E6B Aviation Calculator: GoFly
Flight Computer for Pilots
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Fast, accurate, and built to feel good in your hands.
No more spinning a plastic wheel and hoping. Type your numbers, get a precise answer, and tap once to see exactly how it got there. Every mode is dialed in and easy to use, whether you're planning a cross-country or just checking a crosswind before you taxi.
Live Wind Triangle
- A cockpit-style instrument that redraws heading, track, and wind as you type
- View the crab angle, not just the number for it
Show the Work
- Every result opens up into the formula and the values you plugged in
- Expand it when you want to understand it, collapse it when you don't
Core E6B Tools
- True airspeed and density altitude
- Time, speed, distance
- Fuel and endurance
- Crosswind components
- Unit conversions
METAR Decoder
- Pull any airport's live report from the NOAA Aviation Weather Center
- Read it in plain language, line by line
Weight & Balance
- Load your aircraft and see gross weight and CG on the envelope
- Save airplanes as presets so you're not re-entering them
The Small Stuff
- A keypad with the units right on each field, so knots never get mixed up with mph
- Works offline. Every calculation runs on your phone. Only live METARs need a signal.
- No accounts, no analytics, no ads, nothing collected. Your numbers stay on your phone.
