Aircraft making late turns after departure from Runway 15 impacts on residents in the Esplanade area in Cairns. The investigation established that this was occurring more frequently than expected. Airservices wrote to the airlines to communicate the community concerns and ask for confirmation that they would comply with the requirements of the departure procedure at all times, unless there were critical reasons not to do so (ie emergency or weather). Subsequently community representatives on the Airport Environment Consultative Committee noted that they had seen a difference.
