Steering wheel height of the aircraft - aerodynamic control of the aircraft, which rotates around the transverse axis.

The elevator is a deflected aerodynamic surface located in a stream of air flowing around the aircraft. By deflecting the elevator, an aerodynamic force arises that generates a moment of force relative to the center of gravity of the aircraft, and in consequence a change in pitch angle. In the classical aerodynamic scheme, the elevator is performed by a single structural element with a horizontal stabilizer (or simply a stabilizer). There are several types of elevator layout, depending on the layout of the aircraft.

Thus, when classical Scheme elevator is located in the tail of the plane. If you use the scheme "duck"The elevator is located in the front, near the nose plane. There are variations of aerodynamic configuration of the aircraft and without elevator in such cases it replace elevons or other surface. It should be noted that the elevator has never placed too close to the center of gravity of the aircraft that would have caused the need for very large area of ​​the elevator, and as a consequence and weighting control wiring. The elevator is made of longitudinal and transverse stiffeners (ribs, spars and stringers) and fitted by plating (metal sheets, fabrics, composite materials).

It will be understood that when a deviation of the elevator direct height change occurs, a change in the pitch angle of the aircraft as a result of change in the angle of attack and after the variation (increase) of wing lift height change occurs. But the rise is accompanied by a drop in the speed of the aircraft, which should not fall below the minimum stall speed, otherwise the aircraft can get into a tailspin, which in many cases leads to ruin.
In case of insufficient speed, only a change in the pitch angle can occur, without gaining altitude.
