AgustaWestland has logged the first flight of the 4.5-metric-ton AW169 helicopter that it hopes to start delivering to customers in 2015.

The first of four flight-test aircraft flew on May 10 at the company’s Cascina Costa plant. Two more prototypes are to fly this year, with a fourth next year as AgustaWestland aims for civil certification in 2014.

During the mission “the helicopter performed as expected,” the company says, adding the flight included an assessment of general handling and basic systems.

AgustaWestland is trying to promote a helicopter family concept with the AW169 and the fielded AW139 and developmental AW189.

The twin-engine AW169 is aimed at the emergency medical services, police force and search-and-rescue market. The program was formally launched two years ago.
