AviNavi, navigation for pilots

Aviation navigation made simple and affordable. All VFR, low-altitude IFR and instrument approach charts for the continental United States, with full flight planning, including support for airway navigation. Overlays for Nexrad, hazardous terrain, METARs and AIRMETS/SIGMETS improve flight safety, and detailed airport information (runways, frequencies, fuel etc) 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 can be loaded by state or by route, e.g. ORD TO JFK will load all instrument charts for airports along this route. Approach charts include the airport diagram, STARS, DPs and minimums, as well as the legend.
Nearby airports are shown in green, yellow 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. Airport information shows METARs and TAFs in plain English, and tapping WX (or selecting Weather from the menu) will show Prog charts, Convective Outlook and Wind graphics that can be zoomed into.

AviNavi is free to use with one VFR and one IFR map. For full continental coverage and approach charts, a $9.99 annual subscription is required.
