The aeronautics commission has operational control of airports constructed under section 2-06-01.1 and may provide for the imposition of landing fees, granting of fuel and service concessions, or the lease of portions of the premises for other related airport services or for purposes consistent with the use of the premises for airport purposes. All income from the operation of such airports must be deposited in the state treasury in a special operating fund to be known as the airport operating fund. All expenditures from such fund must be within the limits of legislative appropriations and must be made upon vouchers, signed and approved by the director of the aeronautics commission.
