In the wild, the living environment is very harsh, and various disasters will come unexpectedly.
For wild survivors, it is necessary to understand the dilemma they are facing in time, so as to notify others in time and seek rescue.
When in distress and distress, contact others through various means.
The signal should be loud enough to attract attention, so understand the type of distress signal and how it is used.
The location where the signal is cast should be selected at the commanding heights.
According to their own situation and the surrounding environmental conditions, different distress signals are issued.
In general, signals that are repeated three times indicate a request for assistance.
<h1 class="pgc-h-arrow-right" >:</h1>
Fireworks are very effective as a contact signal.
In order to ensure its reliability, during the day, some moss, young branches, erasers, etc. can be placed on the fire to produce thick smoke; at night, more dry firewood can be put in place to make the fire burn vigorous and the flame rise.
Internationally, three fires are lit for help.
Arrange the fire in an equilateral triangle in the open, prepare green branches, oil or rubber around it, and create three thick smokes if needed, and make three loud whistles or three gunshots at the same time, at intervals of 1 minute, and then repeat.
If there are no such conditions, it is okay to light a bunch of fires.
It is not possible to make all the signal fire burn all day long, but it should be ready at all times, keep the fuel dry, and ignite as soon as any plane passes by.
The fuel of the fire should be easy to burn, and it should be able to ignite quickly after ignition, because some opportunities are fleeting.
Birch bark is ideal for fuel.
Gasoline can be used, but gasoline should not be poured on the fire.
Make a wick strip of some cloth, soak it in gasoline, then place it on a fuel pile, move the gasoline tank to a safe location and then ignite it.
If the fire is about to go out after ignition, make sure to add it to the fuel without sparks or residuals before adding gasoline.
It should be noted that fires cannot be ignited in the forest, which will cause harm to trees and threaten their own life safety.
A triangular bracket can be erected on the open ground, and the tinder can be placed on the bracket, which can separate the tinder from the wet ground and place more fuel.
You can cover the tinder with something colorful to get someone else's attention, or you can keep the tinder dry.
<h1 class="pgc-h-arrow-right" >2</h1>
During the day, smoke is a good locator that helps the aircraft find the target while indicating the wind direction of the ground, and the aircraft should land in the wind.
So add smoke-emitting materials to the fire.
After the smoke is lifted off, it forms a strong contrast with the surrounding environment and is easy to attract attention.
Bright smoke is evident at night or in the dark green jungle.
Adding wet items such as green grass, leaves, moss fresh and ferns can produce thick smoke.
In fact, anything damp produces smoke, damp grass mats and cushions can be smoked for a long time, and flying insects are difficult to approach and hurt people.
Black smoke is most striking in snow or desert, and rubber and gasoline can produce black smoke.
If weather conditions are limited, the fire can be increased, and as the heating current rises, the smoke will rise very high.
<h1 class="pgc-h-arrow-right" > three, ground-to-air signal:</h1>
Ground signs can be made on more open ground, such as meadows, beaches, and snow.
For example, cutting grass into certain signs, or stepping on certain signs on the snow; you can also use branches to form a certain sign to make contact with the air.
It can also be expressed using ground-to-air signals as specified in the International Civil Aviation Harmony.
The letters listed below are international emergency distress signals, and "FILL" can help you remember the main signals.
A single stick "I" is the most important and the easiest one to make.
The dimensions are approximately 10 meters long and 3 meters wide per signal, with each signal spaced 3 meters apart.
These codes should be used in open spaces, can make full use of the indicator boards in the lifebuoy pack, or can be made simply, with rocks and trees to make it more eye-catching. If it's snow, you can step on these signals directly with your foot and continue until the next time it snows.
<h1 class="pgc-h-arrow-right" >4</h1>
Tie a flag or a piece of brightly colored cloth to a wooden stick, make a long stroke on the left side and a short stroke on the right side, increase the amplitude of the action, and do a "figure 8" movement.
If the two sides are closer, there is no need to do a "figure 8" movement.
A simple stroke can be done, once on the left side and once on the right, the former should take slightly longer than the latter.
When the ground signal is received and understood, the aircraft should be piloted to tilt the fuselage during the day and do rocking movements; at night, the green light should be lit.
When a ground signal is received but is not understood, the aircraft should be piloted to the right-hand side during the day to circle; at night, a red light should be lit.
<h1 class="pgc-h-arrow-right" >5, sound signal:</h1>
If the rescuer is within hearing range, the shout also becomes a distress signal.
Therefore, it is possible to shout loudly, or it can make a sound with the help of other objects, such as hitting trees with axes, sticks.
Usually, the international alpine distress signal is to sound the whistle six times a minute (or wave six times, the fire shines six times, etc.), then be quiet for 1 minute, and then repeat.
Sixth, reflective signal:
Signal light can be reflected using sunlight and a mirror.
Any bright material can be used, such as can lids, glass, a piece of metal lead sheet, and a mirror is of course more ideal.
Continuous reflection will regularly produce a long line and a dot, which is a type of Morse code.
Even if you don't understand Morse code, casual reflections can be compelling.
In any case, at least you should master the SOS code.
Even if you are quite far away, you can detect a reflected light signal, and even if you don't know where you want to contact the target, it is worth trying.
Look around the sky, and if an airplane is approaching, quickly reflect the signal light.
This light may dazzle rescuers, so once you're sure you've been spotted, stop reflecting it.
<h1 class="pgc-h-arrow-right" >7</h1>
Any flash will attract attention, but still choose the best color.
In areas close to the woods, red light is prominent, while in snow, red and green light is best.
It is necessary to be familiar with various flash objects and correctly grasp the use method.
If used improperly, it may hurt itself.
The flash should be kept dry, away from flames and heat sources, and pay more attention to the safety of the fuse to ensure that it is not accidentally pulled out, and can be easily removed when needed.
<h1 class="pgc-h-arrow-right" >8, direction signal:</h1>
When leaving the dangerous place, you should leave some direction signals at a certain distance to indicate your forward direction so that rescuers can find it in time.
Ground signals allow rescuers to know where you are or where you've been in the past, and directional indicators help them find your path.
Keep leaving signs along the way, which will not only allow rescuers to follow them, but also not get lost when they want to return.
Once you are lost and can't find the route to take, the direction indicator becomes a guide.
Direction indicators can be used in a variety of ways to act as:
1. Support the stick between the tree rights, and point to the direction of action at the top.
2. Tie the upper part of the seedling in the curl, so that the top of the bend indicates the direction of action.
3. Place a forked branch on the ground and use the fork point to point to the direction of action.
4. Use small stones to form a large stone pile, and put a small stone on the side to point to the direction of action.
5. Use an arrow-shaped groove that is deeper than the trunk to indicate the direction of action.
6. Two crossed sticks or stones mean that the road is not accessible.
7. The signal conveyed by two rocks, sticks or bushes has obvious meaning, indicating danger or urgency.
