I had a friend who was an airline pilot here in NZ and eventually 'retired' to Canada where his wife had come from. He was employed there by a company flying commuter planes, some times in some pretty dodgy conditions. Anyway I was chatting to him on one occasion about flying in the Northern Territory and he said they usually flew by LAR. Now I imagined that LAR was some sophisticated navigation system developed for such a difficult area, but no. LAR stands for....'.looks about right'.......this from an AirNZ pilot!!!!
