Kármán E6B

Your complete flight computer, redesigned for the modern cockpit.

Kármán E6B replaces your mechanical E6B flight computer, paper weight & balance sheets, and scattered aviation tools with one powerful app. Built for student pilots, private pilots, and professionals alike.

WIND & NAVIGATION Wind correction angle, true heading, ground speed, headwind/crosswind components, compass heading corrections, drift angle, off-course correction, and Vref gust correction. Everything you need from departure to final approach.

SPEED, TIME & DISTANCE Calculate time en route, distance traveled, ground speed required, average speed across legs, time to station, and estimated time of arrival.

FUEL PLANNING Fuel required, burn rate, fuel remaining, endurance, range, and fuel with reserves. Plan every leg with confidence.

ALTITUDE & ATMOSPHERE Pressure altitude, density altitude, true altitude, ISA deviation, temperature lapse rate, cold weather altitude correction, cloud base and freezing level estimates, and pivotal altitude for maneuvers.

AIRSPEED True airspeed (TAS), IAS corrections, calibrated airspeed approximation, and Mach number calculations.

CLIMB & DESCENT PLANNING Rate of climb/descent, time to climb, distance and fuel during climb, top of climb (TOC), and top of descent (TOD) planning.

IN-FLIGHT & EMERGENCY Holding pattern entry determination, diversion heading, revised ETA, fuel after delay, distance to alternate, time remaining with fuel, engine-out glide distance, and hydroplaning speed.

REAL-TIME WEATHER Look up METAR and TAF reports for any airport worldwide. View raw or decoded weather data. Find the nearest reporting airport using your location. Pull to refresh for the latest conditions.

WEIGHT & BALANCE Create aircraft profiles with custom loading stations. Calculate total weight, center of gravity, and moment in real time. Visualize your CG position on an interactive envelope chart. Save and load scenarios. Includes preset aircraft to get started immediately.

7 UNIT CONVERTERS Knots/MPH, nautical miles/statute miles, gallons/liters, pounds/kilograms, feet/meters, fuel weight/volume, and Celsius/Fahrenheit.
