Seeing the Runway LightingApproach and Runway Lighting need to be clearly defined, with other lighting not causing a distraction

ALS = Approach Lighting System, consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway.

PAPI = Precision Approach Path Indicator – 4 red/white lightsStart of runway = Threshold - Line of green lights

FEATURES• Fixture rises a maximum of 0.250 inch above the surface finish.• Light fixture is a uni-directional fixture with two (2) 48-watt halogen lamps.

USEThe Honeywell Runway End Lights are used to define the end of the runway pavement suitable for aircraft operation. The lights are typically used with medium and high intensity approach lighting systems utilizing displaced thresholds. Prisms are non-field replaceable.

Taxi Way Lighting

ZELION LED modules have been developed specifically for the complex set of requirements that have to be met in airfield lighting applications.

Halogen lamps are the perfect light source for airfield lighting. Light sources for this application need to be highly reliable, durable and have relatively low installation costs – properties that define halogen lamps from OSRAM. They provide instant and constant light output and have an impressively long life of up to 6000 hours. The light from halogen lamps is absolutely flicker free and dimmable, providing first-class performance even in adverse weather conditions such as snow and fog. Thanks to their small size and high luminance these lamps are ideal for the compact design of airfield lights. OSRAM offers halogen lamps with wattages from 30W to 200W with or without a reflector

Air Navigation: The Order and the RegulationsCAP 393 Lighting of en-route obstacles219 (1) The person in charge of an en-route obstacle must ensure that it is fitted with mediumintensity steady red lights positioned as close as possible to the top of the obstacle andat intermediate levels spaced so far as practicable equally between the top lights andground level with an interval of not more than 52 metres. 8) In this article, an ‘en-route obstacle’ means any building, structure or erection, theheight of which is 150 metres or more above ground level.

Aircraft Landing Lights

CAP393 Air Navigation:The Order and RegulationsLights liable to endanger221 (1) A person must not exhibit in the United Kingdom any light which:(a) by reason of its glare is liable to endanger aircraft taking off from or landing at anaerodrome; or(b) by reason of its liability to be mistaken for an aeronautical ground light is liable toendanger aircraft.(2) If any light which appears to the CAA to be a light described in paragraph (1) is exhibited,the CAA may direct the person who is the occupier of the place where the light isexhibited or who has charge of the light, to take such steps within a reasonable time asare specified in the direction:(a) to extinguish or screen the light; and(b) to prevent in the future the exhibition of any other light which may similarlyendanger aircraft.

7.8.2 Lighting in the vicinity of aerodromes

7.8.2.1 General

NOTE 1 The Civil Aviation Act 1982 [45], Section 105 specifically defines an aerodrome as any area of land or water designed, equipped, set apart or commonly used for affording facilities for the landing and departure of aircraft and includes any area or space, whether on the ground, on the roof of a building or elsewhere, which is designed, equipped, and set apart for affording facilities for the landing and departure of aircraft capable of descending or climbing vertically.

NOTE 2 Attention is drawn to the Air Navigation Order 2000 [46], Article 110 inrespect of lights that might affect aircraft. A light can endanger aircraft when:a)the intensity causes glare in the direction of an approaching aircraft;

b) the colour (e.g. advertising signs) causes it to be mistaken for an aeronautical light;

c) viewed from the air, lights make a pattern (e.g. a row of street lights) similar to an approach or runway lighting pattern;

d) the overall amount of illumination near the approach to a runway detracts from the effectiveness of the visual aids provided by the aerodrome for use byaircraft, particularly in poor visibility conditions.Road lighting can present a hazard due to the effect of lighting upon the pilot’svisual picture or due to the creation of physical obstacles within the airspacemanoeuvring area around the aerodrome. A road lighting scheme couldprejudice the safe movement of aircraft on either or both grounds. Each issueshould be addressed separately and appropriate measures taken to minimize any hazards identified.
