00:00Once a major accident occurs in the aviation or maritime field,
00:02the captain or the captain will send out a distress signal from Mayday.
00:05Besides this, what's the difference between Panpan and Mayday?
00:08It's okay if you don't understand. It's useless even if you understand.
00:09Why do you need to understand?
00:11Mayday is a distress signal that is often heard and often seen.
00:13Of course, it has nothing to do with Mayday,
00:15but it comes from French, which means fast aid.
00:17A senior wireless communicator who boarded the British Royal Aircraft Carrier
00:21proposed in 1923 that
00:22since most of the passengers returned to Paris, France at that time,
00:25the French vocabulary was chosen
00:27and later applied to the aviation field.
00:29Another distress signal, Panpan,
00:31is no more urgent than Mayday.
00:32For example, if a ship or a plane has a malfunction and is out of control,
00:35attacked by pirates,
00:36or someone needs immediate medical assistance,
00:39you need to call Panpan three times.
00:41If two planes are in danger at the same time,
00:43one sends out Mayday and the other sends out Panpan,
00:45then the plane that calls Mayday has priority assistance.
00:48However, only in very urgent situations
00:50can you send out a Mayday signal.
00:52Using a distress signal may require criminal liability.
