Runway Distance Remaining
White lights that outline the edges of a runway during darkness or periods of low visibility.
Runway Edge Lights
Two synchronized, unidirectional flashing lights denoting the end of the runway.
Runway End Identifier Lights (REIL)
Lights in the center line spaced every 50 feet. They start out as white, then alternate between red and white, then are solid red toward the end of the runway.
Runway Centerline Lighting System.
To indicate the touchdown zone in adverse landing conditions, two rows of transverse light bars are installed symmetrically about the runway centerline.
Touchdown Zone Lights
Alternating green and yellow lights are sometimes installed to aid pilots in entering/exiting the runway onto/from the taxiway.
Taxiway Centerline Lead-on/Lead-off Lights.
Pulsing white lights installed across the runway at the hold short point.
Land and Hold Short Lights
Blue light or reflectors used to outline the edge of the taxiway during darkness or low visibility.
Taxiway Edge Lights
Green lights installed along the centerline of the taxiway.
Taxiway Centerline Lights
Three yellow lights to increase visibility of a holding position and to indicate the location of an intersecting taxiway.
Clearance Bars
Installed to point out taxiway/runway intersections. They are a pair of yellow flashing lights on each side of the taxiway. They can be a row of in-pavement yellow lights across the taxiway at marked and signed holding points.
Runway Guard Lights
A row of red lights across the taxiway across the holding position. Air traffic control will turn these lights off and the taxiway lead-on lights on which t issuance of clearance to proceed.
Stop Bars
A lighting system consisting of lighters, sequenced flashing lights, or a combination of the two that lead up to the approach end of the runway.
Approach Lighting System
Typically consists of two light bars located on the left or right side of the approach end of the runway.
Visual Approach Slope Indicators (VASI)
When the farther VASI bars are red and the closer bars are white, this indicates that…
The airplane is properly angled for approach.
When both VASI bars are white, this indicates that…
The airplane is flying too high over the proper glide path.
When both VASI bars are red, this indicates that…
The airplane is flying too low below the proper glide path.
How many miles away are VASI lights visible during the day?
3-5 miles
How many miles away are VASI lights visible at night?
20 miles
What are the three basic types of runways?
Visual Runways
Non-precision Instrument Runways
Precision Instrument Runways
These runways have no lighting and few markings. The pilot must see the ground to land, as the use of instruments is not sufficient for landing.
Visual Runways
These runways can provide horizontal positioning guidance as the airplane approaches.
Non-precision Instrument Runways
These runways have an instrument approach procedure using a landing system that provides both horizontal and vertical guidance.
Precision Instrument Runways
Runways typically in smaller airports.
Visual Runways
Runways typically in small to medium airports.
Non-precision Instrument Runways
Runways typically in medium to large airports.
Precision Instrument Runways
Depending on the surface, these runways can have threshold markings, designators, centerlines, and sometimes an aiming point (approx. 1000 ft from the landing threshold.
Non-precision Instrument Runways
These runways have thresholds, designators, centerlines, aiming points, blast pads, stowaways, and touchdown zone markings.
