METHOD FOR AUTOMATIC CONTROL OF AIRCRAFT AT APPROACH TO RUNWAY LINE Russian patent published in 2004 - IPC

FIELD: aviation instrument making.

SUBSTANCE: the method consists in normalization of signals of the preset heading and linear range to the tangency point of the preset outlying circumference in the co-ordinate system bound with the runway, normalization of a signal of the programmed altitude value, normalization of normal g-load control signals, normalization of a bank control signal, normalization of aircraft attitude variation control signals. In addition a signal of critical range to the tangency point of the outlying circumference depending on the values of the heading, minimum possible turn radius and the radius of the preset outlying circumference is normalized. The control signal of the preset bank angle from the moment of coincidence of the value of the linear range signal to the tangency point of the outlying circumference with the value of the critical range signal is normalized. As soon as the signal of linear range to the tangency point of the new outlying circumference with a radius equal to the minimum possible turn radius becomes equal to zero flattening-out of the aircraft takes place in the runway line.

EFFECT: enhanced accruacy of the formed aircraft trajectory.
