Thank you for using Flight Calcs. Careful pilots like you deserve planning tools that respect your time, keep the important numbers readable, and make a solid cross-check easier. Flight Calcs brings aviation calculators, weather decoding, records, airport data, and time tools together for student pilots, private pilots, CFIs, aircraft owners, and working crews. PLAN WITH ONE PRACTICAL TOOLKIT: - Use a modern E6B calculator for wind correction, heading, groundspeed, time, distance, and fuel. - Work through the mechanical E6B simulator when you want a visual training aid. - Estimate fuel burn, endurance, trip fuel, and reserve fuel. - Calculate pressure altitude, density altitude, true airspeed, Mach, and speed of sound. - Build a NavLog with leg details, fuel planning, and route notes. - Convert aviation units for fuel, weight, distance, speed, pressure, temperature, and time. WEIGHT AND BALANCE THAT SHOWS THE WORK: - Enter passenger, baggage, and usable fuel loads by station. - Review zero-fuel, ramp, takeoff, and landing phases. - See weight, arm, moment, CG range, and configured limit status. - Compare the Load, audit-friendly Sheet, and visual Envelope views. - Save the calculation as a dedicated record for later review. WEATHER AND PROCEDURE SUPPORT: - Retrieve live METAR and TAF reports by ICAO code when a connection is available. - Read decoded wind, visibility, clouds, altimeter, flight category, and forecast periods. - Decode pasted METAR, TAF, NOTAM, and SNOWTAM text. - Keep the latest live weather result available for review. - Use plain-language summaries while keeping the original report visible. RECORDS THAT STAY USEFUL: - Save flight records, duty snapshots, NavLog plans, and Weight & Balance calculations. - Let editors autosave after you pause, with clear saving and saved feedback. - Search, review, edit, duplicate, share, and delete supported record types. - Browse saved activity by date in Calendar. - Share clearly labeled inputs and calculated results. - Use an adaptive list and detail workspace on iPad with compact navigation on iPhone. OFFLINE REFERENCE MATERIAL: - Search more than 72,000 bundled airports by identifier, name, city, country, or region. - Review runway, elevation, time zone, coordinate, and communication details. - Browse bundled FAA AIM reference topics for weather, altimetry, navigation, lighting, and preflight planning. - Keep core calculators, saved records, and bundled references useful without a network connection. MADE FOR THE WAY PILOTS LEARN AND PLAN: - Student pilots can compare manual E6B work with a clean digital result. - CFIs can load believable samples and explain each input and output. - Private pilots can rerun wind, fuel, loading, and performance scenarios quickly. - Aircraft owners can keep recurring planning records organized. - Working pilots can review block time, duty periods, schedules, and date math. The E6B Calculator, E6B Simulator, Pilot Time, Flight Duty Snapshot, and Time Speed Distance tools are free starters. Pilot Pro unlocks the remaining calculator catalog and removes free Records limits. Monthly and lifetime options are shown in the app with localized App Store pricing. Promotional access earned in the app is temporary and separate from a purchase. Flight Calcs is a planning and cross-check aid. Always confirm results with the current aircraft POH or AFM, approved weight and balance data, official weather, operator procedures, and applicable regulations before making an operational decision. PILOT PRO: Pilot Pro unlocks the full calculator library, sharing features, and expanded records tools. Pricing is shown in the app before purchase and may vary by region. Pilot Pro is available as a monthly auto-renewing subscription or a one-time lifetime purchase. Pricing is displayed in the app before purchase and may vary by region.
