeit wesentlich besser waren. Die Vorgaben von Eurocontrol an die Genauigkeit der Darstellung auf dem Bildschirm zur Sicherstellung der minimalen seitlichen Separation wurden zum grossen Teil erfüllt.
Zum gegenwärtigen Zeitpunkt gibt es keine Hinweise darauf, dass die Präzision der Positionsdarstellung der Flüge DHX611 und BTC2937 ungenügend war."

(A second calibration flight on 5.December 2000 delivered data, which were substantially better concerning accuracy. The requirements of Eurocontrol concerning the accuracy of the display on the screen in order to ensure the minimal lateral separation were met to a high extent.
At this stage, there are no indications, that the precision of the display of the positions of flights DHX611 and BTC2937 was insufficient.)


"Bezüglich der Kollision von Flug DHX611 mit Flug BTC2937 vom 1.Juli kann festgestellt werden, dass die verunfallten Flugzeuge durch die Sekundärradarsysteme kontinuierlich erfasst und auf den Bildschirmen des Flugverkehrsleiters dargestellt wurden. Der Umstand, dass keine primären Radarquellen zur Verfügung standen, hatte nach gegenwärtigem Erkenntnisstand keinen Einfluss auf das Unfallgeschehen."

(Concerning the collision between flight DHX611 and flight BTC2937 on 1.Juli 2002 it can be stated, that the aircraft had been continually picked up by the secondary radar system and had been displayed on the Air Traffic Controller's screens.
The fact, that there was no primary radar source available had, according to the present level of knowledge, no influence on the accident.)
