PilotCalc Pro

PilotCalc Pro is a fast, offline-first flight calculator built by a pilot, for pilots. 22 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 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 FASTER WEATHER INPUT Paste a raw METAR into the weather calculators to auto-fill the inputs — no manual transcription. PRIVACY No accounts. No ads. No tracking. No third-party analytics. Your data stays on your device and syncs only through your own private iCloud. 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.
