switch is ONo   Has no influence on stick shaker logic

Each cowl anti-ice valve is electrically controlled and pressure actuated. Positioning the ENG ANTI ICE switches to ON: • allows engine bleed air to flow through the cowl anti-ice valve for cowl lip anti-icing • sets stall warning logic for icing conditions.
