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. 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, weight and balance, 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. The included Apple Watch app runs natively on the watch (no iPhone required after it's installed) and includes the same 22 functions and 18 conversions as the iPhone/iPad app. 22 AVIATION FUNCTIONS -Pressure & Density Altitude -Planned True Airspeed -Heading and Groundspeed -Leg Time -Fuel Required -Crosswind, Headwind and Tailwind -Cloud Base -Actual True Airspeed -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) -Required Rate of Climb -Specific Range -Top of Descent -Required Rate of Descent WEIGHT & BALANCE CALCULATOR The new weight & balance calculator makes computing aircraft loading problems a breeze. The app allows you to create and store multiple aircraft profiles, and then quickly edit the various weights and arms for quick calculations. After adding the weight of your pilot and passengers, fuel and baggage, you’ll instantly see your takeoff weight and center of gravity (CG). It’ll also compute zero fuel weight and landing weight, and shows an instant analysis to to verify that you’re within limits. 18 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 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.
