QSkyway — navigation layer for the urban sky
Provider-independent 3D air corridors for air taxis — live on real buildings in Astana, New York, Tokyo, Singapore, Amsterdam, Berlin, Vienna and Zurich, routed against what the regulators actually publish (FAA airspace ceilings over Manhattan, Japan's MLIT permission regime, CAAS permits over Singapore, the Schiphol CTR from the Dutch eAIP over Amsterdam's Zuidas, ED-R 146 from the German AIP over Berlin's Potsdamer Platz, the LOWW control zone from Austro Control's own airspace feed over Vienna's Innere Stadt, BAZL's drone geo-zone ceilings over central Zurich, Kazakhstan's published prohibited area over the Astana twin).
Live METAR wind, height-data provenance, an airspace-slot rights market, and every flight exportable as a signed justification document. The interface follows your browser language — English out of the box, with a switcher in the header for Russian and Kazakh.
