Taxiway - Taxiway Lights

Taxiway Lights

For night operations, taxiways at many airports are equipped with lights, although some small airports are not equipped with them.

• Taxiway Edge Lights: used to outline the edges of taxiways during periods of darkness or restricted visibility conditions. These fixtures are elevated and emit blue light.
• Taxiway Centerline Lights: They are steady burning and emit green light located along the taxiway centerline
• Clearance Bar Lights: Three in-pavement steady-burning yellow lights installed at holding positions on taxiways
• Runway Guard Lights: Either a pair of elevated flashing yellow lights installed on either side of the taxiway, or a row of in-pavement yellow lights installed across the entire taxiway, at the runway holding position marking at taxiway/runway intersections.
• Stop Bar Lights: A row of red, unidirectional, steady-burning in-pavement lights installed across the entire taxiway at the runway holding position, and elevated steady-burning red lights on each side used in low visibility conditions (below 1,200 ft RVR). A controlled stop bar is operated in conjunction with the taxiway centerline lead-on lights which extend from the stop bar toward the runway. Following the ATC clearance to proceed, the stop bar is turned off and the lead-on lights are turned on.

Taxiway edge lights are spaced 75 feet apart. These lights can be closer together at taxiway intersections. On straight segments, Taxiway Centerline Lights are spaced at either 50 or 100 foot intervals depending on the minimum authorized visibility. On curved taxiway segments, Taxiway Centerline Lights may be required to be closer together.
