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 VGSI's: 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)In the United States, the Federal Aviation Administration includes VGSI information in its Airport/Facility Directory publication. The VGSI, if installed, is listed immediately after each runway and is coded to indicate the type and specific implementation. For example, Chicago Executive Airport (KPWK) located in Wheeling, IL has runway 16. In the A/FD, after runway 16 is listed \"PAPI(P4L)\" which is a PAPI of four (4) identical light units placed on left side of runway. The various VGSI codes and their descriptions can be found in the \"VISUAL GLIDESLOPE INDICATORS\" section of the A/FD's directory legend."@en }
