Boeing is advancing towards certification and service entry of the latest 737
Boeing launched the 737 MAX on August 30, 2011. The company was the second of the dominant players in the narrow body segment of the airliner market to launch a new version of a proven product, after Airbus in December 2010 launched the rival A320neo (new engine option).
Three main versions of the 737 MAX were launched: the MAX 7, MAX 8 and MAX 9, succeeding the 737-700, 737-800 and 737- 900ER respectively. The MAX 8 would be the first variant to be developed. A fourth variant, the MAX 200, a high-density variant of the MAX 8, was announced in 2014. All four will feature a range of technologies, spearheaded by a new generation of more efficient CFM International LEAP-1B engines, to provide double-digit reductions in fuel burn and emissions, as well as lower noise and operational costs.
