GE Aviation was selected to provide flight management systems for 200 737 Classics operated by Southwest Airlines in what may be the largest cockpit retrofit program announced to date.

The technology upgrade is in keeping with SWA's plan to implement Required Navigation Performance at every airport it serves.

Value of the deal was not disclosed.

Deliveries are scheduled for 2008-09.

The FMSs will be supplied by the Systems division of GE Aviation, formerly Smiths Aerospace.

"Southwest is pleased to select GE to provide this key capability to our Classic aircraft, which will enable our entire Boeing 737 fleet to operate more efficiently in today's air traffic environment," said Executive VP and Chief of Operations Mike Van de Ven.
