NEW YORK (Reuters) - A Boeing Co (BA.N) 787 Dreamliner took to the sky on Monday in the first of two flights aimed at showing that the plane's new lithium-ion battery system meets regulatory safety standards, a key step toward ending a two-month, worldwide grounding of the high-tech jet.

Monday's two-hour flight test, if successful, would allow Boeing to go ahead with a second flight test "in coming days" that would gather data to be submitted to the Federal Aviation Administration, Boeing spokesman Marc Birtel said.

The FAA and other regulators grounded the Dreamliner in mid-January after batteries overheated on two separate aircraft .

Resuming flights would be a huge boost for Boeing, which is losing an estimated $50 million a week while the 787 is grounded, and for airlines, which are barred from flying the 787. Boeing also is prevented from delivering the planes to customers during the grounding, though it continues to build them.

Some Boeing officials have said the jet could be back in service by May 1. But some experts cautioned it could take longer.

Oliver McGee, an aerospace and mechanical engineer who was a deputy assistant secretary of transportation under President Bill Clinton, said he was skeptical that federal regulators would allow the 787 to resume flights as early as May 1.
"Take whatever date is agreed upon and add three to six months to it," McGee told Reuters. "I don't think that you're going to see any type of quick fix or compromising on the FAA side."
McGee said the trauma of the Columbia and Challenger shuttle disasters would make federal officials reluctant to sign off on the new battery system until they were absolutely sure it would work as Boeing promised.
The first test flight took off Monday at approximately 12:11 p.m. Pacific time (1911 GMT) from Paine Field in Everett, Washington, on a two-hour mission designed to validate that all systems on the plane are working as designed. Video of the event showed the jet, with LOT Polish Airlines livery, soaring in a clear sky with snow-capped mountains in the distance.
Once data from the flight has been analyzed, Boeing said it would prepare for a ground and flight demonstration aimed at certifying the company's proposed changes to the battery system, a key step toward getting permission from the FAA to resume flights of the grounded plane.
Birtel said it wasn't clear if the demonstration test for the FAA would conclude Boeing's testing of the new battery system, which was unveiled in Tokyo on March 15. The tests are being conducted in the laboratory, in planes on the ground, and in flight.
"Obviously, progress is being made on all three fronts," Birtel said.
The battery system is made by Thales SA (TCFP.PA) of France, while the battery itself is made by Japan's GS Yuasa Corp .
Boeing plans to conduct one certification demonstration flight using the same LOT plane, Line number 86, to show that the new battery system performs as intended during flight conditions.

Separately, the U.S. National Transportation Safety Board on Monday said it would hold a two-day forum April 11-12 to examine the design and performance of lithium-ion batteries in transportation -- a comprehensive review sparked by the battery failures on the two Boeing 787 Dreamliners in January.

The public forum will examine the design and development of various lithium-ion batteries, how their use and manufacturing are regulated, and the use and safety of such batteries in various modes of transportation.
