Airspace Classifications, Coloring and Labeling
The coloring and line types and widths of airspace classes, sectors, zones and restrictions are reproduced as close as possible to ICAO guidelines and recommendations. Currently the following distinctions regarding the visualization are being made:
Airspace Class A: is visualized with a thin red outer line and a wide transparent inner band of the same color.
Airspace Class B, C and D: are visualized alike class A but with a thin blue outer line and a wide transparent inner band of the same color.
Airspace Class E, F and G: come with the same blue outer line as B, C and D but lack the wide inner band. For E the outer line is a bit wider.
Control Zone (CTR): airspace control zones (CTR) will be displayed as an area with a blue dashed outer line and a transparent red shading covering the whole CTR.
Radio Mandatory zone (RMZ): airspace radio mandatory zones (RMZ) are visualized with an area with a blue dashed outer line and a transparent blue shading covering the whole RMZ.
Transponder Mandatory zone (TMZ): airspace transponder mandatory zones (TMZ) are depicted using a thick dashed black line with alternating line segment length.
RESTRICTED and DANGER: restricted, danger or prohibited areas are being visualized with a thin outer red line and a wide red hatched inner band.
Currently no explicit tags are added to the airspaces visualized on the map. Information regarding lower/upper levels and frequencies are show in the airspace info box.
