Note   Taxiway edge markers must be used in accordance with section 9.79.

9.95 Characteristics of taxiway edge markers

       (1) Taxiway edge markers must be retroreflective blue.

       (2) The surface of a taxiway edge marker, as viewed by the pilot of an approaching aircraft, must be:

(a) rectangular; and

(b) with a height to width ratio of approximately 3:1; and

(c) with a minimum viewing area of 150 cm².

       (3) Taxiway edge markers must be:

(a) lightweight; and

(b) frangible; and

(c) low enough to preserve adequate clearance for propellers and jet aircraft engine pods.

9.96 Taxiway centreline markers

        If taxiway centreline markers are used, such markers must be installed at least in the same locations as taxiway centreline lights would have been installed had such lights been used.

Note   Taxiway centreline markers must be used in accordance with section 9.79.

9.97 Characteristics of taxiway centreline markers

       (1) Taxiway centreline markers must be retroreflective green.

       (2) The marker surface, as viewed by the pilot of an approaching aircraft, must be a rectangle with a minimum viewing surface of 15 cm².

Note   Reflective pavement markers or '"cats-eyes" are typically able to satisfy this requirement.

       (3) Taxiway centreline markers must be able to withstand being run over by the wheels of an aircraft without damage either to the aircraft or to the markers themselves.

9.98 Provision of runway guard lights

Note   Runway guard lights are sometimes referred to as "wig wags".

       (1) Runway guard lights must be provided at the intersection of a taxiway with a runway intended for use in:

(a) visibility conditions less than 550 m, if stop bars are not installed; or

(b) visibility conditions between 550 m and 1 200 m, when the aerodrome traffic density is heavy.

Note 1   An aerodrome that is not required to provide runway guard lights may choose to do so as an aid to reducing runway incursions.

Note 2   CASA recommends that runway guard lights be installed in conjunction with a stop bar.

       (2) If runway guard lights are provided for a runway, they must be installed and used at all taxiways and road access points that allow access to the runway.

       (3) Despite subsection (2), runway guard lights are not required for a taxiway if:

(a) the taxiway is used only for exiting from the runway; and

(b) the taxiway cannot be used for entry to the runway by either aircraft or vehicles.

9.99 Pattern and location of runway guard lights

       (1) Subject to subsection (2), runway guard lights must be either:

(a) elevated runway guard lights on each side of the taxiway (Configuration A); or

(b) in-pavement runway guard lights across the taxiway (Configuration B).

       (2) Both elevated and in-pavement
