FIELD: aviation.
SUBSTANCE: invention relates to aircrafts made according to aerodynamic canard and tandem schemes. Aircraft contains two bearing surfaces associated with the fuselage, one of which is provided with a means for regulating the lift, which is functionally dependent on the change in the angle of attack of the aircraft. Both bearing surfaces are rigidly connected to the fuselage. Surface equipped with a means for regulating the lift, which is functionally dependent on the change in the angle of attack of the aircraft, is placed in front of the center of mass of the aircraft. Derivative with respect to the angle of attack of the coefficient of lift of the surface located behind the center of mass, is equal to or no more than twenty times less than the derivative of a similar surface that does not have a means of regulating the lift, depending on the change in the angle of attack.
EFFECT: invention is aimed at ensuring longitudinal stability and simplifying aircraft production technology.
