Consider the order and technique of driving in azimuths as an example of movement along the route from the northern outskirts of the village of Nikitsky to the bridge on the railway southeast of Zgarev. The data for azimuth movement on this route is shown in the diagram below.
The order and technique of driving in azimuths alone and in a group, maintaining the direction of movement along the alignment and when avoiding obstacles.
At the starting point (landmark 1 – Nikitsky) we set the pointer of the fly compass on the scale of 12 degrees – the magnetic azimuth to landmark 2 (barrow). Having released the brake of the magnetic needle and giving the compass a horizontal position, we orient it. Without knocking down the compass orientation, we sight (look) through the slot and the front sight from ourselves and see the mound. It stands out over local items. We walk 800 pairs of steps and exit to the mound.
At landmark number 2, we set the fly pointer to a new magnetic azimuth from the barrow to the ford (crossing the river) – 317 degrees. Orienting the compass, we determine the direction to reference point 3 from this magnetic azimuth. We notice an intermediate reference point in this direction, on which we begin to move. Having reached it, we again determine the direction of movement to landmark 3 in the same azimuth – 317 degrees, as at point 2.
Having come to the landmark (ford across the river) 3, we repeat the same actions as for landmarks 1 and 2, In the area from landmark 3 to 4 (pit), the direction of movement coincides with the direction of the clearing. Obviously, in this case there is no need to navigate around the compass and choose intermediate landmarks. Moving along the clearing, you only need to count pairs of steps so that, having come to the end of the clearing, you can calculate how much more remains to go to the pit – landmark 4.
In the area from landmark 4 to landmark 5, maintaining a given direction is facilitated by the fact that the path lies along the shore of the lake. Therefore, there is also no need to choose intermediate landmarks, but only from time to time it is necessary to check the compass direction and measure the distance traveled.
When moving in sections between landmarks 5, 6 and 7, the path passes through a continuous forest. This will make it difficult to orient and maintain a given direction of movement. To avoid mistakes in orientation and not to go astray, you must keep the direction of movement along the compass, keeping it in front of you all the time.
The order and technique of movement in azimuths by a group, maintaining the direction of movement along the alignment.
If the movement is performed by a group, then part of the group monitors the correct movement but the given azimuth along the compass. And the second part of the group will calculate the distance traveled. When driving in azimuth in an open, but poor, landmarks, the direction can be maintained along the alignment.
To do this, having determined the direction of movement along the compass, along the path behind you at certain intervals leave any signs (a stone, a stake hammered into the ground, a milestone, etc.). Moving forward, from time to time they look back and see that the direction of movement coincides with a straight line. Mentally drawn through the signs left behind. When moving on a snowy field, the directional signs can replace the track of its own movement (tracks of tracks, wheels, tracks).
The order and technique of movement in azimuth when avoiding obstacles.
If there is any obstacle on the way when moving along azimuths in an open area, then it is bypassed as follows. They notice a landmark on the opposite side of the obstacle in the direction of travel. Determine the distance to it and add it to the distance traveled. After that, bypassing the obstacle (if it is large, then use the compass), they approach the chosen landmark. Then, having determined by the compass the direction of the interrupted path, continue driving.
So, we examined the technique and the order of movement in azimuths. Of course, in practice, other skills are developed that can be useful in choosing the right direction of movement. It must be remembered that even under favorable conditions (a working compass, the absence of anomalies, careful accounting of declination, accurate calculation of pairs of steps, etc.) it is impossible to arrive exactly at the indicated place.
The fact is that, for example, the accuracy of the Adrianov compass is 3 degrees. In practice, due to inaccurate sighting and hand trembling, the compass limb reference error should be considered at about 5 degrees. This gives a lateral displacement of about 100 meters per kilometer. Or about one tenth of the distance traveled.
Therefore, if, when moving along azimuths, the reference point indicated in the diagram does not appear in this place, then it must be sought within a circle whose radius is approximately 1/10 of the distance traveled, centered at the point where you stand. Having found the required reference point, in the future from it it is necessary to determine the distance and direction of further movement in azimuths.
Approximate time for the implementation of techniques and actions for orienting on the terrain and movement in azimuths.
In conclusion, we point out that for confident orientation and movement in azimuths on unfamiliar terrain and in any conditions, it is necessary to preliminarily work out individual techniques and actions for orientation. The table above shows the sequence of practicing techniques (actions) and the approximate time for their implementation.
