It would generate unnecessary drag as the aspect ratio of an engine nacelle is lousy. ![]() The nacelles are designed to not generate lift in normal flight. When flying at normal angles of attack (3° at cruise and say 5° in a turn) the destabilizing effect of the larger engines are not felt. The larger nacelles, called for by the higher bypass LEAP-1B engines, changed this. Once the aircraft entered a stall, there were several actions described last week which assisted the pilot to exit the stall. Until the MAX, there was no need for artificial aids in pitch. Once such area is the artificial yaw damping, present on virtually all larger aircraft (to stop passengers getting sick from the aircraft’s natural tendency to Dutch Roll = Wagging its tail). ![]() ![]() It relies on a naturally stable base aircraft for its flight control design, augmented in selected areas. The 737 is a classical flight control aircraft. The 737-800 (yellow) overlaid on the 737 MAX 8 (purple), with the line denoting the CG in pitch.
