About this app

Kovac brings together in a single app the weather information you need before takeoff, designed for drone and general aviation pilots.

FLYING WEATHER
• Current conditions at your location or anywhere you search.

• Flight suitability based on your drone's profile: evaluates wind, gusts, visibility, probability of rain, and Kp index.

• Wind by altitude: how the intensity and direction change as you ascend.

• Cloud layers and their altitude.

• Useful flight hours with sunrise and sunset times.

• Geomagnetic Kp index, which affects GPS accuracy.

• Compass: point your phone and see the wind direction.

• GOES-East satellite imagery with overlaid active SIGMET data.

FORECAST
• Hourly forecast for the next few days: wind, gusts, cloud cover, precipitation, visibility, and pressure.

AIRFIELDS
• METAR and TAF data decoded in plain language, with flight category (VFR, MVFR, IFR, LIFR).

• Search for any aerodrome by ICAO code, with suggestions by name or city for aerodromes in Argentina and major aerodromes worldwide.

• Active SIGMET.

AIRSPACE
• Map showing nearby controlled and restricted airspace zones.

• Obstacles recorded in the area.

NO ACCOUNTS OR ADVERTISING
Kovac is free, requires no registration, and displays no ads.

DATA SOURCES
Open-Meteo, aviationweather.gov (NOAA), NOAA SWPC, NASA GIBS, openAIP, and OpenStreetMap.

IMPORTANT NOTICE
Kovac is a supplementary reference tool. It does not replace official meteorological information or current aeronautical documentation (AIP, NOTAM) for flight planning. The pilot is always responsible for each flight.

What’s new

• Airspace: updated the app to handle a change in the external aviation data service that prevented nearby airspaces and obstacles from loading.
• Data now loads faster when checking multiple locations in the same country.
