Rules And Procedures Aviation Abbreviations And Acronyms - SAFA
Rules and procedures Aviation abbreviations and acronyms The following consolidated list of 'abbreviations and acronyms' are commonly used in aviation and may be found throughout aviation legislation, operational manuals, in the AIP, on associated charts/maps, in NOTAMs, in AIP supplements in meteorological messages or in CASA literature. The list also includes the standards for weight and measurement purposes. The abbreviations and acronyms have been sourced from various areas, such as ICAO, AIP, WATOG, FARs, CARs 1988, CASR 1998, the AIS, IATA and CASA's consultation documents. The list is not exhaustive and should you identify a sourced abbreviation or acronym which does not appear on this list or you note an error in the list, please let CASA's Standards Project Administration Section know by email to review@casa.gov.au.
