The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes and canards ) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator .
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.
The elevator is a moveable part of the horizontal stabilizer, hinged to the back of the fixed part of the horizontal tail. The elevators move up and down together. When the pilot pulls the stick backward, the elevators go up. Pushing the stick forward causes the elevators to go down. Raised elevators push down on the tail and cause the nose to ...
A tailplane usually has some means allowing the pilot to control the amount of lift produced by the tailplane. This in turn causes a nose-up or nose-down pitching moment on the aircraft, which is used to control the aircraft in pitch. Elevator: A conventional tailplane normally has a hinged aft surface called an elevator,
The rear section of the tailplane is called the elevator, and is a movable aerofoil that controls changes in pitch, the up-and-down motion of the aircraft's nose. In some aircraft the horizontal stabilizer and elevator are one unit, and to control pitch the entire unit moves as one. This is known as a stabilator or full-flying stabiliser. [1] [2]
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).
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.

A drawing the intended locations of plant items and service routes in such detail as to indicate the design intent. The main features of detailed design drawings should be as follows: Plan layouts to a scale of at least 1:100. Plant areas to a scale of at least 1:50 and accompanied by cross-sections.
