Main rules for aircraft warning lights

MAIN RULES FOR VISUAL AIDS
ICAO Annex 14 – Aerodromes Vol. 1 – Chapter 6 / 10 (July 2004)
• The marking and/or lighting of obstacles is intended to reduce hazards to aircraft by indicating the presence of the obstacles
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.1)
• Marking (red-orange/white painting) is used for day time
• Marking may be omitted when the obstacle is lighted
• A fixed obstacle above a horizontal surface should be marked and, if the aerodrome is used at night, lighted.
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.1.4)
• A system of preventive maintenance of visual aids shall be employed to ensure lighting and marking system reliability.
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 10.4.2)
• The reliability of installed lighting equipment should not less than one year.
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 10.4.6)
• The number and arrangement of Low, Medium or High Intensity Obstacle Lights , at each level to be marked, shall be such that the object is indicated from every angle in azimuth
• Where a light is shielded in any direction by another, additional light shall be provided
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.22)
• The number of lights needed for each level depends on the outside diameter of the obstacle
• The top lights should be placed sufficiently below the top, so as to minimize contamination by smoke, powders, and so on.
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.12)

AWL TYPES (Aircraft Warning Lights)
LIOL-A / B Low Intensity Obstacle Lights on fixed objects, Type-A / Type-B, shall be steady burning RED lights
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.23)
MIOL-A Medium Intensity Obstacle Lights on fixed objects, Type-A , shall be flashing WHITE lights
MIOL-B Medium Intensity Obstacle Lights on fixed objects, Type-B , shall be flashing RED lights
MIOL-C Medium Intensity Obstacle Lights on fixed objects, Type-C , shall be steady burning RED lights
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.30)
MIOL-A / MIOL-B Medium Intensity Obstacle Lights Type-A / Type-B, located on an obstacle, shall be flash simultaneously
(ICA: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.32)
HIOL-A / B High Intensity Obstacle Lights on fixed objects, Type-A / Type-B, shall be flashing WHITE lights
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.33)
HIOL-A High Intensity Obstacle Lights Type-A, located on an obstacle, shall be flash simultaneously
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.35)
HIOL-B High Intensity Obstacle Lights Type-B, indicating the presence of tower supporting overhead wires, an others.. shall be flash sequentially
(ICAO: Aerodromes – Annex 14 – Vol. 1 – Ch. 6.3.36)
