Easterly Definition & Meaning - Merriam-Webster

WebThe method for correcting for declination is as follows: 1. For Easterly Declination, subtract the declination from the true reading to obtain the magnetic reading. Magnetic = true - easterly declination 2. For Westerly Declination, add the declination to the true reading to obtain the magnetic reading. Magnetic = true + westerly declination WebFigure 1 — At (A), the absolute value of a westward declination must be added to the heading shown by the needle (colloquially known as red Fred) to determine true north; at …
