CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION 

                               (CONTINUED)

 

PART 77_OBJECTS AFFECTING NAVIGABLE AIRSPACE--Table of Contents

 

                     Subpart C_Obstruction Standards

 

Sec. 77.21  Scope.





    (a) This subpart establishes standards for determining obstructions 

to air navigation. It applies to existing and proposed manmade objects, 

objects of natural growth, and terrain. The standards apply to the use 

of navigable airspace by aircraft and to existing air navigation 

facilities, such as an air navigation aid, airport, Federal airway, 

instrument approach or departure procedure, or approved off-airway 

route. Additionally, they apply to a planned facility or use, or a 

change in an existing facility or use, if a proposal therefor is on file 

with the Federal Aviation Administration or an appropriate military 

service on the date the notice required by Sec. 77.13(a) is filed.

    (b) At those airports having defined runways with specially prepared 

hard surfaces, the primary surface for each such runway extends 200 feet 

beyond each end of the runway. At those airports having defined strips 

or pathways that are used regularly for the taking off and landing of 

aircraft and have been designated by appropriate authority as runways, 

but do not have specially prepared hard surfaces, each end of the 

primary surface for each such runway shall coincide with the 

corresponding end of the runway. At those airports, excluding seaplane 

bases, having a defined landing and takeoff area with no defined 

pathways for the landing and taking off of aircraft, a determination 

shall be made as to which portions of the landing and takeoff area are 

regularly used as landing and takeoff pathways. Those pathways so 

determined shall be considered runways and an appropriate primary 

surface as defined in Sec. 77.25(c) will be considered as being 

longitudinally centered on each runway so determined, and each end of 

that primary surface shall coincide with the corresponding end of that 

runway.

    (c) The standards in this subpart apply to the effect of 

construction or alteration proposals upon an airport if, at the time of 

filing of the notice required by Sec. 77.13(a), that airport is--

    (1) Available for public use and is listed in the Airport Directory 

of the current Airman's Information Manual or in either the Alaska or 

Pacific Airman's Guide and Chart Supplement; or

    (2) A planned or proposed airport or an airport under construction, 

that is the subject of a notice or proposal on file with the Federal 

Aviation Administration, and, except for military airports, it is 

clearly indicated that that airport will be available for public use; 

or,

    (3) An airport that is operated by an armed force of the United 

States.
