Thank you for using Flight Calcs. Your attention to fuel, weather, loading and timing is good airmanship. Keep useful numbers close from preflight to the debrief, with aviation calculators, airport references and saved records on iPhone and iPad. FLIGHT PLANNING AND E6B - Solve heading, wind correction angle, groundspeed, time and distance. - Practice with the visual mechanical E6B simulator. - Check runway crosswind, headwind and tailwind components. - Estimate trip fuel, reserve fuel, endurance, climb and descent. - Calculate true airspeed, Mach, pressure altitude and density altitude. - Review cloud base estimates and holding pattern entry guidance. - Build NavLog legs with checkpoints, ETA, fuel and route notes. - Convert knots, nautical miles, gallons, liters, pounds and more. WEIGHT AND BALANCE - Choose from eleven searchable aircraft planning templates. - Enter occupants, baggage, equipment and usable fuel by station. - Compare zero-fuel, ramp, takeoff and landing weight and CG. - Include ground or taxi burn and trip fuel burn. - Switch between Load, Sheet and Envelope views. - Review basic empty weight, station arms and moments. - See which checks apply when a phase weight maximum is unknown. - Save loading snapshots alongside your other flight records. Templates are starting points. Verify the current aircraft's basic empty weight, station limits, fuel assumptions and CG envelope against its approved documents. AVIATION WEATHER AND AIRPORTS - Retrieve METAR and TAF reports from AviationWeather.gov. - Decode wind, visibility, clouds, altimeter and flight category. - Review TAF changes in a forecast timeline. - Decode pasted NOTAM and SNOWTAM reports. - Compare plain-language summaries with the original reports. - Find nearby airports and weather when you request location. - Search bundled airports by identifier, name, city or region. - Review available runways, elevation, frequencies and time zones. - Browse FAA reference material for preflight and study. TIME, DATES AND RECORDS - Work with flight time, duty snapshots and Zulu time. - Add or subtract times and dates. - Plan countdowns, work windows and business days. - Keep flight, duty, NavLog and Weight & Balance records. - Edit saved entries and browse activity in the Records Calendar. - Search records or duplicate a plan for the next trip. - Share supported results with Pilot Pro. Core calculators, bundled references and saved local data are useful offline. Live weather and App Store purchases need an internet connection. FREE STARTERS AND PILOT PRO E6B, E6B Simulator, Pilot Time, Flight Duty Snapshot and Time Speed Distance are free starters. Free iPhone and iPad access also includes three Pro calculator sessions and three Weight & Balance sessions per day, with five combined. Free Records allow one new record per day and six total. Pilot Pro removes those limits and enables sharing, with monthly and lifetime options. Temporary promotional access is separate from a purchase. Use Flight Calcs for planning and cross-checks.
