Abstract
A system to warn an aircraft pilot of a hazardous wind shear condition in which the rate of change of airspeed is compared to the ability of the aircraft to respond thereto. Any difference therebetween that exceeds a predetermined threshold is used to activate a suitable alarm or compensation device. Additional refinements include correcting the inertial speed inputs for vertical components and autopilot induced throttle changes, and correcting the air speed inputs for short term fluctuations.
Claims4
A system to detect a wind shear condition encountered by an aircraft having a pitot pressure sensing tube for measuring air speed comprising in combination:
- pitot pressure sensing means;
- pressure change measuring means connected to said pressure sensing means operable to produce a signal proportional to the rate of change of pressure in said pitot tube;
- a reference means calibrated to represent the maximum acceleration capability of said aircraft;
- and
- indicating means connected to said pressure change measuring means and said reference means so as to display the signal therefrom relative to the reference means.
