Mayday Parade Albums
Mayday is an emergency procedure word used internationally as a distress signal in voice-procedure radio communications. It is used to signal a life-threatening emergency primarily by aviators and mariners, but in some countries local organizations such as firefighters, police forces, and transportation organizations also use the term. Convention requires the word be repeated three times in a row during the initial emergency declaration ("Mayday mayday mayday") to prevent it being mistaken for some similar-sounding phrase under noisy conditions, and to distinguish an ''actual'' mayday call from a message ''about'' a mayday call. History The "mayday" procedure word was conceived as a distress call in the early 1920s by Frederick Stanley Mockford, officer-in-charge of radio at Croydon Airport, England. He had been asked to think of a word that would indicate distress and would easily be understood by all pilots and ground staff in an emergency. Since much of the air traffic a ...

Procedure Word
Procedure words (abbreviated to prowords) are words or phrases limited to radio telephone procedure used to facilitate communication by conveying information in a condensed standard verbal format. Prowords are voice versions of the much older procedural signs for Morse code which were first developed in the 1860s for Morse telegraphy, and their meaning is identical. The NATO communications manual ACP-125 contains the most formal and perhaps earliest modern (post-World War II) glossary of prowords, but its definitions have been adopted by many other organizations, including the United Nations Development Programme, the U.S. Coast Guard, US Civil Air Patrol, US Military Auxiliary Radio System, and others. Prowords are one of several structured parts of radio voice procedures, including brevity codes and plain language radio checks. Examples According to the U.S. Marine Corps training document FMSO 108, "understanding the following PROWORDS and their respective definitions is ...

Call For Help
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance. A distress signal indicates that a person or group of people, ship, aircraft, or other vehicle is threatened by a serious or imminent danger and requires immediate assistance.Aeronautical Information Manual U.S. Federal Aviation Administration, 2016 Use of distress signals in other circumstances may be against local or .

Vessel Emergency Codes
In addition to distress signals like Mayday and pan-pan, most vessels, especially passenger ships, use some emergency signals to alert the crew on board. In some cases, the signals may alert the passengers to danger, but, in others, the objective is to conceal the emergency from unaffected passengers so as to avoid panic or undue alarm. Signals can be in the form of blasts on alarm bells, sounds on the ship's whistle or code names paged over the PA system. *Alpha, Alpha, Alpha is the code for a medical emergency aboard Royal Caribbean ships. *Alpha Team, Alpha Team, Alpha Team is the code for a fire emergency aboard Carnival Cruise Line ships. *Assemble at Muster Stations (General Emergency Signal), seven short blasts followed by one long blast of the ships horn and internal alarm bell system. *Bravo, Bravo, Bravo is used by many cruise lines to alert crew to a fire or other serious incident on board without alarming passengers. *Operation Brightstar designates a medical emergency ...

Sécurité
Sécurité (; French: ''sécurité'') (often repeated thrice, "Sécurité, sécurité, sécurité") is a procedure word used in the maritime radio service that warns the crew that the following message is important safety information. The most common use of this is by coast radio stations before the broadcast of navigational warnings and meteorological information. Navigational warnings are issued regularly and usually give information about people or vessels in distress and objects or events that can be an immediate danger to people at sea and how they are navigating. In the United States, MARAD (Marine Administration) sends out infrequent advisories about potential global political climate dangers. There are four types of navigational warnings, which are categorized by their location. These areas are NAVAREA IV, HYDROLANT, NAVAREA XII, and HYDROPAC. Meteorological information is information that is about the marine atmosphere. These meteorological advisories include the develop ...

Global Maritime Distress Safety System
The Global Maritime Distress and Safety System (GMDSS) is a worldwide system for automated emergency signal communication for ships at sea developed by the United Nations' International Maritime Organization (IMO) as part of the SOLAS Convention. It's a set of safety procedures, types of equipment, and communication protocols used for safety and rescue operations of the distressed ships, boats, and aircraft. It's supplemental to the International Convention on Maritime Search and Rescue (ICMSaR) adopted in 1979 and provides basis for the communication. GMDSS consists of several systems which are intended to perform the following functions: alerting (including position determination of the ship in distress) ships in the vicinity and ashore authorities, search and rescue coordination, locating (homing), maritime safety information broadcasts, general communications, and bridge-to-bridge communications. Specific radio carriage requirements depend upon the ship's area of operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
