WIND SHEAR DETECTION AND ALERTING SYSTEM

摘要

an early warning system for detecting wind shear (30) compares accelerations derived by inertia (32, 34) at a speed of the air (52) to provide an alarm signal due to wind shear. as acceleration is derived are used instead of purely inertial accelerations because of purely inertial systems generally require a autogyre vertical.by using an angle (alpha) and a flight path angle (gamma) instead of the signal of tanguage () in the vertical autogyre calculation, no signal is required and the system is sensitive to both the vertical and horizontal shear conditions.in an improved version of the system, there is also provided a compensation taking into account the roll angle (o), the roll angle is derived from the rate of change (psi) to avoid the need to use a autogyre vertical.the warning system is able to provide audio and visual alarms for a variety of wind shear conditions such as shear, shear line, shear line shear head tracking and the trend of wind shear.the alarm system is also capable of generating an alarm of wind shear, which is a function of the radio altitude (112) of the aircraft.
