National Aeronautics and Space Agency (Lapan) said Sukhoi Superjet 100 crashed while climbing Mount Salak on May 9 at 14:33 pm, the mountain is covered with towering cumulonimbus clouds as high as 37,000 feet (11.1 km)."The simple logic, the pilot will find the safest way out. But to raise the plane to overcome the cloud may be considered too high, from 10,000 feet to fly over 37,000 feet. Therefore, the choice was to find a way to the right, left, or down, "said Deputy Science, Assessment, and Aerospace Information Lapan Thomas Djamaluddin, when contacted from Jakarta, Saturday.Therefore, he explained, the choice of asking for permission to lower the altitude of 6,000 feet the aircraft may be based on the consideration that there are a few gaps which are shown below, but too late to take into account the risk of more fatal to the mountainous topography.He described, the data show around the time of the incident MTSAT, clouds around Mount Salak did look very tightly with cloud coverage of more than 70 percent.Analysis of convection indices that can describe cloud height also showed a significant index of about 30 of Cb clouds (cumulonimbus) towering up to about 37,000 feet (11.1 kilometers).Satellite data, he added, illustrates that the time of the incident, the plane surrounded by towering clouds. In the moments before it crashed, informed the plane dropped from a height of 10,000 feet (3 kilometers) to 6,000 feet (1.8 kilometers), whereas high-Salak mountain about 2.2 miles.However this analysis, he said, just based on weather satellite data, just to give an answer while based on data, not based on unfounded speculation."Comprehensive analysis of other factors of course we are waiting for the flight rekamanan analysis by the National Transportation Safety Committee (NTSC), though of course the weather still not be ruled out," Djamal said.Meanwhile, former Head of Technical Unit of Artificial Rain BPPT encountered Syamsul Bahri said that, while flying in the clouds encircling a pilot has a high risk for sudden rise or fall suddenly."That's why, every pilot is always to avoid the clouds to avoid this risk by flying far above the cloud coverage. However, the pilot may have not mastered this rugged terrain, "said the Head of Planning BPPT experienced fly for weather modification service it. (Reuters / ea )
