The aircraft is slightly below the glideslope. A precision approach path indicator ( PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. It is generally located on the left-hand side of the runway approximately 300 meters beyond the landing threshold of ...
The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.
Visual Glide Slope Indicator. 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 ...
Aviation light signals. A United States Air Force airman with a signal light gun that can be used to control aircraft with radio failure.

Instead, the midsized airliner with 124 passengers on board landed on the Downtown Airport runway, which is half as long as the Branson runway. The runways are oriented in a similar direction.
Runway edge lighting are used to outline the edges of runways during periods of darkness or restricted visibility conditions. These light systems are classified according to the intensity they are capable of producing: Many HIRL and MIRL systems have variable intensity controls, whereas the LIRLs normally have one intensity setting. At airports ...
Runway Status Lights ( RWSL) are a visual alerting system installed in some airport taxiways and runways for the purpose of collision-avoidance. When illuminated, red high-intensity LEDs indicate the presence of another vehicle either departing, occupying, or landing on an active runway. RWSL systems are fully-automated and intended to alert ...
