FAA encourages airport sponsors to consider ongoing compliance with the Grant Assurances and other federal obligations as a part of airport master planning. We often assist airport sponsors as they review and update existing airport rules and regulations and minimum standards in this context. As our airport clients review objectives for allowing for a fair and competitive economic environment, we counsel them on how to ensure just conditions for protecting investments among service providers and how to remain consistent with industry trends and direction. We also advise sponsors on compliance with existing rules and regulations and minimum standards.
