GE Aviation said it won a contract with Southwest Airlines to upgrade the flight management systems for 200 Boeing 737s. Financial terms were not disclosed. Deliveries will take place next year and in 2009. "Our system is a key part of our customer’s plans to conduct Required Navigation Performance operations, and allows them to realize significant cost savings with lowered fuel consumption while simultaneously benefiting the environment with reduced emissions," said John Ferrie, president of systems for GE Aviation.
