E6B Flight Computer Calc vs E6B Flight Computer

Every E6B calculation. Free. Offline. This does what the metal wheel in your flight bag does, without the wheel — free and offline. A KEYPAD BUILT FOR A COCKPIT Most aviation calculators hand you the system keyboard: small keys, half the form covered, a minus sign that fights you. This one has its own — big keys you can hit in turbulence, and it never rearranges what you already typed. YOUR UNITS, EVERYWHERE Altimeter setting in hPa or inHg. Speed in kt, km/h or mph. Distance in nm, km or sm. Temperature in °C or °F. Fuel in litres, US or imperial gallons. Set them once: every screen, widget and saved calculation follows, input fields included. Outside the US the app starts in hPa and litres. A converter screen adds fuel volume to weight for avgas, Jet A and mogas. FLIGHT • True airspeed: IAS to CAS to TAS and Mach, using real compressible-flow relations • Pressure altitude, density altitude and temperature-corrected true altitude • Wind triangle: true heading, wind correction angle, ground speed • Crosswind and headwind for a runway, with gusts and your demonstrated limit • Time, speed and distance — fill in any two, get the third • Fuel: burn rate, endurance, required, reserve, point of no return, equal time point • Climb and descent: rate, gradient, angle, top of descent, obstacle clearance • Turn: rate, radius, bank for standard rate, load factor, stall speed in the turn • Cloud base, freezing level and glide range • Great circle distance and initial course, true to magnetic to compass • Holding entry: direct, parallel or teardrop, and the heading to fly WEIGHT AND BALANCE Build a profile from your own aircraft's weighing report — empty weight, arms, station limits, CG envelope. Load it, and see the point plotted inside the envelope, not just a number. Tanks are loaded in gallons or litres and weighed by fuel type. No aircraft library is bundled, because two airframes off the same line do not weigh the same. CLOCKS, TIMERS AND THE SUN Zulu, local and departure-field time side by side. Flight timer that runs on the Lock Screen. Countdown with holding-leg presets. Sunrise, sunset and civil twilight for any coordinate — and the three different moments night, position lights and night currency begin. ON EVERY DEVICE YOU FLY WITH iPhone, iPad, Apple Watch and Mac. The Watch app calculates on its own — crosswind and density altitude on your wrist. Saved calculations sync over iCloud. WIDGETS Crosswind on your home runway, a Zulu clock, and density altitude at your field, on the Home Screen and the Lock Screen. FOR STUDENT PILOTS The calculations the written test expects, with the inputs and the workings on the same screen so you can see where a number came from. Exam mode hides saved history and anything that reaches the network with one switch, and leaves every calculation in place. METAR AND TAF, DECODED Paste a raw observation or forecast and read it in plain language: wind, visibility, ceiling and the flight category. The same report then feeds the calculations — its altimeter and temperature give density altitude at your field, its wind gives the crosswind on your runway. Offline, no account. CHECKED, NOT ASSUMED Every formula is verified against published references — the ICAO standard atmosphere, the FAA density altitude chart, the AIM holding sectors — and re-checked automatically on every change. FREE, AND WHAT ISN'T Every calculation and conversion: free, unlimited, forever. The one-time unlock adds unlimited METAR/TAF decoding, the analog wheel, exam mode, unlimited aircraft, unlimited history and the widgets — each free to try first. One payment, never a subscription. No ads, ever: nobody should watch a rewarded video in a cockpit. Planning aid only. Not for primary navigation. Always cross-check against your POH, your charts and your own arithmetic.

Crabwise is an E6B flight computer for iPhone, built for student pilots, private pilots and CFIs who want the answer and the working behind it. WIND TRIANGLE (FREE) • Find heading: enter TAS, true course and the wind to get wind correction angle, true heading and ground speed • Find wind: enter heading, TAS, track made good and ground speed to back out the wind you actually flew in • A live vector diagram shows the air, wind and ground legs of the triangle UNIT CONVERSION (FREE) Nautical miles, statute miles and kilometers; knots, mph and km/h; pounds and kilograms; US gallons and liters; °C and °F; inHg and hPa; feet and meters. Fuel weight for avgas (6.0 lb/US gal) and Jet-A (6.7 lb/US gal). CROSSWIND BEFORE YOU LAND Enter the runway number and the tower or ATIS wind. Crabwise shows the crosswind from the left or right, the headwind or tailwind, and the components in gusts. ALTITUDE AND AIRSPEED Pressure altitude from field elevation and altimeter setting, the way the FAA knowledge test expects it. Density altitude from the full ISA density ratio, not the 120 ft per degree rule of thumb. True airspeed from calibrated airspeed with compressible flow, and Mach number. TIME, SPEED, DISTANCE AND FUEL Solve for whichever one is missing. Fuel burn, fuel flow, endurance, and total required fuel with taxi, run-up and reserve. Use gallons, liters or pounds. WEIGHT AND BALANCE Add stations with weight and arm, get moments, total weight and center of gravity. Enter the corner points of the CG envelope from your POH and see at once whether you are inside it. SEE EVERY STEP Each result can open into the formula and the numbers substituted into it, the way you would work it on a paper E6B. Useful for the written exam, the oral and the checkride. PRIVATE AND OFFLINE Every calculation runs on your iPhone. No account, no ads, no tracking, and no signal needed. Light and dark themes. FREE AND PRO Free: wind triangle (find heading and find wind) and unit conversion. Pro: crosswind, time-speed-distance, fuel, altitude and airspeed, weight and balance, and step-by-step solutions for every calculator. Crabwise Pro is available weekly, monthly or yearly, or as a one-time lifetime purchase. The yearly plan starts with a 3-day free trial. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before that. Manage or cancel them in your App Store account settings. The lifetime purchase is a single payment and does not renew. Not for navigation. Crabwise is for training and reference only. Always cross-check with your POH, approved charts and official sources. Crabwise is not affiliated with or endorsed by the FAA.
