When seeking help, the signal plays a decisive role. Once the two parties have established contacts, it is necessary to use the code for further communication, which also facilitates the increase of the signal's function and facilitates the identification of signals. Using code in search, patrols can understand.
If the survivor wants to get out of danger through the plane, he must find a landing site for the plane or helicopter. Be careful in front of the helicopter.
Use signals for help
The primary prerequisite for obtaining assistance is to make others aware of their situation. If possible, give your own position. Once contacted, send out other information.
Some of the distress signals are internationally common. The English letter SOS (saveoursoul—the abbreviation for saving us—) is perhaps the most widely known. Signals can be written underground, or sent by radio, or they can be spelled out in semaphores or sent out by other means.
The signal Mayday (from French maidez--help me) is the most common radio signal contact between ships and airplanes.
Vehicle or aircraft wreckage
If you are with an anchored car or a falling plane, you can find a variety of useful sources. If the vehicle or aircraft has not yet caught fire, fuel, gasoline, and liquid that can be burned can be found. Tires and insulators can produce heavy smoke when they are lit.
Glass and chrome can be made into large reflectors, especially engine hoods and turbine covers. The life jackets, rubber rafts and parachutes are bright and eye-catching and easily detected. Place these brightly colored and bright objects around you. This location is most likely to attract the attention of rescue workers.
In the evening, the lights are turned on when the plane passes through or may be rescued. If the battery power is constantly declining, let the light flash and save as much power as possible. At the same time, other methods such as clicking sounds are noticeable.
Fireworks signal
Ignition - flames and smog - is a good way to attract attention. Once an injury is in urgent need of treatment or an environment is in need of rescue, one of the first tasks is to light the signal fire. If there are a large number of people, allocate some of them to collect fuel as soon as possible to light the campfire and signal fire.
Cast signal location
Signal to fully consider the surrounding terrain. When you send out a light signal, you have to choose a commanding height, or you can erect an unusual object on the ridge to attract attention.
Mostly ask for help on a flat surface. In normal aerial search activities, if a slope cannot be ignored, the marking can of course be placed on the slope.
When an aircraft searches in the mountains, it mostly starts at the foot of the mountain and goes to the ridge. Therefore, a total-value slope may be hidden behind the ridge, and it is difficult for aircraft to fly. If there is no certainty in mind, put the signal closer to the top of the hill so that the rescue aircraft can find out from any angle.
International code
Once the two parties have established initial contact but are unable to communicate orally, the use of more complex international common code can clearly communicate their basic needs and key ideas.
In air or sea rescue, it is necessary to prepare a landing site or help rescue personnel to operate some ropes and instruments. Some related basic knowledge will be greatly facilitated.
Transmitter
Ships equipped with rubber rafts, lifeboats and even individual life jackets can send messages indicating their location. Of course, over a certain distance, the signal is difficult to receive and the delivery is futile. Many radio transmitters have a certain scope of use. Be careful to save the battery and try your best to avoid wasting precious electricity until you have the opportunity to receive it and send a signal. If there are high-capacity radio equipment, signals should be sent immediately, with a fairly regular interval of transmission.
Looking at the instructions of all telex devices, the transmitters on ships and aircraft can be used in many wavelength ranges, but some emergency equipment has been adjusted to a fixed help channel.
Typically, a portable VHF transceiver used by a climber can only contact a ground station on the same line, and there can be no obstacles in the middle (although it may sometimes establish a permanent one at a strategic commanding height. Interruption station). This kind of equipment usually adjusts the frequency of mountain rescue, and the operating procedure is established before departure.
If you have a telegraph machine that can work around you, check the battery condition: Can the vehicle engine continue to generate electricity? Or can the battery be recharged? In order to reduce the power loss, a mode signal is sent out in a planned manner instead of attempting to continuously send signals for a long time. If the signal is received, rescue workers can calculate the time to receive the signal again.
sound
If the rescuer is within hearing range, snoring is also a basic way of attracting attention. In addition to the popular SOS, the international alpine SOS signal sent out six whistle minutes (or six waves, six flares, etc.) in one minute, followed by a minute's silence and repeated.
imagination
The idea of ​​whether there is any information in the bottle is bizarre but not exclusive. The use of a drifting bottle in the middle of the Pacific Ocean indicates that a shipwreck requesting assistance will of course have very few chances of success, but if in the river, a river object carrying clear and specific information can attract attention - for example, the sail of a small raft is marked with SOS. mark. Play your own imagination and ponder ways to arouse people's attention to you or your situation, but do not use valuable energy and resources.
Self-support
If it is impossible to achieve rescue, then the best plan can only be to return through your own efforts, but you should leave a clear mark behind them. Once the rescue personnel find the location of the accident, they can get hints and pursue your whereabouts. On the way back, if you are closer to the flight path or walking in a more open area, you have the opportunity to get attention.
