Generally "flight security" is only associated with the "tower" whereby other jobs done by the approach control point for the airport in the 3 floor of the administration building is of no less importance but is not considered very often. This happens mostly due to the striking appearance of every airport control tower and that people tend to see the tower as a kind of identification mark of the airport.
In the Tower
The air traffic controllers who carry out their duties at the top of the control tower in their glass flight station have the task of ensuring that all flight traffic in the so called air control zone around the airport can flow without crashing and that all aircraft can take off and land in an orderly way. The control of this so called "airport traffic" is guaranteed for the main part through direct visual contact of the aircraft to be controlled. A radar screen is also used for support and above all for the purpose of traffic planning. Furthermore, the tower also steers and co-ordinates all moving aircraft and aircraft actually on the runway. This job necessitates direct visual contact and this is why the work place is situated so high up on the tower as this ensures the clearest overview possible.
The Flight Approach point
The flight traffic control is not only situated in a different space, but their area of duty is also varied: obviously the air traffic controllers who work in the new "approach space", are not instructed by the direct visual contact with the aircraft in their area of responsibility. Although they have to make sure just as their colleagues in the tower do , that air traffic flows freely in its air space, the use mostly only the information provided to them by the radar equipment. The use of this highly technical system allows for greater dimensioning of the air space to be controlled. In Salzburg's case this so called "Radar Area" not only covers the greater surroundings of the Provincial city but also parts of Bavaria East of the town of Traunstein. Towards the South this area stretches in to a narrow corridor to the Alpenhauptkamm (mountain range). In an upwardly direction this air space is limited by a flight altitude of 12.500 feet (approx. 4,000m).
Departing aircraft directed by the air traffic controllers to further flight routes which are relevant to their flight path or airway, as long as they are located in the air space described.
