What is one of the primary interests that Grant Assurances aim to balance?

The primary interests that Grant Assurances aim to balance involve ensuring compliance with FAA requirements related to the funding and expenditure of public air transportation. This includes the proper use of federal funds allocated to airport developments and operations, which are crucial to maintaining an efficient and safe air transportation system.

Grant Assurances serve as a contractual obligation for airports that receive federal funds, ensuring that these funds are utilized to support not only the airport's immediate needs but also the broader goal of providing effective and accessible public air transportation services. Balancing these requirements is essential to uphold the integrity of the federal funding process and to ensure that public investment leads to tangible improvements and benefits for users of the airport system.

Other options address important aspects related to airport management and operations, like streamlining processes or standardizing safety measures, but they do not encapsulate the foundational intent behind Grant Assurances, which focuses primarily on compliance with FAA regulations and the oversight of expenditures related to public air transportation.
