There has still been no confirmation of Indonesian media reports yesterday that the plane may have crashed off the coast of Belitung Island, roughly a third of the distance to Singapore from Surabaya along the flight path.
Singapore sends a second RSAF C-130 to join the search, according to local daily Today .
Indonesia searches the Java Sea on Monday for an AirAsia plane carrying 162 people that went missing yesterday morning after its pilot failed to gain permission to alter course to avoid a storm cell during a flight from Indonesian city of Surabaya to Singapore.
Flight QZ8501 did not issue a distress signal and disappeared five minutes after requesting a change of course on Sunday, says government and transport officials.
Air Force spokesperson Hasi Thahjanto says two C-130 Hercules planes are focusing their search efforts in areas northeast of Indonesia's Bangka island, which lies roughly halfway between Surabaya and Singapore, in the Java Sea.

Indonesia AirAsia is 49 percent owned by Malaysia-based budget carrier AirAsia. The AirAsia group, including affiliates in Thailand, the Philippines and India, has not suffered a crash since its Malaysian budget operations began in 2002.
Onboard Flight QZ8501 are 155 Indonesians, three South Koreans, one person each from Singapore, Malaysia and Britain, while the co-pilot is French.
There is bad weather in the area at the time and the aircraft has been flying at 32,000 feet before asking to fly at 38,000 feet to avoid clouds, says Joko Muryo Atmodjo, air transportation director at Indonesia's transport ministry.
Permission has not yet been given due to traffic in the area, and five minutes later, at 6.17am on Sunday (local time), the plane lost contact with air traffic control, Atmodjo adds.
The pilot "is requesting deviation due to en-route weather before communication with the aircraft is lost," the airline notes.
"We are cooperating with the relevant authorities to the fullest extent to determine the cause of this incident," says Indonesia AirAsia Chief Executive Sunu Widyatmoko.
The incident caps a disastrous year for Malaysia-affiliated airlines. Malaysian Airlines Flight MH370 went missing on March 8 on a trip from Kuala Lumpur to Beijing with 239 passengers and crew on board 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.
Like all affiliates of AirAsia, Indonesia AirAsia operates Airbus jets, of which it has 30 of the A320 model.
AirAsia has ordered several hundred jets from the European planemaker, making it one of its most important customers. The missing plane has been in service for just over six years, according to airfleets.net.
Indonesian officials from the civil aviation authority and transport safety committee, which are responsible for crash investigations, arrived in Surabaya on Sunday. A transport ministry official said Indonesia would handle the probe.
"The aircraft was registered in Indonesia and it looks to be missing over Indonesian territory, so we will lead the investigation," said the official, who asked not to be named as he was not authorised to speak to the media.
"We have the expertise to do this," Reuters reports .
