Aircraft Navigation (Obstruction Aids)


Types and Uses
The type and arrangement of all aircraft navigation (obstruction aids) i.e. aircraft warning lights (solar or LV powered), solar arrays, batteries and aircraft warning spheres shall be approved by the 
Employer.
Reference is made to Annex 15-1 for the detailed specific requirements.

Design
All aircraft navigation (obstruction aids) shall be so designed as to:
(a) Withstand the mechanical loads relevant to the installation-service-maintenance conditions and 
environmental effects;
(b) Minimize the number of parts and the possibility of incorrect assembly and installation;
(c) Ensure that individual components are secured against becoming loose in service; all threaded 
fasteners shall be locked;
(d) Utilize materials which have sufficient strength, ductility and environmental resistance to 
withstand the static dynamic loading;
(e) Avoid damaging the earthwire under all service conditions;
(f) Comply with the requirements of ICAO Aerodromes Annex 14 Volume 1 Aerodrome Design and 
Operation and Aerodrome Design Manual Part 4 unless stated to the contrary

Night Marking Red Obstruction Light System for Transmission Tower

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. Red obstruction lights are used to increase conspicuity during nighttime. The red obstruction light system is composed of flashing omnidirectional lights (L-864) and/or steady-burning or flashing (L-810) lights. When one or more levels are comprised of flashing lights, the lights should flash simultaneously 1. Single Obstruction Light. A single red obstruction light (L-810) may be used when more than one obstruction light is required either vertically or horizontally, or when maintenance is needed, and can be installed within a reasonable time. Top Level. A single steady-burning light (L-810) may be used to identify low structures, such as airport instrument landing system buildings, as well as long horizontal structures, such as perimeter fenc...

High-voltage lines are major hazards for low-flying aircraft. Placing beacons on pylons is not sufficient to ensure safety due to the very long spans of cable. - Day Marking The warning ball for high voltage lines is a visual anti-aircraft protection for overhead wires and OPGW wires in high voltage transmission lines. It is recommended that in the case of a sphere with a diameter of 60 cm, the high-voltage line should be marked every 30 meters at the most. - Night Marking Conductor marking lights serve as a specialized category of aircraft warning lights specifically crafted for overhead power lines. In contrast to overhead wire markers that rely on daylight, conductor marking lights are designed to be visible during nighttime. These lights enhance the visibility of transmission line catenary wires in the vicinity of airports, heliports, and locations spanning across rivers. It is built around induction and takes its power from the current of the line, by the intermediary of a multi-winding coil directly installed within the beacon. This allows our system to adapt to every line voltage.

Overhead Wire Marker Fiberglass Aircraft Warning Sphere Day Marking  Aerial Marker Balls for High Voltage Power Lines  Warning sphere is used for warning aircraft pilots in daytime and nighttime, which is compliant with International Civil Aviation Organization (ICAO) recommendations annex 14 chapter 6. It can be used in overhead cable, guyed wire, especially in extra high voltage power transmission line, cross river power transmission line, cross road, bridge power transmission line and so on. It is made of high-grade polyethylene with the color of red, orange, white. Different colors' warning sphere should be displayed alternately. If there are many lines, warning sphere should be displayed on the highest line. It can resistant to corrosion, rust, water, dust, high temperature, can be used for long time.
