The Boeing 737 jets are the most popular commercial airplanes in the world. Boeing’s “Original” 737 models are the 737-100 and the 737-200 variations. The “Classic” 737 models are the 737-300, 737-400, and the 737-500.
Boeing‘s most recent line of 737 jets is the 737-600, 737-700, 737-800, and the 737-900, all known as “Next Generation” 737s. These jets incorporate the latest technology, some of which is under constant development and testing. Next Generation features include wingtip extensions known as blended winglets that create added lift, making it possible to carry more weight. They help to minimize engine maintenance and extend the airplane’s range while also saving on fuel costs.
Boeing’s newest 737 jet is the 737-900ER, an extended range variant of the 900 series. The 737-900ER incorporates a number of high-tech features, some of which were originally developed for the United States military.
One example is the Heads-Up Display (HUD) that displays relevant information onto the pilot‘s field of vision, as well as the Enhanced Vision System (EVS), which uses infrared, or thermal, imaging to visually enhance objects that may be difficult for the pilot to see, such as terrain or other airplanes when flying in darkness or bad weather.
The Quiet Climb System (QCS) is another feature of the 737-900ER. The QCS reduces engine noise and gives operators the option of loading more cargo or passengers. It also allows airplanes to operate within local noise restriction airspace.
