Object spotted in sea not from AirAsia plane: Indonesian VP

Military and rescue authorities monitor progress in the search for AirAsia Flight QZ8501 in the Mission Control Center inside the National Search and Rescue Agency in Jakarta December 29, 2014. REUTERS PhotoAn object spotted during a sea search for an AirAsia plane was not from the aircraft, Indonesian Vice President Jusuf Kalla said Dec. 29 after reports that an Australian surveillance aircraft had found something.
"It has been checked and no sufficient evidence was found to confirm what was reported," Kalla told a press conference at Surabaya airport from where the ill-fated plane departed.
Australia, Singapore and Malaysia have deployed planes and ships to assist in the Indonesian search for Flight QZ8501, which disappeared over the Java Sea on Dec. 28 en route to Singapore.
The Indonesia AirAsia plane, an Airbus A320-200, disappeared after its pilot failed to get permission to fly higher to avoid bad weather during a flight from the Indonesian city of Surabaya to Singapore on Dec. 28.
Meanwhile, officials have said the flight QZ8501 did not issue a distress signal and disappeared over the Java Sea five minutes after requesting the change of course, which was refused because of heavy air traffic.
"Based on our coordinates, we expect it is in the sea, so for now (we think) it is on the sea floor," Soelistyo, head of Indonesia's search and rescue agency, told reporters when asked about the missing plane's likely location.
Onboard Flight QZ8501 were 155 Indonesians, three South Koreans, and one person each from Singapore, Malaysia and Britain. The co-pilot was French.
The incident caps a disastrous year for Malaysia-affiliated airlines, with Indonesia AirAsia 49 percent owned by Malaysia-based budget carrier AirAsia.
Malaysia Airlines Flight MH370 went missing on March 8 on a trip from Kuala Lumpur to Beijing with 239 passengers and crew and has not been found. On July 17, the same airline's Flight MH17 was shot down over Ukraine, killing all 298 people on board.
The AirAsia group, including affiliates in Thailand, the Philippines and India, had not suffered a crash since its Malaysian budget operations began in 2002. The group's shares in Kuala Lumpur fell as much as 12.9 percent on Monday.
Indonesian Air Force spokesman Hadi Thahjanto said earlier two C-130 Hercules planes were focusing the search for Flight QZ8501 in areas northeast of Indonesia's Bangka island, which lies roughly halfway between Surabaya and Singapore, in the Java Sea.
Australian, Malaysia and Singapore sent navy ships and aircraft to join the search. China also offered to send planes and ships to help in the search, as well as any other assistance Indonesia needed.
Soelistyo said Indonesia might not have the best technology to search underwater and had accepted offers of help from the United States, Britain and France. In 2007, it took Indonesia months to recover flight data recorders from a Boeing 737-400 operated by Indonesia's Adam Air which crashed off Sulawesi island, killing all 102 people on board.
According to Indonesian Navy Flight Commander Laksamana Pertama Sigit Setiyanta the sea depths around the Bangka Belitung islands is only 25 to 50 metres (75-150 feet).
Flight QZ8501 was travelling at 32,000 feet above the Java Sea and had asked to fly at 38,000 feet to avoid clouds, said Joko Muryo Atmodjo, air transportation director at Indonesia's transport ministry.
Permission was not given at the time due to traffic in the area. Five minutes later, at 6:17 a.m. on Sunday (2317 GMT Saturday), the plane lost contact with air traffic control, Atmodjo said.
Data from Flightradar24.com, which tracks airline flights in real time, showed several nearby aircraft were at altitudes ranging from 34,000 to 36,000 feet at the time, levels that are not unusual for cruising aircraft.
Pilots and aviation experts said thunderstorms, and requests to gain altitude to avoid them, were not unusual in that area.
"The airplane's performance is directly related to the temperature outside and increasing altitude can lead to freezing of the static radar, giving pilots an erroneous radar reading," said a Qantas Airways pilot with 25 years experience flying in the region.
The resulting danger is that pilots take incorrect action to control the aircraft, said the pilot, who requested anonymity.
In such an emergency the pilots would likely have been wrestling to regain control of the aircraft and not had time to issue a distress signal, the Qantas pilot said.
Online discussions among pilots centred on unconfirmed secondary radar data from Malaysia that suggested the missing plane was climbing at a speed of 353 knots, about 100 knots too slow in such weather conditions.
"At that altitude, that speed is exceedingly dangerous," Sydney-based aviation expert Geoff Thomas told Reuters.
"At that altitude, the thin air, the wings won't support the aircraft at that speed and you get an aerodynamic stall."
Safety authorities say accidents involving a loss of control, such as might occur in bad weather, are rare but almost always catastrophic.
'My heart bleeds'
The Indonesian pilot was experienced and the plane last underwent maintenance in mid-November, the airline said. The aircraft had accumulated about 23,000 flight hours in some 13,600 flights, according to Airbus.
Malaysia AirAsia chief Tony Fernandes flew to Surabaya and, along with Indonesian officials, updated distraught relatives of passengers at a makeshift crisis centre at the airport in Indonesia's second-largest city.
"Keeping positive and staying strong," he said on Twitter.
"My heart bleeds for all the relatives of my crew and our passengers. Nothing is more important to us," he said.
Indonesia's Transportation Ministry said the government would review AirAsia's Indonesian business unit to improve safety.
Indonesian President Joko Widodo urged his people to pray for the safety of the passengers and crew. Such sentiments were echoed by other world leaders, including Pope Francis.
Louise Sidharta was at Singapore's Changi Airport waiting for her fiance to return from a family holiday.
"It was supposed to be their last vacation before we got married," she said.
