Q-F08. How is the NPIAS airport categorization used to determine BIL AIG Allocated funds for non-primary airport sponsors?

Under BIL, not more than $500 million is allocated annually to non-primary airports based on the categories published in the NPIAS, updated with current year data. FAA Order 5090.5, Formulation of the NPIAS and ACIP, defines the criteria for each category or role.
