The 757 and 767 airplanes provide maximum commonality in equipment, flight deck configuration and handling characteristics. Pilots with three-crew ratings will be qualified to fly either airplane with a three-crew requirement, and those with two-crew ratings will have the same flexibility.In addition to crew qualification, over 80% of the LRUs in the Flight Management System are interchangeable between similar crew configurations of the 757 and 767, i.e., they have the identical part number. Seventy-five percent of the LRUs are common to both the two-and three-crew configurations. Components that have engine-related software (the Thrust Management and Flight Management Computers) will be interchangeable between 757 and 767 aircraft powered by engines from the same manufacturer.For the operators, this commonality will simplify crew training, reduce maintenance and support costs, increase opportunities for pooling airplanes between airlines, and reduce dispatch delays due to wider availability of spares.
