ABSTRACT:
The horizontal stabilizer position is provided to the automatic flight control system software where it is passed through a second order Chebychev motion filter to provide horizontal stabilizer rate. A threshold and hysteresis function detects when the motion exceeds 0.08.degree. per second. While the stabilizer motion exceeds the threshold, a displacement detector determines when the stabilizer position has exceeded 1.degree. since the motion was first detected. When the 1.degree. change in position has occurred while the rate was exceeded, a motion flag is transmitted to the warning system. A sign change detector determines when the output of the motion filter changes sign. A holding latch responsive to the stabilizer position and to the threshold and hysteresis function latches the stabilizer position when the 0.08.degree. per second rate is exceeded. The difference between the latched position and the current position is applied to a threshold detector to determine when the difference exceeds the 1.degree. change in position. The sign change detector unlatches the holding latch when the sign of the output of the motion filter changes. The output of the threshold and hysteresis function remains true until the output of the motion filter falls below 0.055.degree. per second.
