E6B-Pro

E6B Pro is a digital flight computer for student and private pilots. Use it on the ground to cross-check density altitude, wind, fuel, and a VFR navlog before you fly. This app is a training and preflight aid. It is not certified navigation equipment and does not replace your POH, AFM, official weather briefing, or the pilot in command. CALCULATORS • Density altitude and pressure altitude (elevation + altimeter, or METAR) • True airspeed (compressible CAS→TAS) and Mach • Wind components, wind correction, and crosswind vs runway limit • Fuel planner with VFR day 30 / night 45 / IFR 45 min reserves • Time, speed, and distance • Cloud base, descent / top of descent, climb gradient • Weight and balance • Holding, turn performance, pivotal altitude • Course and distance between airports (great circle, true and magnetic) • Off-course / 1-in-60 intercept • Aviation unit converter (NM, kt, Avgas, Jet-A, and more) WEATHER Look up ICAO or IATA (KJFK or JFK). METAR and TAF from FAA aviationweather.gov with NOAA fallback. Decoded wind, vis, clouds, flight category, CAVOK, and station elevation. Send a METAR into density altitude, TAS, wind, and crosswind. AIRPORTS Search 5,700+ large and medium airports. Elevation, runways, and magnetic variation from WMM2025. Autocomplete on weather, calculators, and navlog waypoints. NAVLOG Build a multi-leg briefing log: ETD/ETE/ETA (Zulu), fuel on board vs trip plus reserve, MAG or TRUE north. Apply METAR wind to all legs. Export a PDF navlog. WIDGETS Home Screen widgets open a calculator, weather, navlog, or converter. Designed for iPhone in a dark cockpit layout. One purchase, all features. Always verify figures against approved sources. You are responsible for the aircraft and the flight.
