SEC. 4. COST ALLOCATION STUDY. The Secretary of Transportation shall conduct a study respecting the appropriate method for allocating the cost of the airport and airway system among the various users, and shall identify the cost to the Federal Government that should appropriately be charged to the system and the value to be assigned to any general public benefit, including military, which may be determined to exist. I n conducting the study the Secretary shall consult fully with and give careful consideration to ^^^^ views of the users of the system. The Secretary shall report the results of the study to Congress within two years from the date of enactment of this title.

As used in this part— (1) "Airport"' means any area of land or water which is used, or intended for use, for the landing and takeoff of aircraft, and any appurtenant areas which are used, or intended for use, for airport buildings or other airport facilities or rights-of-way, together with all airport buildings and facilities located thereon. (2) "Airport development" means (A) any work involved in constructing, improving, or repairing a public air[X)rt or portion thereof, including the removal, lowering, relocation, and marking and lighting of airport hazards, and including navigation aids used by aircraft landing at, or taking off from, a public airport, and including safety equipment required by rule or regulation for certification of the airport under section 612 of the Federal Aviation Act of 1958, and (B) any acquisition of land or of any interest therein, or of any easement through or other interest in airspace, including land for future airport development, which is necessary to permit any such work or to remove or mitigate or prevent or limit the establishment of, airport hazards.

(5) "Airport system planning means the development for planning purposes of information and guidance to determine the extent, type, nature, location, and timing of airport development needed in a specific area to establish a viable and balanced system of public airports. I t includes identification of the specific aeronautical role of each airport within the system, development of estimates of systemwide development costs, and the conduct of such studies, surveys, and other planning actions as may be necessary to determine the short-, intermediate-, and long-range aeronautical demands required to be met by a particular system of airports. (6) "Landing area" means that area used or intended to be used for the landing, takeoff, or surface maneuvering of aircraft. (7) "Government aircraft" means aircraft owned and operated by the United States.
