Head of the Meteorology and Geophysics Agency (BMKG) Sri Woro Harijono on Monday denied all previous claims that the Sukhoi Superjet 100 crashed into Mount Salak because of bad weather.
“There was no significant weather [problem] that could have disrupted the flight because there were no cumulonimbus clouds,” Woro said in a meeting with House Commission V that oversees transportation.
Cumulonimbus are at the lowest 600-meters above the ground and they usually indicate the presence of heavy rain and strong winds.
The BMKG report to the House differs from Indonesia’s Institute of Aeronautics and Space (Lapan) that said the Sukhoi Superjet encountered bad weather over Mount Salak before it collided with the mountain.
Lapan’s satellite observation data showed the presence of active thick rainclouds when the Sukhoi plane passed the mountain. The convective index was 30, meaning it was likely raining in the area. However, Lapan did not say the weather had caused the accident.
BMKG concluded weather did not cause the crash after analyzing satellite images and gathering observation data from the Darmaga Climatology Station in Bogor, located 10 kilometers from the crash point, and the Atang Sanjaya Climatology Station located 19 kilometers from the site.
The House of Representatives on Monday conducted a meeting to discuss the Sukhoi crash with the BMKG, the National Committee for Transportation Safety (KNKT), state airport operator Angkasa Pura II, the Transportation Minister, the National Search and Rescue Agency and Trimarga Rekatama, the Indonesian Representative of Sukhoi’s Civil Aircraft.
