The E6BJA Flight Computer is a powerful software-based digital computer for practising performing aeronautical and flight calculations speedily and easily. Inspired by the Whiz-wheel (e.g. E6B, CR-1, CRP-1, CRP-5 etc), an ingenious and excellent teaching tool, and designed to replace handheld electronic digital flight computers (e.g. CX-3), the E6BJA software app is rich in features, powerful and efficient. It can be installed on a phone or tablet --- for convenience --- and has a number of advantages over the whiz-wheel; calculations are simpler and quicker to perform, with less margin of error, better reproducibility and is less error-prone. It has a clear and intuitive user interface. The E6BJA calculator currently provides the following features: E6BJA Wind, GS,TAS Visualiser and Diversions Star Holding Pattern Visualiser/Computer Wind triangle, True Air Speed, Ground Speed Visualiser Wind Triangle solver Wind Correction Angle Descent Calculator Fuel Calculator Equivalent Time Point (ETP) and Point of No Return (PNR). Weight, Arm and Moment Calculator Pressure Altitude Density Altitude Cloud Base Dew Point and Relative Humidity ISA 1976 Atmosphere Mach Number True Air Speed (TAS) to Indicated Air Speed (IAS) Indicated Air Speed (IAS) from True Air Speed (TAS) Ground Speed (GS) Load Factor from Bank Angle Turns Calculator Aviation Units Converter Weight and Balance Calculators for the following aircraft: Beechcraft V35 Bonanza Beechcraft BE76 Duchess Cessna 150M (1977) Commuter Cessna 152 (1979/1980) Cessna 170B Cessna 172M (1976) Skyhawk Cessna 172S (1998) Skyhawk Cessna 177B Cardinal Cessna 180 Skywagon Cessna 185D Skywagon Cessna 210M Centurion Cessna 421 Golden Eagle Diamond DA-20 Diamond DA-42 Cirrus SR22 Piper PA28-151 Warrior Piper PA28-161 Warrior II (1977/1978) Piper PA28-180 Archer Piper PA28R-180 Cherokee Piper PA32R-301 Saratoga Piper PA-34-200 Seneca Piper PA-44 Seminole Piper PA46-310P Malibu Robin HR100/210 Robin HR200/120 Socata TB9 Tampico Socata TB200 Tobago
