Familiar to pilots the world over, the E6B Flight Computer is one of the few mechanical calculators / slide rules still in common use today. Designed in the 1930s by navigation pioneer Lt. Philip Dalton, the E6B has changed little over the last 9 decades and combines the ability to quickly and accurately perform speed, time, distance, fuel burn, altitude/speed correction, wind drift and other calculations in a single compact package that requires no batteries.
