You have abandoned ship and after two days in a life raft you can see an aircraft near the horizon apparently carrying out a search pattern. You should __________.

Correct Answer: Option D — use visual distress signals in conjunction with the EPIRB

While an EPIRB provides a location signal, visual distress signals like flares or smoke are essential for final identification by search aircraft. Using these in conjunction with the EPIRB maximizes the probability of detection, as the aircraft can correlate the electronic signal with a visible target on the surface.
