The standards by which the FAA conducts these aeronautical studies are set forth in FAR Part 77. Specifically,FAR Part 77 establishes standards for: • FAA Notification.Notifying the FAA about any proposed construction or alteration of objects—whether permanent,temporary, or of natural growth—that could be a hazard to flight; • Imaginary Surfaces. Defining an airport's airspace,referred to as `imaginary surfaces'; and • Aeronautical Studies. Determining obstructions to navigable airspace and the potential hazardous effects of such obstructions on the safe and efficient use of that airspace. The FAA's authority to protect the navigable airspace from obstructions and other hazards, including existing and proposed structures, is predominantly derived from Title 49 U.S.C. Section 44718. However, Section 44718 does not provide specific authority for the FAA to regulate or control of off-airport real property.Nevertheless,the FAA does have authority to require that sponsors of new objects that could be airspace obstructions submit notice to the agency prior to the construction as outlined below. Persons failing to comply with the provisions of FAR Part 77 are subject to civil penalty under Section 902 of the Federal Aviation Act of 1958, as amended and pursuant to 49 U.S.C. Section 46301(a). If new airspace obstructions are created or, as may happen with the growth of trees or other vegetation, are newly identified, federal action is primarily limited to three possibilities: • Reduceddnstrumentokpproachd Minimums. For airports with instrument approaches, an obstruction could necessitate modification to one or more of the approach procedures (particularly greater visibility and/or cloud ceiling minimums) or even require elimination of an approach procedure. • ReduceddRunwayaLength.Airfield changes, such as displacement of a landing threshold, could be required(especially at airports certificated for commercial air carrier service). • Reducedd?ederalokid. The owner of an airport could be found in noncompliance with the conditions agreed to upon receipt of FAA grant assurances, airport development or property acquisition grant funds and could become ineligible for future grants (or,in extreme cases,be required to repay part of a previous grant). Subpart B,Notice of Construction or Alteration, of the regulations requires that the FAA be notified of any proposed construction or alteration of objects within 20,000 feet of a runway and having a height that would exceed a 100:1 imaginary surface(1 foot upward per 100 feet horizontally)beginning at the nearest point of the runway. This requirement applies to runways more than 3,200 feet in length; for shorter runways,the notification surface has a 50:1 slope and extends 10,000 feet from the runway; for heliports,the notification surface has a 25:1 slope and extends 5,000 feet from takeoff and landing area, also referred to as the FATO.Notification is required with regard to any public-use or military airport and heliport. Also requiring notification is any proposed object more than 200 feet in height regardless of proximity to an airport. SanfCarlosfAirportV B-14 ESAfAirportsfl130753f ALUCPfWhitefPape/ Junef2014f
