The penetration may be in the lateral, the vertical plane or a combination of the two. Note.- Regions (SNET): The functions of regions (SNET) is to provide a means of assigning particular characteristics to volumes of airspace.

"Occurrence" is defined as "accident or incident" throughout this taxonomy. Generally, accidents and incidents differ only in the degree of injury sustained by persons involved or in damage sustained to the aircraft. Each category has a unique name and identifier to permit common coding in accident/incident systems, a text definition, and usage notes to further clarify the category and aid in coding occurrences. An important element of the occurrence category design is that it permits the association of multiple categories with an occurrence. Multiple coding supports the primary focus of CICTT- accident PREVENTION, in which every pertinent element should be investigated, recorded, and analyzed. Based on version October 2013 (4.6)
