FlyBy E6B is an essential application for all pilots. Designed by a professional airline pilot it includes many features not found in the "other" E6B programs. If you are considering a career in aviation FlyBy E6B has functions that you can use in every aircraft you will fly. FlyBy E6B was one of the very first applications of its kind published for the Palm Pilot. Used by thousands of pilots the world over, it has evolved from the suggestions and feedback we have received. Please visit our web site for more detail and screen shots. FlyBy E6B Features (70+): Airspeed Calculations: - True Airspeed using Calibrated Airspeed - True Airspeed using Mach# - Calibrated Airspeed using TAS - IAS Using MACH# - Equivalent Airspeed using CAS - Mach# Using TAS - Mach Crossover Altitude - Planned MACH# - Planned TAS - Vref CAS Wind Calculation: - Find Wind Direction and Speed - Find Wind Component (headwind and crosswind) Heading and Ground Speed: - Find Heading, Ground Speed, ETE and Fuel Burned Time-Speed-Distance: - Find Estimated Time Enroute - Find Ground Speed - Find Distance - Find Fuel Time - Find Fuel Flow - Find Fuel Burned - Find Estimated Time of Arrival - Journey Log Time - Time Adder - Fixed GroundSpeed (Find a True Airspeed given a track, wind and required groundspeed) - Crew Rest Altitude Calculations: - Density Altitude - Pressure Altitude - True Altitude - Cold Temperature Altitude Correction - China RVSM Airspace - Device Altitude (If device has pressure sensor) Vertical Navigation Calculations: - Distance and Time using Altitude Change, Ground Speed, Vertical Speed - Rate of Descent using Altitude Change, Ground Speed, Distance - Rate of Descent using Altitude Change, Ground Speed, Descent Angle - Feet/Nm using Vertical Speed, Ground Speed - Feet/Nm (%) using Gradient %, Ground Speed - Rate of Climb using Required Climb Gradient and Ground Speed - SCDA (Constant Descent Angle) - VDP (Visual Descent Point) - VPA Deviation (Vertical Path Angle Deviation) Navigation Calculations: - Critical Point - Equal Time Point - Point of No Return - Time to Minimum Descent Altitude - Track and Distance between two points with map plotting of the great circle track.
