SHELLHARBOUR City Council warned residents not to panic if they heard emergency sirens at the Illawarra Regional Airport last Thursday.
Emergency service agencies ran an exercise to test procedures and methods during a surprise mock incident last week.
The event was a mock simulation of a light plane requesting an emergency landing on the runway.
The exercise involved a pilot and passenger who required treatment by ambulance crews.
The objectives were for the Combat agencies and the council to exercise communication procedures, site access and site control for a multi-agency response at the airport.
The Civil Aviation Safety Authority requires the multi-agency exercise be conducted once a year.
Mayor Marianne Saliba said as the caretaker of the airport, council worked closely with emergency agencies to facilitate a prompt and capable response to any possible incident on the site.
