are employed, the light fixtures may be located on the grass shoulder just beyond the declared runway width. Runway Edge Lighting is white except in the following instances: (a) Caution Zone Lighting: On ILS equipped runways without centre line lighting; Yellow edge lighting is installed on the upwind 600 m or one third of the lighted runway length available, whichever is the less. The Yellow 'caution zone' so formed gives a visual warning of the approaching runway end. (b) Pre-threshold Lighting: Where a landing threshold is displaced, but the pre-threshold area is available for the takeoff run, the lights between the beginning of the runway pavement and the displaced threshold show red from the approach. Pilots taking off in such a situation would see red edge lights up to the green threshold then edge lights beyond. Where a starter extension, narrower than its associated runway is provided, blue edge lighting is normally used to mark the edges. (c) Runway Exit Lighting: One or two omnidirectional blue lights may replace or supplement the edge lights in order to indicate an exit taxiway. (d) Stopway Lighting: Where stopway is provided at the end of a runway, the declared stopway is delineated by red edge and end lighting showing only in the direction of landing. A stopway is provided for emergency use only and is not normally suitable for routine use. Taxiway Lights Taxiway lights are depicted in Figure 1.10. Taxiway edge lights are blue in colour. However, centre line taxiway way lights are green in colour. (c) UPES, Not for Reproduction/ Sale

Approach lights greatly increase a pilot's chances of seeing the runway and making a safe landing. Varieties of approach lighting systems based on the centre line and cross bar concept, are in use at aerodromes. These systems range from the simple low intensity centre line and cross bar intended to serve visual runways at night only, to the precision approach lights consisting of centre line and 5 cross bars for day and night use on ILS equipped runways. Simple approach lighting systems (depicted in Figure 1.11) normally commence 500 m prior to the runway threshold whilst the precision approach commences 900 m prior to runway threshold. Where, because of the geography of the approach, it is not possible to install a full system, a shortened system is employed and the Runway Visual Range (RVR) minima associated with the instrument approach procedure adjusted accordingly. Except where supplemented by red side barrettes as described below, approach lighting is white in colour.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
