1. Project AS 06/07 Assessment of obstacles including wind turbines and exhaust plumes
Project closure notes
Project closed 1 March 2011
Project overtaken by events. AC 139-18(0) Obstacle Marking and Lighting of Wind Farms was withdrawn September 2009 after CASR 139 (Aerodromes) was found not to be applicable to areas located away from aerodromes regulated under CASR 139. CASA embarked on a review of the risk to aviation by wind farms located away from aerodromes and a consultants report outlining proposed recommendations was finalised in late 2009 but no further action was taken. The Department of Infrastructure and Transport is currently addressing the impact of wind farms on aviation which they raised in the paper “Safeguards for Airports and the Communities around them”.
Advisory Circular – AC139-05(0) Guidelines for conducting plume rise assessments, June 2004 is currently being reviewed by Office of Airspace Regulation in terms of the critical plume rise velocity, plume rise modelling and critical height of plume rise, with the aim of producing a revised AC.
Purpose/Objectives
The increasing incidence of windfarm proposals and higher stack velocities is creating confusion and contradictory CASA responses. Existing advisory material for CASA’s assessment of windfarms, exhaust stack plumes and obstacles in general is not adequate in defining a risk-based assessment process.
This project sets out to provide clear, unambiguous guidance to the community and CASA staff for risk assessment of possible hazards to aviation.
