In an attempt to define the geography of risk around an airport, the 2011 Handbook includes an analysis of more than 10 years of aircraft accident data; identifying general accident patterns. While precedent is not predictive of future events (i.e.,because accidents occur in certain locations does not guarantee that it will happen again in the exact same places),this information provides a reasonable basis for defining broad areas within which a significant number of aircraft accidents have occurred in the past. Based on this data,the 2011 Handbook identifies a series of six safety zones,which are defined as follows: • Zone 1: Runway protection zone and within runway object free area adjacent to the runway; • Zone 2: Inner approach/departure zone; • Zone 3: Inner turning zone; • Zone 4: Outer approach/departure zone; • Zone 5: Sideline zone; and • Zone 6: Traffic pattern zone. Proposed safety zones for the San Carlos Airport ALUCP update are depicted on Exhibito3-3. These zones are based on the dimensions recommended by the Handbook for a"short"(i.e.,< 4,000 feet) general aviation runway.6 However, given the size of the local traffic pattern used by fixed-wing aircraft at San Carlos Airport(east of Runway 12-30),the dimensions of Zone 6 have been enlarged to encompass the local traffic pattern used by fixed-wing aircraft as represented by actual radar flight tracks. ExhibitO3-3 depicts the original and modified versions of Zone 6 and the radar flight track data. Exhibitn3-3a presents a close-up view of the safety zones and provides the dimensions for each of the safety zones. 6 Runway 12/30 is 2,600 feet long and 75 feet wide.
