One note provides instructions for converting magnetic azimuth to grid azimuth; the other, for converting grid azimuth to magnetic azimuth. Plotting an azimuth on the map. If they are equal, the protractor is correct. Photos courtesy of Army Study Guide, author, DOD.

A circle equals 6400 mils divided by 360 degrees, or 17.78 mils per degree. To calculate the new Grid Magnetic Angle (GMA), multiply the maps age in years by the annual change (AC) and subtract this from the maps old GMA (OLD). 124. This dot should be inside of your original grid square. Identify the map's starting point (A). Repeat 3, 4, and 5 for a second position and a third position, if desired. Step 1. When using the protractor, the base line is always oriented parallel to a north-south grid line. Determine the value of the angle (grid azimuth) from the scale. Figure 6-15. A protractor is a tool used to measure direction in degrees , from one point to another on a map . It is imperative that all of these skills and they are the basics of finding your way in the field, become second nature to all of the candidates who aspire to be in the. hbbd``b` @ b*? RecPak is a meal replacement for the outdoors that saves you weight, space and time in the most challenging environments, just add water. When the azimuth between two points on a map is desired, the points are joined by a straight line. However, where the intersection of the lines meet on the map is your location. Locate two known positions on the ground and mark them on your map (A, figure C-37). A rule to remember when solving such problems is this: Nomatter where the azimuth line points, the angle to it is always measured clockwise from the reference direction (base line). 69N4' >s)u]\[GZ+m1i+l,-b ;;5re vw,u@m(MOaUu`6'#43C^R"PFdI$L1-V.pke55l%|DduZ 8v8'U)~a~zK{Dnq[pc\d Using your pencil, make a small tick mark on the map at the edge of the protractor at the desired azimuth. Look down and read the azimuth from beneath the fixed black index line. A declination diagram is a part of the information in the lower margin on most larger maps. An arc indicated by a dashed line connects the prongs for true north and grid north. Hvg dKg|?s::ikP8> Align a protractor (left drawing) or the N-S or E-W directional axis of a compass (right drawing) with the map's border and read the bearing in degrees toward the direction of the destination. Determine the Grid Coordinates of a Point on a Military Map Measure Distance on a Map Convert Azimuths Determine Azimuths Using a Protractor Locate an Unknown Point on a Map and on the Ground by Resection Locate one's position on .
