The Boeing 737 MAX, the latest generation of the iconic 737 series, features significant changes compared to its predecessor, the 737 Next Generation (NG). One notable difference is the taller landing gear struts. The reason for this change lies in accommodating larger and more powerful engines while maintaining sufficient ground clearance.
Boeing has aimed to retain commonality with previous models to avoid requiring a new type rating. This decision helps airlines save costs on pilot training and maintenance. According to Boeing, "Because of the 737’s popularity with airlines everywhere around the world, integrating the new 737 MAX is an easy proposition."
The engines used in the 737 MAX are CFM LEAP-1B turbofan engines, which offer increased thrust and reduced emissions compared to earlier models. Safran Aircraft Engines highlights that these engines provide "15% lower" fuel consumption and CO2 emissions and up to "50% lower" NOx emissions.
