WebAug 25, 2000 · When only one known object is visible and you can't get both a range and bearing to it, you can take bearings to it at different times to obtain a running fix. This is … WebAug 25, 2000 · When only one known object is visible and you can't get both a range and bearing to it, you can take bearings to it at different times to obtain a running fix. This is the procedure: Take the first bearing and note the time and log reading, if available; plot the position line on the chart and mark it with its direction and the time.

However, it also must be noted that the bearing of a …
WebUsually, a fix is where two or more position lines intersect at any given time. If three position lines can be obtained, the resulting "cocked hat", where the three lines do not intersect at the same point, but create a triangle, gives … WebThe bearing angle value will always be less than 90 degrees. [1] For example, if Point B is located exactly southeast of Point A, the bearing from Point A to Point B is "S 45° E". [3] For example, if the bearing between Point A and Point B is S 45° E, the azimuth between Point A and Point B is 135°. [1] [3] Azimuths and bearings. Types [ edit]
