The Boeing 737 is an American narrow-body airliner produced by Boeing at its Renton factory in Washington. Developed to supplement the Boeing 727 on short and thin routes, the twinjet retained the 707 fuselage width and six abreast seating but with two underwing Pratt & Whitney JT8D low-bypass turbofan engines.
t. e. The Maneuvering Characteristics Augmentation System (MCAS) is a flight stabilizing feature developed by Boeing that became notorious for its role in two fatal accidents of the 737 MAX in 2018 and 2019, which killed all 346 passengers and crew among both flights. Because the CFM International LEAP engine used on the 737 MAX was larger and ...
Aircraft engine starting. Ground crew disconnecting an air start hose from a Boeing B-52 Stratofortress. Many variations of aircraft engine starting have been used since the Wright brothers made their first powered flight in 1903. The methods used have been designed for weight saving, simplicity of operation and reliability.
The 737 MAX 9 mockup at the 2012 ILA Berlin. Faced with the record orders for Airbus and the defection of a long-time customer, on August 30, 2011, Boeing's board of directors approved the launch of the re-engined 737, which they said would meet or exceed the range of the Airbus A320neo [24] while burning 4% less fuel.

Outdoor engine run up area of the Istanbul Atatürk Airport. The checks performed during a run-up vary with the type of aircraft and (to a lesser extent) with the operating rules under which the flight is being conducted, e.g., instrument flight rules, visual flight rules, operation as a commercial carrier or private pilot, and so on.
The first engines entered service in 1982. The CFM56 was later selected to re-engine the Boeing 737. Boeing initially expected this re-engine program (later named the Boeing 737 Classic) to sell only modestly, but in fact the CFM56's lower noise and lower fuel consumption (compared to older engines for the 737) led to strong sales.
The initial 737-300 (foreground) is 9 ft 5 in (2.87 m) longer than the 737-200 (background) and is re-engined with wider and more efficient CFM56 turbofans. Following the success of the Boeing 737-200 Advanced, Boeing wanted to increase capacity and range, incorporating improvements to upgrade the plane to modern specifications, while also retaining commonality with previous 737 variants.
A Boeing 737-800 retracting its undercarriages during takeoff. In a single-engine or light twin-engine aircraft, the pilot calculates the length of runway required to take off and clear any obstacles, to ensure sufficient runway to use for takeoff. A safety margin can be added to provide the option to stop on the runway in case of a rejected ...
