Starting July 1, 2008, all airplanes operating internationally will need to carry at least one emergency locator transmitter (ELT), according to a proposed standard from the International Civil Aviation Organization (ICAO). The proposal also states that beginning July 1, 2008, “automatic” (406 MHz) ELTs must be carried on all international operations of both commercial aircraft authorized to carry 19 passengers or less and private aircraft of any number of passenger seats that obtain their certificate of airworthiness after that date. International operations of commercial airplanes authorized to carry more than 19 passengers and that obtain their certificates of airworthiness after July 1, 2008, would have to be equipped with at least two ELTs, one of which must be a 406-MHz unit. Current ICAO standards call for ELTs only on airplanes operated on extended over-water flights and on flights over designated land areas.
