A new FAA program is intended to improve the use of comprehensible English as the international language of aviation and support new English language proficiency standards that are scheduled to go into effect in two years. International Civil Aviation Organization (ICAO) member states must âadopt, and controllers and aircrews must conform to and achieve, new English language proficiency standardsâ by March 2008. According to ICAO, âimposition and enforcementâ of the new provisions âwill improve aviation radio and telephone communications in English and therefore enhance aviation safety worldwide.â
