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. Your aircraft's current POH or AFM, approved Weight & Balance report, official weather briefing, operator procedures and applicable regulations remain the authority. For monthly subscriptions: Monthly Pro is a 1-month auto-renewable subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Read full description

Aviation Calculator puts everyday flight calculations behind dedicated keys, with the feel of a familiar pocket calculator. Designed for student and private pilots, it brings wind, navigation, fuel and performance calculations together. FLIGHT KEYS AT YOUR FINGERTIPS Calculate crosswind and gust components, wind correction, heading, groundspeed, time en route, fuel requirements and density altitude. Explore the function library, weight-and-balance tools and unit converter. PILOT TOOLS Save aircraft profiles and enter loading stations and CG envelope data from your aircraft documentation. Explore direct, parallel and teardrop holding entries with colored sectors and an animated aircraft. Check Zulu/UTC and local clocks, use a stopwatch or countdown, and calculate durations. BEYOND THE BASICS Plan a descent, convert climb gradients, explore turn performance, estimate still-air glide range, find a point of no return or equal-time point, and interpolate between chart values. UNDERSTAND THE RESULT See units beside inputs. Load clearly marked examples. Read formulas, sources and assumptions. Invalid or impossible inputs produce an explanation. YOUR PREFERRED UNITS Choose knots or miles per hour, US gallons or liters, and 0–6 decimal places in Settings. Display precision does not round the underlying calculation values. YOUR WORK, ON YOUR DEVICE Pin favorite functions and revisit saved calculations. Use Siri and Shortcuts for time en route, fuel required, crosswind, density altitude and top of descent with active access. BUILT FOR iPHONE, iPAD AND MAC Calculator keys adapt to compact displays. A wide window keeps the function library beside your work. Calculations work offline during your trial or after unlocking. No developer account, advertising or tracking. 30 DAYS FREE. THEN $9.99 ONCE. Activate the free 30-day Trial with Apple to try all features. After 30 days, a one-time US $9.99 purchase is required to continue calculating. Local App Store pricing may vary. No subscription. No automatic charge. Saved results stay readable. Internet is needed to activate, purchase or restore; use the same Apple Account to restore access. Aviation Calculator is a planning and training aid. Verify results using approved aircraft documents and current conditions. Approximate calculations and diagrams are labeled. Aircraft performance charts, approved CG envelope data, live weather and regulatory decisions are not supplied.
