An E6B flight computer and a complete Weight & Balance, in one app — the two tools a pilot actually reaches for before every flight, without a subscription. Built from the reviews of every other E6B on the store: the calculations they got wrong, the units they wouldn't accept, and the features that got taken away. Free - Time / Speed / Distance - Fuel required, flow, and endurance - Unit converter - distance, speed, pressure, temperature, fuel weight Pro - one purchase, forever - Weight & Balance - add and rename your own stations, save profiles for every aircraft you fly, CG envelope graph, takeoff and landing (after fuel burn) plotted together, %MAC, lb-in or kg-m - Pressure, density, and true (cold-corrected) altitude - CAS to TAS, EAS, Mach and speed of sound - Wind triangle, unknown wind, crosswind and headwind (with gust), true to magnetic to compass heading, off-course correction - Top of descent, required descent and climb rate, glide distance - Holding entry with wind correction, rate and radius of turn - Performance-table interpolation - Cloud base and freezing level - Export your W&B sheet to PDF What sets it apart - Weight & Balance done in full - not removed in an update, not sold as a separate app - Decimals and negative numbers everywhere - 62.07, 30.02, -13, all accepted, on a keypad built for the app so the system keyboard never gets in the way - Real international units - inHg, hPa, mb, mmHg, kg, lb, litres, US and Imperial gallons, metres, feet, degrees C, degrees F, K - shown right next to every value - Your last inputs carry over between calculators, so pressure altitude flows into density altitude flows into TAS - Tap "How was this calculated?" on any result to see the formula and its source - Works 100% offline - in the run-up area, the ramp, or with no signal - Dark mode for night flying, adjustable text size, screen stays awake One-time purchase The free calculators are fully working - never crippled to push the upgrade. One purchase unlocks everything else. No subscription. No ads. No features taken away later.
