Aviation navigation made simple and affordable. Aviation map with airspace and TFR info, plus all VFR, low-altitude IFR and instrument approach charts for the continental United States, with full flight planning, including support for airway navigation and auto-routing. Overlays for Nexrad, Satellite, METARs and AIRMETS/SIGMETS improve flight safety, and detailed airport information (runways, frequencies, fuel, weather, NOTAMs) is at your fingertips. Use the moving map to search or select an airport, VOR, NDB or intersection and start direct-to navigation, or add to the flight plan. Alternatively enter the flight plan in text, e.g. KPAO SUNOL V334 SAC KSAC will load the full flight plan, including all airway navigation points. Instrument approach charts include the airport diagram, STARS, DPs and minimums, as well as the legend. Nearby airports are shown in green or red to indicate whether or not those airports are likely reachable in a no-wind glide. METAR, TAF, AIRMET, SIGMET, Prog charts, Convective Outlook and Wind are available as graphical and/or textual information. METARs and AIRMETS/SIGMETS can be overlayed on the map using the Layers button.
