PilotCalc Pro vs Aviation Weather Decoder

PilotCalc Pro is a fast, offline-first flight calculator built by a pilot, for pilots. 27 focused calculators across regulatory reference, core E6B, planning, and conversions — each designed for the cockpit: large, readable outputs, dual Zulu/local times where it matters, and a keypad that never blocks a decimal point or a minus sign. Everything works offline. No account, no ads, no tracking. REGULATORY • Max FDP — maximum flight duty period (GCAA; advisory) • Crew Rest — in-flight rest timing with an on-device rest timer • Converted Met Visibility — from reported visibility CORE • Pressure Altitude — indicated altitude + QNH → pressure altitude • Density Altitude — pressure altitude + OAT → density altitude • TAS / IAS / CAS / Mach — four-way airspeed solver • Wind Components — crosswind, headwind & drift PLANNING • Time · Speed · Distance — solve any of the three • Fuel — burn, endurance & required fuel • Fuel Uplift — refuel cross-check; USG ⇄ kg, uplift sum & discrepancy • Climb Gradient — gradient ⇄ rate of climb ⇄ ground speed • Descent — top of descent & crossing restrictions • Glide — engine-out glide range (still air) • Cloud Base — convective cloud base from temperature/dewpoint • Holding Pattern — entry, timing & geometry • Sun Events — sunrise, sunset & twilight • Sun En Route — sunrise/sunset along a route in flight • Weight & Balance — weight, CG & envelope • NEO Crosswind on Ground — A320/A321neo takeoff crosswind + tailwind envelope • Oceanic Crossing — North Atlantic & Pacific (PACOTS) oceanic tracks REFERENCE • Converter — length, speed, temperature, pressure, mass, volume • Metric Altitude — China/Russia metric levels → feet • RVR / Visibility — RVR & visibility (FAA ft ⇄ m) • Currency — offline currency converter • Cold Temp Correction — cold-day altitude correction (ICAO table) • WX Decode — read a METAR, TAF, D-ATIS or SNOWTAM in plain language • Dangerous Goods — decode a NOTOC drill code; look up a UN/ID number FASTER WEATHER INPUT Paste a raw METAR into the weather calculators — or scan printed weather text with the camera — to auto-fill the inputs. No manual transcription. PRIVACY No accounts. No ads. No tracking. No third-party analytics. No network. Your data never leaves your device. IMPORTANT — ADVISORY USE ONLY PilotCalc Pro is a planning and educational aid. Its outputs — including all regulatory figures such as flight-duty-time limits — are advisory and are not a substitute for official aeronautical information, approved aircraft documentation, your operator's Operations Manual, or current charts and NOTAMs. Always verify against authoritative sources. The pilot in command is solely responsible for all operational decisions.
