Airport Lighting Runway Edge Lights Single row of white lights bordering each side of runway and lights identifying the runway threshold Three Intensity Levels: High Intensity (HIRLs), Medium Intensity runway lights (MIRLs), and Low intensity runway lights (LIRLs) Some are Pilot Controlled, some ATC controlled Runway End Identifier Lights (REILS) High intensity white strobe lights placed on each side of the runway to mark the threshold Runway Lights White Taxiway Lights Blue

Runway Edge Lighting Designed to identify the edge of the usable runway surface at night and during periods of low visibility. Clear (or white) except the last 2000’ of a precision or non-precision instrument runway, lights are amber.

Taxiway Edge Lighting Designed to identify the edge of the usable taxiway surface at night and during periods of low visibility. Taxiway edge lighting is blue.

Runway Centerline Lighting Runway Centerline lighting is used to provide pilots with alignment guidance during takeoff and landing operations, primarily during low visibility conditions. Runway centerline lights are white (clear). Except the last 3000’ portion. 2000’ of lights are alternating white/red and the last 1000’ are solid red.

Taxiway Centerline Lighting Taxiway Centerline lighting is designed to facilitate ground movement, primarily during low visibility conditions. Taxiway centerline and lead-on/off lights are green.

Elevated Runway Guard Lights (Wigwags) Elevated guard lights are used to identify the holding position for a runway especially at night and during periods of low visibility. Used to enhance the hold bar and elevated signs.

In –Pavement Guard Lights Supplement hold bars and hold position signage to alert pilots or vehicle operators of the holding position, especially during poor weather or periods of low visibility.

Runway End Lights Used to depict the end of the useable runway to aircraft. Arranged in two sets of four lights.

TAXIWAY edges are indicated by Blue lights. Taxiway Lights Edge (Blue) TAXIWAY edges are indicated by Blue lights.

Airfield Lighting RUNWAY edges are indicated by White lights, followed by Amber and then Red as you move closer to the end of the runway. 20

Visual Glideslope Indicators Pulsating Approach Slope Indicator

View of VASI from approach. Visual Approach Slope Indicator (VASI) The VASI is a system of lights on the side of an airport runway that provides visual descent guidance information during the approach to a runway View of VASI from approach.

Standard VASI system viewed from approach. Consist of two sets of lights Each set designed to appear either white or red depending on angle viewed. If on “Glide Slope”, first set of lights will appear white and second set red. If “High on Glide Slope”, both appear white. If “Low on Glide Slope”, both appear red. Most common type of VASI system Standard VASI system viewed from approach.

Precision Approach Path Indicator (PAPI) On glidepath when two white and two red lights are viewed. If high more white lights will be visible. If low more red lights will be visible. A light system that consists of two, three, or four boxes of lights that provide a visual indication of an aircraft’s position on the glidepath. Depending on the angle, lights will appear red or white. Precision Approach Path Indicator (PAPI)
