Virgin Atlantic Airways will use Boeing’s Airplane Health Management System to monitor the in-flight condition of its 747-400 fleet. The Boeing system provides in-flight access to aircraft condition and fuel-burn information, enabling airlines to identify and correct problems that might be wasting fuel. Virgin Atlantic will use the health monitoring system on 13 747-400s. The selection was described as expanding a partnership the two companies have formed to develop environmental solutions. Boeing and Virgin Atlantic in April said they will work together to reduce fuel burn and cut aircraft emissions on the ground as well as developing sustainable biofuels suitable for commercial jet engines and the aviation industry.
