Fait Accompli - French Phrases in International Air-sea Rescue

French Phrases in International Air-sea Rescue

International authorities have adopted a number of words and phrases from French for use by speakers of all languages in voice communications during air-sea rescues. Note that the "phonetic" versions are presented as shown and not the IPA.

SECURITAY
(securité, "safety") the following is a safety message or warning, the lowest level of danger.
PAN PAN
(panne, "breakdown") the following is a message concerning a danger to a person or ship, the next level of danger.
MAYDAY
( m'aider, come to help me"; note that aidez-moi means "help me") the following is a message of extreme urgency, the highest level of danger. (MAYDAY is used on voice channels for the same uses as SOS on Morse channels.)
SEELONCE
(silence, "silence") keep this channel clear for air-sea rescue communications.
SEELONCE FEE NEE
(silence fini, "silence is over") this channel is now available again.
PRU DONCE
(prudence, "prudence") silence partially lifted, channel may be used again for urgent non-distress communication.
MAY DEE CAL
(médical, "medical") medical assistance needed.

It is a serious breach in most countries, and in international zones, to use any of these phrases without justification.

See Mayday (distress signal) for a more detailed explanation.

Famous quotes containing the words french, phrases and/or rescue:

    “This has been illustrated copiously each day with photographs taken by the author, reproduced by means of cuts such as only French newspaper-engravers can make, presumably etched on pieces of bread.”
    —Robert Benchley (1889–1945)

    “It is a necessary condition of one’s ascribing states of consciousness, experiences, to oneself, in the way one does, that one should also ascribe them, or be prepared to ascribe them, to others who are not oneself.... The ascribing phrases are used in just the same sense when the subject is another as when the subject is oneself.”
    —Sir Peter Frederick Strawson (b. 1919)

    “I positively like the sense, when I dine out, and stoop to rescue a falling handkerchief, that I am not going to rub my shoulder against a heart. What are hearts doing on sleeves?”
    —Katharine Fullerton Gerould (1879–1944)
