All revenue bonds shall be payable solely from the revenues or income to be derived from the terminals, terminal facilities, airfields, airports, or port facilities or any part thereof. The bonds may bear any date or dates and may mature at any time or times not exceeding 40 years from their respective dates, all as may be provided in the ordinance authorizing their issuance.

The holder or holders of the bonds or interest coupons appertaining thereto issued by the District may bring civil actions to compel the performance and observance by the District or any of its officers, agents, or employees of any contract or covenant made by the District with the holders of the bonds or interest coupons and to compel the District and any of its officers, agents, or employees to perform any duties required to be performed for the benefit of the holders of any such bonds or interest coupons by the provision in the ordinance authorizing their issuance, and to enjoin the District and any of its officers, agents, or employees from taking any action in conflict with any such contract or covenant, including the establishment of charges, fees, and rates for the use of facilities as provided in this Act.
Notwithstanding the form and tenor of the bond, whether revenue or general obligation, and in the absence of any express recital on the face thereof that it is nonnegotiable, all bonds shall be negotiable instruments. Pending the preparation and execution of any such bonds, temporary bonds may be issued with or without interest coupons as may be provided by ordinance.
