SkyAware is your intelligent aviation companion, built for student pilots and seasoned professionals alike. Get real-time weather intelligence, AI-powered safety analysis, terrain awareness, and comprehensive flight planning tools — all in one app. KEY FEATURES Real-Time Weather Intelligence Search any airport by ICAO code to instantly view decoded METAR data, flight categories (VFR, MVFR, IFR, LIFR), wind conditions, visibility, ceiling, altimeter settings, temperature, and dewpoint spread — all presented in a clean, color-coded layout. AI-Powered Safety Scoring Every weather report is analyzed by AI to generate a 0–100 safety score with clear, plain-language summaries. Know at a glance whether conditions are favorable before you fly. Nearby Airport Discovery Use GPS to find airports within 10, 25, 50, or 100 nautical miles, each showing live flight categories so you can quickly assess conditions across the region. Interactive Flight Planning Plan routes on an interactive map with custom waypoints, weather overlays (METAR, SIGMET, AIRMET), and terrain visualization. Import FPL files to analyze existing flight plans. An AI scanner suggests safe alternate airports based on weather and terrain along your route. Terrain Awareness Real-time terrain elevation data helps you identify ground proximity hazards during both pre-flight planning and in-flight monitoring. Get alerts when terrain clearance is insufficient for your altitude. In-Flight Mode Switch to active flight mode for real-time GPS position tracking, continuous hazard monitoring, and live weather updates along your route. If an emergency arises, the app evaluates nearby airports and generates aircraft-specific emergency checklists with memory items and key speeds. Ideal Runway Indicator A visual runway widget calculates and displays the recommended runway based on current wind direction and speed. Sun Phase Tracking View sunrise and sunset times in both local and Zulu time with a visual day/night progress bar — essential for planning around daylight hours. Customizable Units Choose your preferred units for distance (nm, km, mi), altitude (ft, m), pressure (inHg, hPa), and temperature (°C, °F). Light & Dark Mode Switch between light and dark themes to suit your environment, whether you're planning at home or flying at night. DATA SOURCES SkyAware pulls from trusted aviation and meteorological sources including the Aviation Weather Center, Open-Meteo, and a comprehensive global airport database.
