61-10 Flight Obstruction Areas for Major Airports
The major airports are hereby designated to include John F. Kennedy International, LaGuardia, and U.S. Naval Air Station (Floyd Bennett Field). For the purposes of this Chapter, the runways for such airports shall be the runways as shown in the diagrams in Section 61-42 (Runways for Major Airports).
A flight obstruction area is hereby established in the vicinity of any such major airport.
Each flight obstruction area shall be divided into two parts, the Airport Approach District and the Airport Circling District, as described in this Section (and as shown, for convenient reference only, in the flight obstruction area maps available on request at the offices of the City Planning Commission).
The Airport Approach District comprises those parts of the flight obstruction area of any major airport which lie generally below the flight path of aircraft approaching or taking off from the runways of such airport, and, more specifically, below the following airport referenced imaginary surfaces: the approach surfaces, the transitional surfaces and those parts of the horizontal surface and the conical surface which coincide with such approach surfaces and transitional surfaces.
The Airport Circling District comprises those parts of the flight obstruction area of any major airport which lie generally below the flight path of aircraft circling such airport and, more specifically, below the following airport referenced imaginary surfaces: those parts of the horizontal surface and the conical surface which do not coincide with the approach surfaces and the transitional surfaces.
