... from magnetic north. This involves a “correction” (the Navy calls it “uncorrecting
”) for magnetic variation. Selecting the isogonic line nearest his point of
measurement, the pilot observes the value given and adds this value if labeled W

Handbook on Radiation Probing, Gauging, Imaging and ...
Therefore, each radiation energy measured by the detector defines an isogonic
line within the object. The intensity of the scattered radiation can then be
determined by integrating the scattering from all points along the corresponding
isogonic ...

Consequently the amount of variation as indicated against any isogonic line on a
chart will be correct only at the date on which the chart was drawn. The amount of
change, however, is very small and is reasonably consistent, so the method ...

Instrument Flying Handbook: Revised Edition
To fly a true course of 180° there, the pilot would have to subtract the variation
and fly a with the heading of the aircraft; it is the same anywhere along the
isogonic line. Deviation The magnets ina compass alignwith any magnetic field.
