737 MAX split-tip winglet. The McDonnell Douglas MD-11 was the first aircraft with split-tip winglets in 1990. For the 737 Next Generation, third-party vendor Aviation Partners has introduced a similar design to the 737 MAX wingtip device known as the split scimitar winglet, [34] with United Airlines as the launch customer.

The Split Scimitar design as seen at Denver International Airport on a Boeing 737 of Southwest Airlines. APB's Split Scimitar Winglet retrofit program consists of retrofitting 737NG's winglets by replacing the aluminum winglet tip cap with a new aerodynamically shaped "Scimitar" winglet tip cap and by adding a new Scimitar tipped ventral strake.
A split-tip wingtip was first proposed for the McDonnell Douglas MD-12, a 1990s twin-deck aircraft concept. [133] A MAX 8 with 162 passengers on a 3,000-nautical-mile (5,600 km; 3,500 mi) flight is projected to have a 1.8% lower fuel burn than a blended winglet -equipped aircraft (like many 737NG aircraft) and 1% lower over 500 nmi (930 km; 580 ...

In 2011, Boeing launched the 737 MAX, an updated and re-engined version of the 737NG with more efficient CFM International LEAP-1B engines, and aerodynamic changes with distinctive split-tip winglets. [33] The first 737 MAX performed its first flight in January 2016. [34] The fourth generation 737 MAX supersedes the third generation 737NG.
Multiple accidents involving Boeing’s 737 Max 9 planes have kept the corporation in the news and under Federal Aviation Administration (FAA) investigation.
Aircraft may have additional minor aerodynamic surfaces. Some of these are treated as part of the overall wing configuration: Winglet: a small fin at the wingtip, usually turned upwards. Reduces the size of vortices shed by the wingtip, and hence also tip drag.
Outboard tail. An outboard tail is located outboard of the main wing tips. Although sometimes described as tailless, the outboard tail configuration differs from a tailless wing in that the horizontal stabilizer is discontinuous from the main wing surface, typically being set further back and requiring a short boom to support it.
