Wire Marking - Civil Aviation Authority Policy
The Civil Aviation Authority has determined a policy for addressing the risk of wire strike by aircraft. The policy will require pylon-mounted electronically activated visual warning systems, reinforced by audio warning to pilots through VHF radio, to be fitted to high risk wires. This policy will apply to all wires (not just power lines) but not to obstacles generally.
To give effect to this policy, an amendment to the New Zealand Civil Aviation Rules, Part 77, would be required. The amendment will be included for consideration in the rules programme for 2009/10.
The proposed amendment would include a requirement for owners of wires that meet certain criteria in relation to the physical characteristics of the supporting structure – span, height of a tower, and height of a wire at the centre of a span – to notify the Director. The notification would be required in respect of existing wires, or if there is an intention to alter or erect new wires.
Upon receipt of notification the Director would undertake an aeronautical study based on navigability (including span length and height and previous wire strikes), traffic density and visibility to determine whether the risk is high, medium, or low. Indicative criteria, to determine the level of risk, have been developed but these will be further refined and formalised, in consultation with the aviation industry, as part of the rules development process.
A wire deemed by the Director to be “high risk” would be required to be fitted with a warning system that meets the prescribed standard of visual and audio warning broadcast.
The policy stems from initial work undertaken four years ago by the CAA, during which interested parties were consulted. Further consultation will take place as part of the rules development process, including whether the policy proposed by the CAA is a priority for rules development next year.
