The GRND PROX FAIL indicator / switch illuminates when activated by an external warning signal from the GPW system. The WIND SHEAR INOP indicator / switch illuminates when activated by an external warning signal from the Wind Shear Warning system. The FLAP OVERRIDE toggle switch is covered by a red protective guard (in the NORM position) to prevent inadvertent inhibition of Mode 4 warnings.
