E6B Flight Calculator
Wind, Fuel, Weight & Balance
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Wind triangles, crosswind, density altitude, fuel and more, on a backlit LCD with real keys. Plan trips and check weight & balance with E6B Pro.
E6B Flight Calculator turns your iPhone, and now your Apple Watch, into a dedicated flight computer: real keys, a big ENTER key, and a display that draws the answer. Pick a function, type your numbers and read the result.
ON YOUR WRIST
- Every calculation from your iPhone on Apple Watch, with your timers and favorites up front
- Adjust wind, speed, fuel and more with the Digital Crown. The answer updates as you turn and syncs back to your iPhone
- A flight timer and countdown that keep counting in Always On, with a tap on your wrist when the countdown ends
- Works without your iPhone nearby, and changes sync both ways
- Complications for your watch face show your timers and latest results
WIDGETS
Home Screen and Lock Screen widgets show your latest calculations and timers. Tap one to open that page.
TWO LOOKS
- Classic LCD with three backlights: DAY, BACKLIT and a dark amber NIGHT
- Glass Cockpit: a dark avionics display with color-coded values, cyan for what you enter and magenta for what's computed
WHAT IT SOLVES
- Wind: heading and ground speed, crosswind and headwind for any runway, and finding the wind
- Altitude: pressure and density altitude, cloud base and the standard atmosphere
- Airspeed: true airspeed, required CAS and Mach number
- Time, speed and distance, including ETA
- Fuel: fuel burn, fuel flow and endurance
- Climb and descent: climb gradient, top of descent and required vertical speed
- Glide: glide distance, glide ratio and altitude required
- Heading: compass heading and reciprocals
- Navigation: rhumb line between two positions, and holding pattern entries
- 12 unit converters: distance, speed, duration, temperature, pressure, volume, fuel flow, weight, climb rate, gradient, torque and angle
SEE THE ANSWER
The wind over your track on a north-up compass card, the runway with the wind arrow, the holding pattern with its entry, and your CG inside the aircraft's envelope.
FEELS LIKE A REAL FLIGHT COMPUTER
- Mode keys for FLT, PLAN, W/B, CALC, TIMER, FAV and SET
- Every key press has a haptic click; a key that doesn't apply gets a firm buzz
- Type math right into a field, like 340+170 for two people up front
- Enter times as H:MM and positions as D:MM, and switch a value's units with CONV
- A calculator that does time math: add up flight times in H:MM
- US or metric units, and avgas or Jet-A fuel weights
- HOW TO USE in SET walks you through it, a topic a page
BUILT FOR PILOTS
- Star your go-to functions in FAV
- Works offline, with no account
- Remembers every value, leg and setting
