In 2011 World Bank and the government of Tuvalu agreed to commence the Tuvalu Aviation Investment Project (TvAIP) for the purpose of improving operational safety and oversight of international air transport and associated infrastructure at Funafuti International Airport. In November 2013 the World Bank approved US$6.06 million in finance for the TvAIP. Further World Bank funding was provided in 2017. TvAIP is intended to improve the runway so that it achieves a minimum pavement classification number (PCN) of 18 to provide a load-carrying capacity of the pavement that rates the runway for emergency flights. TvAIP also involved improvements of navigational aids and other safety and security facilities to meet International Civil Aviation Organization (ICAO) requirements.
