Summary
Aircraft was being vectored for a visual approach at Cairns, with an assigned radar lowest safe altitude of 3600ft. Approximately 18km north-west of Cairns, while heading east towards the coast, the ground proximity warning alarm activated. An immediate climb to 4000ft was initiated. The aircraft did not descend again until after crossing the coast to become visual and then made a visual approach and landing. No breakdown of separation occurred.
Later engineering examination confirmed that the alarm activation was a false indication, which was caused by an electrical fault in the GNS Omega navigation system.
