According to the Civil Aviation Regulations which accompany the Civil Aviation Act, the Civil Aviation Safety Authority of Australia (CASA) must be notified of any ‘obstacle’, which may affect aircraft safety. The CASA definition of an obstacle includes any plume which exceeds a vertical velocity of 4.3 m/s. Consequently, plumes emitted by industry in the vicinity of airports and aerodromes must be assessed to determine their potential impacts on aircraft safety. When any plume is determined to exceed the 4.3 m/s safety criterion, a report identifying its spatial and temporal characteristics must be submitted to CASA for assessment and approval.
Mirrabooka Consulting’s senior technical advisor, Dr Tim Scholz has developed a CASA approved methodology for evaluating the variation of plume dynamics with both height above the stack top and with meteorological conditions. Dr Scholz has successfully applied this methodology to many industrial developments including BP Bulwer Island Refinery, Incitec Granulation Plant, Maryborough Sugar Mill Cogeneration Plant, Phillips Petroleum Liquefied Natural Gas Plant and the Australian Army’s Robertson Barracks in Darwin.
