ABSTRACT:
An aircraft carries a pressure indicator well in advance, which may record barometric pressure of vertical air currents. The indicator reading is converted to electric current and averaged over a short period. The unaveraged current at a given position of the pressure indicator is recorded, delayed, read out, compared with the average current and the error current used to actuate wing flaps at the instant the wings pass over the given position, so as to adjust the wing lift for any difference in conditions as the wings move forward. Similarly the current recorded at the instant the pressure indicator was at a given point is delayed, compared with the average current at the instant the tail structure passes over the given point, and the error current is used to adjust elevators for any difference in pressure as the tail structure moves from its first position to the position of the pressure indicator at the given instant. Negative feedback may be utilized to reduce any error in the positions of the wing flaps and the tail elevator from the positions called for by the error currents.
