E6B Flight Calculator

E6B Flight Calculator turns your iPhone into a dedicated flight computer: a backlit LCD, real keys and a big ENTER key. Pick a function, type your numbers and read the answer. When a picture helps, the LCD draws it.

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 • US or metric units, and avgas or Jet-A fuel weights CALCULATOR AND TIMERS • A calculator that does time math: add up flight times in H:MM • Stopwatch and countdown, with live UTC and local clocks BUILT FOR PILOTS • Three backlights: DAY, BACKLIT and a dark amber NIGHT • Star your go-to functions in FAV • Works offline, with no account • Remembers every value, leg and setting E6B PRO Trip planning and weight & balance are part of E6B Pro, an in-app purchase. Everything else 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 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.
