Scientists are developing algorithms to save aircraft from dangerous volcanic material.
Michael Pavolonis, scientist in physics National Oceanic and Atmospheric Administration has become one of the initiators of the development of this new algorithm.
"Periodic detection is a crucial aspect [dalam pengembangan algoritma ini], "Said Pavolonis in his report.
The development of the new algorithm is based on the concern over the threat that active volcanic eruptions can pose to the world of aviation. Five to ten minutes, the time required for a hot volcanic material to spray up to 11 kilometers altitude, reach the height normally used by aircraft and destroy the engine.
As Pavolonis said, the operation of the algorithm depends on the role of imaginary satellites around the plane. Later, the proposed satellite will have the ability to measure the temperature, altitude and trajectory of the ashes that are spreading. Three minutes is the average time it takes for the satellite to detect a hazard.
This algorithm digitizes the images taken by meteorological satellites, such as the NOAA or NASA satellites, to the Himawari-8 Japanese. These satellites encircle the equator to take pictures of large patches of the Earth at regular intervals every 30 seconds.
After detecting the presence of a danger, the satellite automatically sends a notification to the flight authority. Later, it will also be developed to be able to convert volcanic ash into approach to safer particles. However, to reach this stage, additional research is still needed.
This algorithm can certainly be very useful for ensuring the safety of an aircraft's journey, especially when flying volcanoes in remote areas. Active mountains located in remote areas and lacking infrastructure are indeed a scourge for aviation. According to field data, only about 10% of the 1,500 active volcanoes in the world are subject to official and periodic monitoring.
