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. Not all fixed-wing aircraft have ...
Supersonic aircraft usually have all-moving tailplanes (stabilators), because shock waves generated on the horizontal stabilizer greatly reduce the effectiveness of hinged elevators during supersonic flight. Delta winged aircraft combine ailerons and elevators –and their respective control inputs– into one control surface called an elevon.
Furthermore, the empennage of the An-225 was a twin tail with an oversized, swept-back horizontal stabilizer, having been redesigned from the single vertical stabilizer of the An-124. The use of a twin tail arrangement was essential to enable the aircraft to carry its bulky external loads that would generate wake turbulence , disturbing the ...
The aircraft are designated Gulfstream GVII-G500 and GVII-G600 in their type certificate. [9] The two larger models were unveiled on October 14, 2014 and the smaller G400 was unveiled on October 4, 2021. The G500 was first delivered on September 27, 2018, and the longer G600 was first delivered August 8, 2019.
There have been 2,751 aircraft crashes with a fatality in Texas in more than 50 years, ... the safety board discovered that missing screws on the horizontal stabilizer led to the crash.
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 ...
