The 737 MAX family includes design updates, such as the Boeing Advanced Technology winglet, that reduce fuel use and CO2 emissions by at least 14 percent compared to Next-Generation 737s. Other design changes are LED landing, taxi and runway lights and a redesigned electronics bay.
The 737 MAX improved on Next-Generation 737 range with the capability to fly more than 3,500 nautical miles (6,510 km), an increase of 340-570 nmi (629-1,055 km). The 737 MAX also incorporates the latest quiet engine technology to reduce the operational noise footprint of the airplane by up to 40 percent.
Continuous improvement, safety and reliability
The 737 family has long been a pioneer in implementing safety and reliability improvements.
By diligently working with airlines and regulators, Boeing has developed and implemented thousands of safety and efficiency improvements on the 737 family. As a result, its safety record has improved with each generation of models.
The 737 is also extremely reliable. As of February 2019, the three-month average for schedule reliability for all variants of the Next-Generation 737 family was 99.7 percent, meaning 99.7 percent of all Next-Generation flights are ready to depart within 15 minutes of schedule. Schedule reliability for the 737 MAX family was 99.5 percent as of February 2019.
