Officials said more than 20 bodies have now been recovered, along with pieces of the broken-up plane, in the Indonesian-led search for Flight QZ8501 that is concentrated on 1,575 square nautical miles of the northern Java Sea.
Strong winds and heavy seas have stopped divers from looking for the fuselage of the Airbus A320-200, which plunged into the water on Sunday while en route from Indonesia's second-biggest city Surabaya to Singapore with 162 people on board.
"The waves could reach five meters this afternoon. Higher than yesterday," said air force Puma helicopter pilot Flight Captain Tatag Onne, who has been flying missions to recover bodies and debris from the sea.
"We look for breaks in the clouds where conditions improve so that we can approach. Yesterday, when we went to collect a body from the sea we couldn't because the body was being rolled by waves. Sometimes we could see it, sometimes we couldn't."
The multinational search operation based in Pangkalan Bun, the town in southern Borneo closest to the search area, was bolstered on Friday by experts from France's BEA accident investigation agency, which attends all Airbus crashes.
Officials said the French team's hydrophones - sophisticated underwater acoustic detection devices - and towed sonar equipment brought by other international experts could not be used on Friday because of high waves.
"The sea state has to be calm," General Sunarbowo Sandi of Indonesia's search and rescue agency said. "We cannot operate it in poor weather."
But naval vessels from Indonesia, the United States and Singapore with in-built anti-submarine capabilities were using sonar to sweep the sea floor, he added.
The cause of the crash - the first suffered by the AirAsia group since the budget operator began flying in 2002 - is unexplained. Investigators are working on a theory that the plane stalled as it climbed steeply to avoid a storm about 40 minutes into a flight that should have lasted two hours.
Officials earlier said it may take up to a week to find the black boxes, which investigators hope will unravel the sequence of events in the cockpit during the doomed jet's final minutes.
Even in bad weather, however, the search for the AirAsia plane is less technically challenging than the two-year search for an Air France jet that crashed into deep Atlantic waters in 2009, or the fruitless hunt for Malaysia Airlines Flight MH370 that disappeared last year.
Given Flight QZ8501 crashed in shallow seas, experts say finding the boxes should not be difficult if its locator beacons, with a range of 2,000 to 3,000 meters (6,560 to 9,800 ft) and a battery life of about 30 days, are working.
Twenty-two bodies have been recovered from the sea, Supriadi, mission co-ordinator for the Indonesian search and rescue agency, told a news conference. Debris such as luggage, an emergency slide and a life jacket has also been found.
The bodies are being taken in numbered coffins to Surabaya, where relatives of the victims, most of whom were Indonesian, have gathered. Authorities have been collecting DNA from relatives to help identify the bodies.
The first funeral one of the crash victims was held on Thursday, and on Friday officials said the remains of three more had been identified, including a flight attendant.
The plane was traveling at 32,000 ft (9,753 meters) and the pilots had asked to climb to 38,000 ft to avoid bad weather just before contact was lost. When air traffic controllers granted permission to fly at 34,000 ft a few minutes later, they got no response.
A source close to the investigation said radar data appeared to show the aircraft made an "unbelievably" steep climb before it crashed, possibly pushing it beyond the A320's limits.
"It appears to be beyond the performance envelope of the aircraft," he said.
Online discussion among pilots has centered on unconfirmed secondary radar data from Malaysia that suggested the aircraft was climbing at a speed of 353 knots, about 100 knots too slow, and that it might have stalled.
The Indonesian captain, a former air force fighter pilot, had 6,100 flying hours on the A320 and the plane last underwent maintenance in mid-November, according to Indonesia AirAsia, which is 49 percent owned by Malaysia-based AirAsia.
Three airline disasters involving Malaysian-affiliated carriers in less than a year have dented confidence in the country's aviation industry and spooked travelers.
Malaysia Airlines Flight MH370 disappeared in March en route 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.
On board Flight QZ8501 were 155 Indonesians, three South Koreans, and one person each from Singapore, Malaysia and Britain. The co-pilot was French.
earchers struggled with rugged, forested terrain Monday, trying to reach debris believed to be from an Indonesian airliner. They gave up when bad weather made it impossible to proceed and planned to try again Tuesday.

Indonesian navy divers retrieved the black box flight data recorder from the wreck of an AirAsia passenger jet on Monday, a major step towards investigators unraveling the cause of the crash that killed all 162 people on board.

The tail of a crashed AirAsia jet has been found upturned on the sea bed about 30 km (20 miles) from the plane's last known location, Indonesia's search and rescue agency said on Wednesday, indicating the crucial black box recorders may be nearby.
