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.
The scheduled flight departed from Melbourne as planned at 22:30 using runway 16, which was 3,657 metres (11,998 feet) long. The captain ordered the first officer to rotate 1,043 metres (3,422 ft) before the end of the runway, travelling at a speed of 270 km/h (146 kn; 168 mph). [2]

September 4 – Defense forces public air display, Flemington Racecourse, Melbourne, Australia. A Royal Australian Air Force Vultee Vengeance became inverted at low level after pulling up from a mock bomb dive and went out of control. The aircraft crashed in a nearby industrial suburb, setting fire to a grain mill and narrowly missing a nearby ...
A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero. [4]
The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim ...
5 position trim system. A variable-position horizontal stabilizer changes the pitch simultaneously with the flaperon setting. Normally the horizontal stabilizer also known as tailplane is fixed and has a hinged elevator, a stabilator is another method that combines the functions of an elevator and a horizontal stabilizer.
A Gyroscopic stabilizer is a control system that reduces tilting movement of a ship or aircraft. It senses orientation using a small gyroscope, and counteracts rotation by adjusting control surfaces or by applying force to a large gyroscope. It can be: Some active ship stabilizers adjust "active fins" of the ship or apply force to a large ...
