Airports host multiple federal agencies that play key roles in the operations,safety, and security of their facilities. Planning and operation of airports across the United States may require accommodation of multiple federal agencies, but the legal authority defining airports’ rights and obligations to these agencies is varied and at times unclear.

ACRP Legal Research Digest 47: Accommodating Federal Agencies at Airports and Related Contractual Concerns, from TRB's Airport Cooperative Research Program, seeks to provide a single source of information concerning airports’ rights and obligations to accommodate federal agencies and to enter into cooperative agreements and other agreements.
