E6b Pilot puts a complete electronic flight computer in your pocket. Inspired by the classic E6B whiz-wheel and designed to replace bulky handheld units, it brings every calculation a private or professional pilot needs into one fast, clear, modern app. No fiddly buttons, no clutter. Results appear the instant you have entered enough information — just type, and the answer updates live. A dark, glare-friendly "glass cockpit" interface keeps readouts sharp on the ground or in the air, and graphical wind triangles and runway diagrams show you what the numbers mean at a glance. WHAT YOU CAN DO Flight planning, all in one place Build a complete single-leg flight plan on the home screen — track and distance, heading and ground speed, fuel and time, weight and balance, and optional trip costing. Change one value and dependent results flag themselves for review, so your plan always stays consistent. Wind, made visual Solve the wind triangle for heading and ground speed, track and ground speed, or unknown wind. Crosswind and headwind components are shown on a runway diagram, and a compass-rose visualiser plots your track, heading and wind together. Altitude and airspeed Pressure and density altitude, true altitude, and full TAS–RAS–Mach conversion with local speed of sound — plus the ISA 1976 standard atmosphere at any level. Vertical navigation Rate of climb and descent, top of climb and top of descent. Performance and safety Turns and load factor (g, stall-speed rise, rate and radius of turn), Defined Minimum Manoeuvring Speed, carburettor icing risk from temperature and dew point, estimated cloud base, and VHF line-of-sight range. Conversions Volume, weight, distance, temperature, pressure and airspeed — plus a specific-gravity-aware volume-to-weight converter for accurate fuel figures. Utilities Holding pattern computer, critical point, point of no return, sunrise and sunset, live weather (METAR and TAF for any ICAO airfield), a stopwatch, and a time calculator. DESIGNED FOR REAL COCKPITS Live calculation — no Calculate button to press Dark, high-contrast display that's easy on the eyes Large, tappable fields with clear units and negative-value entry "Show workings" on newer tools, so the app doubles as a learning aid Built for iPhone and iPad Whether you're a student pilot learning the theory, a PPL holder planning a weekend trip, or a professional cross-checking figures, E6b Pilot is the flight computer that keeps up with you. Fly safe. Note: E6b Pilot is a flight-planning and training aid. Always cross-check critical calculations and comply with your aircraft's approved documentation and applicable regulations. Weather data requires an internet connection.
