E6B Flight Computer The E6B flight computer is a type of slide rule that pilots and navigators traditionally use for performing a variety of calculations. Ih our E6B, we will compute wind correction angle and ground speed Wind correction angle is the angle that must be added to the desired course heading to offset the effect of a wind on the aircraft. Without such a correction, the aircraft would be flying an incorrect course. Delta-a is the wind correction angle in the following formula Aa sin twis the wind direction in radians. is the desired course in radians Va is the true airspeed in knots Vu is the wind speed in knots. The programmer user of the E6B class will instantiate the E6B object with the above data, but will use degrees for w and d, instead of radians. Java's Math class has tobegrees O and toRadians (0 methods. The result will come out in radians, but make your method return the delta-a in degrees. Suggested method header: public double windcorrectionAngle (i Ground speed is the true airspeed (TAS) corrected for winds aloft. The following formula computes ground speed: desired course is d ground speed is Vg heading correction angle is delta-a true airspeed is Va wind direction is to wind speed is Vu d, a and w are angles entered by the user in degrees. Java's Math class methods assume radians. vg, Va and Vv are consistent units of speed (usually knots). Suggested method header public double groundSpeed
