This Standard specifies requirements for marking of overhead cables and their supporting structures
for visual warnings to pilots of aircraft involved in planned legal low-level aviation operations.
Typical aviation operations within the scope of this Standard include aerial application, firefighting,
mustering, emergency services response, power line inspection, survey, media, parachuting and
ballooning operations conducted under an approval, licence or regulations issued by the Civil Aviation Safety Authority (CASA).
Aircraft warning markers specified in this part of the Standard are designed as a visual reminder of the location of the cables and their supporting structures.
The landholder, pilot, pilot representative or aviation operations entity conducting the operation will
endeavour to identify relevant hazards, including overhead cables and their supporting structures,
before commencing the operation.
This Standard does not apply to low level flying as a result of an operational emergency (see definitions of planned low level legal aviation operations).
