Abstract: Systems and methods for approach system selection are provided herein. In certain embodiments, a method includes receiving an approach identifier. Further, the method includes identifying a plurality of approach modes associated with the approach identifier. Additionally, the method includes selecting an approach mode in the plurality of approach modes based on an integrity measure of navigation guidance associated with separate approach modes in the plurality of approach modes. Moreover, the method includes providing the navigation guidance for the selected approach mode to an approach system for guiding a vehicle through an approach for the selected approach mode.
