Airspace, Geo-Zones, NOTAMs & Live Traffic

The planner can enrich the map with four independent overlays. Each one is fetched for the current map viewport and updates automatically as you pan and zoom. All overlays are advisory only — always verify with official briefing sources before flight.

Airspace

The airspace overlay draws controlled airspace, navigation warnings, danger/restricted areas, and obstacles as colored polygons, based on open flightmaps data. A filter menu lets you toggle individual airspace categories, so you can, for example, hide gliding sectors while keeping CTRs and danger areas visible. Clicking a polygon opens a popup with the airspace name, class, and vertical limits. In US viewports, active Temporary Flight Restrictions (TFRs) are included automatically. In the 3D view, airspace is rendered as volumes between the published lower and upper limits.

Drone geo-zones

The geo-zone overlay shows national UAS geographical zones (ED-269 style) published by aviation authorities — for example the Swiss BAZL drone restriction dataset. Zones are numbered on the map, and the matching list in the planning panel shows each zone's type and restrictions; selecting an entry in either place highlights it in the other. When your viewport spans multiple countries, a per-country filter lets you show or hide each country's zones individually.

NOTAMs

The NOTAM overlay places numbered markers on the map and lists the same NOTAMs — with decoded text — in the planning panel, DABS-style: the marker number on the map always matches the list entry. Two filters keep the list manageable:

• Scope — e.g. aerodrome vs. en-route NOTAMs.
• Category — e.g. airspace restrictions, obstacles, or navigation warnings. Your category selection is remembered on the device.

Hovering a NOTAM marker reveals its affected radius as a circle; a refresh button re-fetches the current viewport. NOTAMs are sourced from a keyless public provider by default.

Live air traffic

The traffic overlay shows nearby aircraft from the community ADS-B network adsb.lol, refreshed every 10 seconds while the tab is visible. Each aircraft icon is rotated to its track and colored by altitude, and its tooltip shows callsign or registration, aircraft type, and altitude. Coverage depends on volunteer receivers — the picture may be incomplete or delayed, so never use this layer for collision avoidance. It is meant for situational awareness, e.g. spotting a busy helicopter route near your planned area.

Attribution & disclaimers

While any overlay is active, an attribution note appears in the map corner naming the data source and its license. These datasets come from third parties, can lag behind reality, and are provided without warranty — they support your pre-flight assessment but never replace the official briefing required by your aviation authority.
