The federal government's Joint Agency Coordination Centre (JACC), which is overseeing the search, in a statement said 10 military planes, four civil jets and nine ships will scour for the plane that disappeared on March 8.
The search will focus on three areas within the same vicinity in the Indian Ocean. The first aircraft left for the search area early this morning.
A total of 26 State Emergency Service (SES) volunteers from Western Australia, New South Wales and Victoria will work as air observers on three of the civil aircraft.
"The other civil aircraft will operate as a communications relay," the statement said.
Fair weather is forecast for the search area on Friday, with visibility around 10 kilometres and a cloud base between 1000 and 2000 feet, JACC said.
The Australian Transport Safety Bureau continued to refine the area where the aircraft entered the water based on continuing ground-breaking and multi-disciplinary technical analysis of satellite communication and aircraft performance, passed from the international investigative team comprising analysts from Malaysia, US, UK, China and Australia.

MH370 'black box' ship due in search zone

Australian navy vessel Ocean Shield, which is fitted with a US-supplied "black box" detector, was on Friday expected in the area being scoured for wreckage of Flight MH370 as 14 planes continued the arduous search.
Nearly a month after the Malaysia Airlines jet carrying 239 people vanished authorities still have no idea how or why it crashed and warn that unless the black box is found, the mystery may never be solved.
But finding the flight data recorder using the towed pinger locator on Ocean Shield appears increasingly remote with officials warning that without a confirmed crash site, hopes of recovering the device are slim in the vast and unpredictable southern Indian Ocean.
Time is also ticking with the battery-powered signal from the black box expected to expire within days. Ocean Shield left Perth on Monday evening for the three-day voyage to the search zone.
The British navy's hydrographic ship HMS Echo is already in the area and spent scouring for sonic transmissions from the flight data recorder on Thursday.
"One alert was experienced but discounted. False alerts may be experienced from biological sources such as whales or interference from shipping noise," the Perth-based Joint Agency Coordination Centre (JACC) said.
‘We will give plane families closure’

Leaders of the two countries heading multinational efforts to solve the mystery of Malaysia Airlines Flight 370 pledged that no effort would be spared to give the families of those on board the answers they need.

Najib, whose government has been harshly criticized by some victims' families for giving sometimes conflicting information about the flight and for the slow pace of the investigation, said everyone involved in the search is thinking of the families of victims who are waiting desperately for news.
"I know that until we find the plane, many families cannot start to grieve. I cannot imagine what they are going through. But I can promise them that we will not give up. We want to provide comfort to the families and we will not rest until answers are indeed found. In due time, we will provide a closure for this event," he said.
