The embodiments described herein can provide systems and methods for combining traditional navigational data with temporary updates. Such a system and method can facilitate the inclusion of temporary navigational events into the navigational data made available on aircraft flight management system (FMS). For example, the systems and methods can be used to combine Aeronautical Information Regulation and Control (AIRAC) navigational data that is traditionally updated on 28 day cycles, with temporary navigational data changes, such as those typically indicated in “Notices to Airmen” (NOTAM). The combined navigational dataset can then be provided to the FMS.
