Visual Glide Slope Indicator or Visual Glideslope Indicator (VGSI) is a ground device that uses lights to assist a pilot in landing an airplane at an airport. The lights define a vertical approach path during the final approach to a runway and can help the pilot determine if the airplane is too high or too low for an optimum landing. There are several different types of VGSIs: Visual Approach Slope Indicator (VASI)Precision Approach Path Indicator (PAPI)Pulsating Visual Approach Slope Indicator (PVASI)Three-color Visual Approach Slope Indicator (T-VASI)Helicopter Approach Path Indicator (HAPI)
