Math at work · aviation, worked out

The Flight Computer

The math on a pilot’s E6B, one step at a time: wind correction and ground speed, crosswind components, time, distance and fuel, pressure and density altitude, true airspeed, true to magnetic to compass, top of descent, weight and balance, turns and glide. The trig behind the wind triangle is on the Unit Circle, plain unit changes on the Measuring Tape.
