Either after a landing or on the way to takeoff, pilots must maneuver the aircraft on the ground on a system of taxiways to and from the terminal and hangar areas. airport taxiway lights systems are provided for taxiing at night and also during the day when visibility is very poor, particularly at commercial service airports

The following overall guidance should be applied in determining the airport taxiway lights , marking, and signing visual aid requirements for taxiways:

• In order to avoid confusion with runways, taxiways must be clearly identified.
• Runway exits need to be readily identified. This is particularly true for high-speed runway exits so that pilots can be able to locate these exits 1200 to 1500 ft before the turnoff point.
• Adequate visual guidance along the taxiway must be provided.
• Specific taxiways must be readily identified.
• The intersections between taxiways, the intersections between runways and taxiways, and runway-taxiway crossings need to be clearly marked.
• The complete taxiway route from the runway to the apron and from the apron to the runway should be easily identified.

Runway lights that support CAT II/CAT III must be

• Remotely monitored, or
• Visually inspected prior to the start of CAT II/CAT III with repeated visual inspections/pilot reports every 2 hours while in CAT II/CAT III
• No 2 adjacent lights inoperative
• Lights not below normal brightness
• Lights not obscured by snow, ice, dirt, etc.
• No more than 10% of lights inoperative

Inspection Checklist

• Installed correctly
• Properly oriented
• Operational at all intensities
• Frangible mounts/disconnect plug
• Clean, undamaged lenses
• Uniform intensity
