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.

Grumman F-14 Tomcat jet fighter during a takeoff, with stabilators deflected upwards. A stabilator is a fully movable aircraft horizontal stabilizer.It serves the usual functions of longitudinal stability, control and stick force requirements [1] otherwise performed by the separate parts of a conventional horizontal stabilizer (which is fixed) and elevator (which is adjustable).
The horizontal stabilizer is the fixed horizontal surface of the empennage. A tailplane, also known as a horizontal stabilizer, is a small lifting surface located on the tail behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes.
Basic aircraft control surfaces and motion. ... The elevator is a moveable part of the horizontal stabilizer, hinged to the back of the fixed part of the horizontal ...
The probable cause was stated to be "a loss of airplane pitch control resulting from the in-flight failure of the horizontal stabilizer trim system jackscrew assembly's Acme nut threads." [1] For their efforts to save the plane, both pilots were posthumously awarded the Air Line Pilots Association Gold Medal for Heroism.
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. The variable-position horizontal stabilizer is governed by the flaperon setting: the settings of the flaperon control produce corresponding changes ...
Delta Air Lines Flight 1141, a Boeing 727 flying between Dallas-Fort Worth and Salt Lake City on Aug. 31, 1988, crashed shortly after takeoff. Of the 108 on board, two crew members and 12 ...
The new flight control laws now permit only one activation of MCAS per sensed high-AOA event, and limit the magnitude of any MCAS command to move the horizontal stabilizer such that the resulting position of the stabilizer will preserve the flightcrew's ability to control the airplane's pitch by using only the control column.
