E6B vs E6B Flight Calculator

E6B is a modern flight computer for iPhone and iPad — built for student E6B is a modern flight computer for iPhone and iPad — built for student pilots, instrument candidates, and working aviators who need fast, accurate calculations without fumbling with a physical whiz wheel. WEATHER • Pressure & Density Altitude — from baro setting, OAT, and field elevation • Crosswind, Headwind & Tailwind — enter wind speed, direction, and runway heading • Cloud Base & Freezing Level — AGL and pressure altitude • Hydroplane Speed PREFLIGHT • Planned True Airspeed — from CAS, pressure altitude, and OAT • Required CAS / Required TAS — reverse-solve airspeed equations • Heading & Groundspeed — full wind triangle solution • Compass Heading — with magnetic variation and compass deviation • Leg Time — solve any one of time, speed, or distance • Fuel Required & Endurance • Planned Mach Number • Time Math — add and subtract times in HH:MM:SS IN-FLIGHT • Actual True Airspeed — from CAS, altitude, and OAT • Actual True Altitude — corrected for non-standard temperature • Groundspeed — from elapsed time and distance • Fuel Per Hour — from fuel used and elapsed time • Distance Flown WEIGHT & BALANCE Build custom aircraft profiles with stations, limits, and CG envelopes. Load passengers, fuel, and cargo — E6B calculates total weight, moment, and CG in real time. Save multiple profiles for different aircraft. CONVERSIONS Bidirectional converters for: NM ↔ SM ↔ km, feet ↔ meters, °C ↔ °F, inHg ↔ mb, lbs ↔ kg, US gallons ↔ liters, HH:MM:SS ↔ decimal hours, Avgas and Jet A weight (gallons or liters to pounds), and minimum climb gradient to percent or degrees.

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 E6B PRO Trip planning, weight & balance and the timers are part of E6B Pro, an in-app purchase. Everything else, on iPhone and Apple Watch, is free. - PLAN: legs with distance and course; magnetic heading, ground speed, time and fuel for each leg; trip totals with ETA and fuel with reserve - W/B: your aircraft's profile and CG envelope, load and CG check, weight shift and % MAC - TIMER: a flight timer (stopwatch) and countdown with live UTC and local clocks, on iPhone and Apple Watch, and in widgets and complications E6B Pro is a one-time Lifetime purchase, or a monthly or yearly subscription that starts with a 7-day free trial for eligible new subscribers. Payment is charged to your Apple Account when you confirm the purchase or, with a free trial, when the trial ends. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and renewal is charged within the 24 hours before the period ends. Manage or cancel anytime in your Apple Account settings.
