E6B Flight Computer CFI Pilot vs E6B Flight Computer + W&B

E6B Flight Computer is the essential aviation calculator for student pilots, CFIs, and cockpit professionals. Built for PPL checkrides, cross country planning, and everyday flight operations — all offline, no internet required. AVIATION CALCULATORS 22 precision calculators covering every phase of flight: Wind & Navigation — Wind correction angle, heading & ground speed, crosswind & headwind components, course & distance between coordinates. Speed & Altitude — True airspeed (TAS), calibrated airspeed (CAS), density altitude, pressure altitude, true altitude, and cloud base estimation using ICAO standard atmosphere formulas. Fuel — Fuel required, endurance, point of no return, and equivalent still air distance. Performance — Weight & Balance with interactive CG envelope chart, top of descent, climb/descent gradient, and percent MAC. Time — Leg time, ETA calculator, and time/speed/distance solver. WEIGHT & BALANCE WITH ENVELOPE CHART Add crew, passengers, fuel, and baggage. The app computes total weight, total moment, and CG position — and plots it live on an interactive envelope chart. The tool every CFI recommends. UNIT CONVERSIONS 9 bidirectional converters: Temperature, Distance (NM/SM/KM), Speed (kt/mph/kph), Altitude (ft/m), Pressure (inHg/hPa), Weight (lb/kg), Volume (gal/L), Avgas weight, and Jet-A weight. COCKPIT CLOCKS & TIMERS Three simultaneous clocks — Zulu (UTC), Local, and Home timezone. Countdown timer with alarm, stopwatch with lap times for leg tracking. HOME SCREEN WIDGETS - Zulu Clock widget — always-on UTC time - Density Altitude widget — current conditions at a glance - Quick Converter widget LIVE ACTIVITY Flight timer countdown on your Lock Screen and Dynamic Island — no unlock needed. WORKS COMPLETELY OFFLINE No internet, no account, no server. Every formula runs on-device using pure ICAO Standard Atmosphere calculations.

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. Calculations use the ICAO standard atmosphere and established aviation formulas, and are verified against published handbook examples. This app is a training and planning aid. Use your POH/AFM and official sources for flight decisions.
