Abstract

A wind shear detector provides an alert to the pilot of an aircraft upon the occurrence of a sustained low-level increasing performance shear if the shear occurs for a sufficiently long period of time, even if the shear is of a relatively low magnitude. An integrator is provided to integrate signals representative of low-level increasing performance shears and to provide the alert if the accumulated energy caused by the shear exceeds a predetermined level. The integrated low-level shear signal may be combined with currently occurring shear signals and the alert generated if the combination of current increasing performance shear signals and the integrated shear signal exceeds a predetermined level.
