Based on Sporty’s popular handheld E6B Electronic Flight Computer, the E6B app has been designed from the ground up to make the most of iOS on the iPhone, iPad and Apple Watch, and MacOS on Apple Computers. The software is based on the tried and true formulas and algorithms developed over the years by Sporty’s team of over 50 pilots. Its pilot-friendly design makes quick work of any navigational, conversion or fuel problem and it also performs conventional arithmetic calculations. The advanced timer/clock feature simultaneously tracks Zulu, Local and Home time zones. The timer counts either up or down, and will display an alert when reaching zero. 27 AVIATION FUNCTIONS -Pressure & Density Altitude -Planned True Airspeed -Heading and Groundspeed -Compass Heading -Leg Time -Fuel Required -Crosswind, Headwind and Tailwind -Cloud Base and Freezing Level -Actual True Airspeed -Actual True Altitude -Wind Speed and Direction -Groundspeed -Planned Mach Number -Required True Airspeed -Required Calibrated Airspeed -Distance Flown -Endurance -Fuel per Hour -Actual Mach Number -Percent Mean Aerodynamic Chord (MAC) -Hydroplane Speed -Required Rate of Climb -Specific Range -Pivotal Altitude -Top of Descent -Required Rate of Descent -Glide Distance 22 AVIATION CONVERSIONS -Celsius :: Fahrenheit -Nautical Miles :: Statute Miles -Nautical Miles :: Kilometers -Feet :: Meters -Pounds :: Kilograms -Avgas Gallons :: Pounds -Jet A Gallons :: Pounds -Gallons :: Liters -Hours/Minutes/Seconds :: Hours -Climb FT/NM :: Climb Percent -Climb FT/NM :: Climb Degrees CALCULATOR -Perform basic math without having to exit the application CLOCK/TIMER -Simultaneous tracking of Zulu, Home and Local time zones -Advanced timer counts up or down and operates independently so you can perform other calculations while the timer is running -Upon reaching zero in the countdown mode, a message will display no matter what app is active – a useful feature for missed approaches, switching fuel tanks, etc.

EF1 E6B is a complete electronic flight computer built for student pilots, CFIs, and certificated pilots who want a fast, offline, modern E6B without the bloat. EVERYTHING AN E6B DOES - FASTER • Wind triangle (heading, ground speed, wind correction) • True / calibrated / equivalent airspeed • Density and pressure altitude • Time / speed / distance • Fuel burn, endurance, and range • Standard atmosphere + lapse rate • Compass + magnetic heading with deviation and variation • Reciprocal headings, pivotal altitude, standard rate turns • Off-course (1-in-60) corrections • Climb / descent rates and ground distance • Cloud base, glide distance, holding pattern entry • Linear interpolation • Universal converter (length, mass, volume, speed, temp, pressure) CROSS-COUNTRY PLANNING Build a full multi-leg route with up to 20 checkpoints. Set true course, distance, wind, TAS, fuel rate, MSA, and frequencies for each leg. Drag to reorder, duplicate, or reverse the route in one tap. Choose VFR or IFR mode and the app applies the correct FAR fuel rules: • VFR: 30-min day or 45-min night reserve, optional alternate • IFR: 45-min reserve, alternate-required toggle, alternate fuel auto-computed from distance to alternate Trip totals show ETE, ETA, fuel legality (LEGAL or NOT LEGAL with margin), and per-leg fuel remaining. PRINTABLE NAV LOG Generate a clean PDF nav log — VFR or IFR titled — with every checkpoint, fuel breakdown, frequencies card, and a side panel showing usable fuel, taxi, climb, enroute, alternate, and reserve. Email, print, or save it. FLY THE CROSS-COUNTRY Tap START FLIGHT, then mark off each checkpoint as you pass it. The app records actual time enroute, actual ground speed, and ATA, then writes them back into your post-flight log automatically. WEIGHT & BALANCE Build aircraft profiles, enter station moments, and check CG against the envelope. DESIGNED FOR PILOTS • Works fully offline - no signal, no problem • Optimized for iPhone and iPad with dark cockpit theme • Adjustable font scale for kneeboard readability • US or metric units, switch any time • Save unlimited routes • Backup and restore your data SUBSCRIPTION The EF1 E6B unlocks all features with a 7-day free trial, then $3.99/month or $19.99/year.
