WebFor easterly declinations, a negative sign is shown. For western declinations, a plus sign is shown. These signs indicate how to convert from the true bearing shown on the map to the compass bearing that you would need to follow. For example, in Boulder, Colorado, in 2004, the declination is 10.4 deg East. WebEasterly declinations are represented as positive values, and Westerly declinations are represented as negative values. For example, your current location could be represented …

The Difference Between True and Magnetic Heading

WebIf the declination that you are working with is a westerly declination then the new value will be a higher one (add the change), if it is an easterly declination the new value will be lower (subtract the change), or if your declination was 1 degree east you may now have a westerly declination. WebWhen converting true to magnetic heading, you’d do the opposite and subtract an Easterly, or add a Westerly, magnetic variation. This is where the saying East is least, West is best stems from. The PHAK gives an example of variation: Flying in the Washington, D.C., area, for example, the variation is 10° west. first united presbyterian church loveland co

A three … WebApr 5, 2024 · The word CADET reminds us that if we are making an alteration from a compass heading to a true heading, we add easterly variation. From Compass to True Add East: So we are going to add an Easterly variation to get back to true north. Consequently, it makes logical sense that we would subtract a Westerly variation to get back to true north.
