What are the design consideration for a taxiway lighting?
Taxiway Edge Lights The exact spacing is influenced by the physical layout of the taxiways. Straight sections of taxiways generally require edge light spacing in 200-ft intervals, or at least three lights equally spaced for taxiway straight line sections less than 200 ft in length.
What is the purpose of taxiway?
A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities. They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass.

How is taxiway marking done?
Centreline marking consists of a single continuous line marking the centre of the taxiway. Where a taxiway crosses a runway, the Taxiway Centreline Marking indicates the route to be followed but the marking is interrupted as necessary so as not to interfere with the runway markings.

Where are the enhanced taxiway centerline markings located?
Enhanced taxiway centerline markings are used at larger airports to warn pilots that they are approaching a runway holding position marking. These markings consist of two parallel, yellow-dashed lines located on either side of the normal taxiway centerline beginning approximately 150′ before a runway holding position marking.
What do the dashed lines on a taxiway mean?
Dashed Edge Markings These lines define the edge of the taxiway, but allow aircraft to cross them as necessary, for example, to turn onto a parking apron, etc. Dashed taxiway edge markings consist of a pair of broken double yellow lines, with each line being at least 6 inches in width, spaced 6 inches apart. Figure 9.
