PETALING JAYA: The search sector for Indonesia AirAsia Flight QZ8501 has been moved 30 nautical miles to the east on Friday.
Royal Malaysian Navy chief Tan Sri Abdul Aziz Jaafar tweeted that a new sector numbering has been introduced in the search for the ill-fated flight.
He added that the "most probable area" was established with a dimension of 1,575 sq nautical miles.
"This is most likely the area of the missing plane," he wrote while tweeting an image mapping out the search area.
Abdul Aziz said that KN Baruna Jaya 1, MV Geo Survey and KN Hidayat were the ships tasked to the "most probable area", while KD Pahang and KD Lekiu were tasked in sector II (2619 sq nm) whilst KD Lekir in sector III (3375 sq nm).
He added that diving teams from the Indonesian national search and rescue agency (Basarnas) were ready to carry out underwater search.
Flight QZ8501 with 162 people on board was travelling at 32,000 feet (9,753m) and had asked to fly at 38,000 feet to avoid bad weather.
When air traffic controllers granted permission for a rise to 34,000 feet a few minutes later, they received no response.
It lost contact with the Jakarta Air Traffic Control about an hour after take off and was confirmed to have crashed on Dec 30 after debris found around the area of last point of contact was confirmed to have been from the plane.
Nine bodies have so far been recovered from the Airbus A320-200.
