accidents. DoD analyses have determined that the areas immediately beyond the ends of runways and along the approach and departure flight paths have significant potential for aircraft accidents. Based on these analyses, DoD developed three zones that have high relative potential for accidents. The CZ, or area closest to the runway’s end, is the most hazardous area. The overall risk of an accident is so high that DoD generally acquires the land through purchase or easement to prevent development. APZ I is an area beyond the CZ that possesses a significant potential for accidents. APZ II is an area beyond APZ I having lesser, but still significant potential for accidents. While the aircraft accident potential in APZs I and II does not warrant land acquisition by the Air Force, land use planning and controls are strongly encouraged in these areas for the protection of the public. The CZs for the runways at Plant 42 are 3,000 feet wide by 3,000 feet long. APZ I is 3,000 feet wide by 5,000 feet long, and APZ II is 3,000 feet wide by 7,000 feet long. Additional information on the methodology associated with accident potential is contained in Volume II, Appendix B of this report. CZs and APZs are normally rectangular in shape, extending from the runway along the axis of its centerline but in certain circumstances a CZ and APZ can be curved. 3.2 Airspace Control Surfaces Airspace Control Surfaces or “Imaginary Surfaces” are graphic representations resulting from the application of criteria for height and obstruction clearance found in the CFR, Title 14, Part 77 (14 CFR 77) and in Air Force design standards for its airfields. The design standards for Plant 42 are found in the DoD’s Unified Facility Criteria (UFC) 3-260-01 Airfield and Heliport Planning and Design (Figure 3-1). Under the standards of the UFC, both runways at Plant 42 are Class B runways (designed and routinely used for fighter, heavy, jet aircraft as opposed to runways designed and routinely used by light, propeller aircraft). For a more complete description of obstruction evaluation/airport airspace analysis (OE/AAA), see FAR Part 77 and the UFC. Additional information on this topic is provided in Volume II, Appendix D. The purpose of these airspace control surfaces is to prevent construction of structures whose height would tend to compromise the ability of airplanes to land in adverse weather and, in the case of military airfields, to designate airspace required to safely conduct military training maneuvers. During periods of adverse weather conditions, course guidance is provided to pilots and In a 14 CFR 77 analysis, the heights of natural or man-made objects are examined to determine whether such objects would be hazardous to air navigation; this analysis is named after the section of the Federal Aviation Regulations (FAR Part 77) that set forth the applicable standards. Another term often used in this line of inquiry is “imaginary surfaces.” Imaginary surfaces project outward from an airfield, either parallel to the runway or inclined at an angle. 3-2
