Description
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
