I just found this exact same question in the Bob Tait Cyberexam IREX-1. There is no mention of a GPS in this question, so I still believe this must have been a question from an Instructor trying to trick his student...
Would love to know where he was asked this question. Bob Tait uses VH-OZY in most of his questions, and in the real world VH-OZY is C172 in rockhampton.
Does ASA use VH-OZY too??
