The department has checked and redesigned many calculations for VOR DME holding patterns. The above graphic is the result of a recent project undertaken near Geneva. Swiss Control were able to utilise the power of the Wavionix hold design tool to rapidly explore which combination of altitude and airspeed would provide the optimum reduction in hold area to better utilise the available airspace. This graphic shows the vertical cut for Les Eplatures, a high altitude aerodrome, which is located in the Jura mountain range. The aerodrome level is depicted on the bottom line and the minimum altitude is shown on the white line, the green line indicates the lowest approach path.
Lower sector are the Geneva sectors.
This was a study on an area near Konstanz where 850 obstacles were listed. Using Wavionix an obstacle file was created automatically and this took a few hours to complete as opposed to a few days if working manually. All obstacles are listed automatically Obstacles can be rapidly identified graphically when the drawing is shaded. New ILS Procedure at Berne Airport Runway extensions have either been carried, or are about to be carried out at practically all Swiss aerodromes this means that all the procedures have had to be re-calculated. This graphic is an example of this work on a new ILS procedure created for Berne airport to facilitate its new runway extension.
