A computerized method for providing a unified user interface to a plurality of flight management components encapsulated within a flight management system. The method can include receiving a flight management system input dataset from a first flight management system user interface device. The method can also include creating, with a processor programmed to provide a unified user interface, a plurality of flight management system input data portions to be transmitted to a plurality of destination flight management system components. The plurality of flight management system input data portions can be based on the flight management system input dataset and each flight management system input data portion can correspond to one of said plurality of destination flight management system components. Each of said plurality of flight management system input data portions can be transmitted from the processor to said corresponding destination flight management system component.
