A system of airplane instrumentation utilizing devices and procedures for dealing with wind shear on the final approach to a landing. The system is designed for use in a like manner on all approaches for landing to assure that a safe, stable speed be used during all landing approaches, and that the Pilot be apprised of the conditions his airplane is flying through at all times during the approach. The primary aim is to provide instrumentation which will aid the Pilot in achieving safe approach criteria, give him information on which to base his judgment, and eliminate accidents on the final approach due to wind shear.

In the method of controlling the power to be applied to an aircraft engine during a final approach, whether wind shear conditions exist or not, and including the steps: (a) monitoring deviation of actual airspeed from a target airspeed on the approach, and deviation of actual groundspeed from a target approach groundspeed on the approach, and (b) employing such deviations in such a manner so that the approach speed is controlled by whichever of the actual speeds is lower compared to its associated target speed, and using said lower actual speed to control power to maintain a stabilized aircraft speed condition during the final approach, the improvement comprising: (c) utilizing air temperature and pressure data to modify the value of target indicated airspeed thereby to derive a true airspeed value for use as a zero wind groundspeed marker value, (d) displaying said value, and (e) modifying said value as a function of an automatically or manually programmed surface wind velocity along course component to derive an uncompensated value of said target approach Groundspeed, and (f) in the case of a manually programmed surface wind velocity value, correcting said uncompensated value by selecting one of a group of possible percentages of wind component to derive a compensated target approach groundspeed.
