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.
