Variation: the angular difference between true north and magnetic north indicated on charts by isogonic lines (magenta dashed lines running north/south with degree indication)ĭetermine Magnetic Heading: true heading corrected for magnetic variation. Subtract on the left, add on the right to get true heading.Wind correction angle is read from the mark.Mark the velocity of the wind away from the grommet (center hole).Align the direction of the wind with the true index on the E6B. ![]() True Heading: true course corrected for wind Heading: the numerical degree the nose of the aircraft is pointingĬalculate Wind Correction Angle: aircraft heading needed to maintain straight ground track with winds aloft Ground track: the line the airplane is moving over the ground
