Abstract The paper deals with the automatic roll angle of the control channel of the aircraft, built on the airplane assembly scheme. This channel is needed to stabilize a zero roll and, moreover, is the main component of the direction of automatic flight control systems of aircraft under consideration. We investigate the functioning of the bank channel in a more Ask effects needed to perform bends with large transverse accelerations and maneuver to "flip", allowing to quickly change the flight direction is reversed, provided that the aircraft allows great overload in the basic position, inverted and - operating significantly less congestion. In addition to defining a large impact, it is assumed that the aircraft are short-term impact type perturbation, the consequence of which is to create the initial conditions for the angular orientation and angular velocity. In operation, the channel autopilot roll at large disturbance is not possible to consider the control loop as a line. In this case it is necessary to consider restricting the aileron tabs and frequency characteristics of the roll angle sensor. The need to incorporate said non-linearities caused by the fact that at high initial angular aircraft speeds, even when fully efficient aileron tab can make several revolutions about the longitudinal axis of the associated coordinate system to the point in time when the kinetic energy of rotational motion will be mainly extinguished and begin forming a predetermined angle of heel. In studies considered the time constant aileron actuator, which is 2.3 times and 4 times less constant aircraft roll. The automatic system is considered when the stability margin of phase 630 , 400 and 200 . Studies have shown that the automatic control system of the roll angle when the phase margin 630 allows testing of the corners, which do not exceed 1660 . Thus, the transverse overload when performing a coordinated turn may exceed 9. It is possible to maneuver with the "flip", allowing quickly change the flight direction is reversed
