The E6B also has the nickname the “Whiz Wheel”. The E6B has mostly been replaced with on board electronic flight computers, but is still used for flight training or as a backup. With the E6B, a pilot can do many flight planning calculations. These include: wind correction, fuel burn, time and distance, and ground speed. The E-6B was invented in the late 1930's by Navy Lt. Philip Dalton and became very popular for military and airline use.
