(1) The impact on VFR/IFR aviation DEPARTURE/arrival operations, air traffic procedures, minimum flight altitudes and existing, planned or planned airports listed in § 77.15(e) about which the FAA has received effective notification prior to the publication of a final decision. (a) This subsection applies to any aeronautical study of a proposed design or modification that requires notice to the FAA under section 77.9. (3) Notice of existing airports where advance announcements of the construction or conversion of the airport have not been made in accordance with Part 157 of 14 CFR. (c) Notices received by the FAA under this subsection shall be used to: (b) Objects that are considered obstacles under the standards described in this paragraph are presumed aviation hazards, unless other aeronautical studies conclude that the object does not constitute a hazard. Once another aviation study has been initiated, the FAA will use the standards in this subsection as well as FAA guidelines and directives to determine whether the object poses a threat to aviation. (c) any highway, railroad or other movable object crossing of a height that, when inclined upwards for an interstate highway that is part of the National Military and Interstate Highway System, where the crossings are designed for a vertical distance of at least 17 feet, for any other public highway of 15 feet, 10 feet or the height of the highest moving object; that would normally cross the road, whichever is greater, for a private road, 23 feet for a railway and for a waterway or other cross-road not mentioned above, an amount equal to the height of the highest moving object it would normally cross would exceed a standard in paragraph (a) or (b) of that section. (b) the approach area. The approach zone begins at each end of the primary area of the heliport with the same width as the primary area and extends outwards and upwards over a horizontal distance of 4,000 feet, with a width of 500 feet. The inclination of the approach zone is 8 to 1 for civilian helipads and 10 to 1 for military helipads.
Part 77 of the Civil Aviation Rule prescribes rules for persons who propose to construct or modify a structure that could present a danger in navigable airspace. Potential aviation hazards are listed on the CAA website. (1) 17 feet for an interstate highway that is part of the national system of military and interstate highways, where grade crossings are designed for a vertical distance of at least 17 feet. (5) The surface of a take-off and landing area of an airport or imaginary area determined in accordance with § 77.19, 77.21 or 77.23. However, no part of the take-off or landing area itself is considered an obstacle. 5. Notify the air carrier community of the construction or modification of objects affecting navigable airspace, including, if necessary, the revision of maps. (1) Airport proposals submitted pursuant to Part 157 of 14 CFR.
(1) the impact on the arrival, departure and itinerary procedures of aircraft operated in accordance with visual flight rules; This subsection describes the standards used to identify obstacles to air traffic control, aids to navigation or navigation devices. These standards apply to: (6) the DoD`s proposals on shared (civil-military) airports. (3) Height within a terminal obstacle distance zone, including a first approach segment, a starting area and a circular approach zone, which would cause the vertical distance between a point in the object and a specified minimum height of instrument flight in that range or segment to be less than the required obstacle clearance. (e) The standards in this Subsection apply to proposals to construct or modify an airport (including heliports and seaplane bases with marked lanes) if that airport is one of the following airports before the final decision is made: (b) you may not submit a request for discretionary review to determine the hazard emitted by a temporary structure, a marking and lighting recommendation, or where a proposed structure or modification does not exceed the barrier standards set out in Subsection C of this Part. (a) this Subsection describes the standards used to identify obstacles to air navigation that may affect the safe and efficient use of navigable airspace and the operation of planned or existing air navigation and communication facilities; These facilities include air navigation services, communications equipment, airports, Federal Airways, instrument approach or departure procedures, and approved off-lane out-of-airway itineraries. The following imaginary surfaces of the civil airport are defined in relation to the airport and each runway. The size of each of these imaginary surfaces depends on the category of each runway depending on the type of approach available or planned for that runway. The inclination and dimensions of the approach surface applied to each end of a runway shall be determined by the most accurate approach procedure present or intended for that end of the runway.
(5) the minimum heights for the removal of obstacles, the minimum heights of instrument flight rules, approved or planned instrument approach procedures and departure procedures; (b) Unless extended, revised or terminated, any non-endangerment of aviation established under this Subsection shall expire 18 months after the day on which the provision comes into force or on the date on which the proposed construction or modification is abandoned, whichever comes first. (c) The disability standards set out in Subsection C of this Part shall be supplemented by other manuals and guidelines used to determine the impact of a proposed design or modification on navigable airspace. If the FAA requires additional information, it may forward a study to interested parties for comment. (a) is requested by the developer in respect of a construction or alteration project for which notification is submitted; or (a) objects of natural growth, land or construction or permanent or temporary modification, including the equipment or materials used and any permanent or temporary equipment. (3) Establish appropriate labelling and lighting recommendations using FAA Advisory Circular 70/7460-1, Marking and Lighting of Obstacles; The seaplane base is considered an airport only if its sea routes are delimited by visual markings. .
