Distress radio beacons, also known as ELTs (emergency locator transmitters), are tracking transmitters which aid in the detection and location of aircraft in distress. After receiving a distress signal sent from ELT, the receiving center transmits it to the main or sub center for search and rescue operation coordination. This center takes actions for identifying the distressed aircraft and afterwards proceeds to send rescue teams by helicopter or planes. In many occasions, the center sends rescue team to the location which incurs heavy costs. It is noted that, search and rescue services, according to SAR convention, are given by the governments at no cost. Therefore, on receiving a distress signal, while there is no proof on the emergency situation of the distressed aircraft and the risk for its crew, the coordination centers proceed to send search and rescue teams and if the signal was a false one a heavy cost is incurred to the center, the research team works on evaluating this heavy cost. Based on data provided by the programme participants, Cospas-Sarsat calculates of false alert rates for 406 MHz identify as the "SAR false alert rate" which characterizes the impact of false alerts on SAR services, is the percentage of false alerts plus undetermined alerts over the total number of alerts transmitted to SAR authorities (table1) the SAR false alert rate was 95.3%, about one real alert in 20 alerts received. ELTs continue to have a higher beacon false alert rate. The total costs incurred in a ten years period, calculating for 705 centers all over the world, an amount of 396,402,325 dollars was obtained (note that, the fuel and calling costs in other countries might be much higher). Generally it can be said after being faced with several problems such as transmition of false distress and alert failure to respond appropriately and also spending lots of money for detecting the false distress alert.
Therefore the new equipment we have designed could be of help to ELT operation. We must say that have not a change in the structure and protocols of ELT devises Been passed in ICAO & ITU regulation. also used a satellite THURAYA mobile phone, none of the crew of would know of the activation of an alarm system that was not visible by the pilot. Now we have designed a system that informs the pilot the moment alarm system is activated.The system we have designed contacts the RCC immediately after the transmission of an alert and fully supervises it through a management monitor. even such aircraft can press a button to transmit distress alerts to RCCs
Advantages: Decreased chance of false alerts from ELTs; Significantly reduced role of humans in the activation of alarm systems and thus minimized the release of false alerts; User-friendlier interface through seeing and controlling all the stages of on an LCD display; Special attention to the other causes of false alerts and exerting modifications for their minimization.
