The Professional E6B with a simple interface that is very easy to use and provides all the calculations and conversions needed for flight planning. Enter wind details, required track (true or magnetic), distance and fuel consumption. Magnetic heading, ground speed, fuel requirement and weight are all instantly calculated.
A windrose screen is also included showing the wind effect for the 8 cardinal points.
Density altitude and runway wind components can be calculated as well as conversions from typical flying units. Preferred units (eg Knots, MPH, KPH, Liter, Gal, feet, Metre, lbs, Kg etc) can all be set and will be remembered.
