2017 Irish Coast Guard S-92 Crash
In the early hours of 14 March 2017, a Sikorsky S-92 helicopter operated by CHC Helicopter under contract to the Irish Coast Guard (call sign Rescue 116) crashed into the sea while supporting a rescue operation off County Mayo, on Ireland's west coast. All four crew members on board, Captain Dara Fitzpatrick, Chief Pilot Mark Duffy, winch operator Paul Ormsby, and winch man Ciarán Smith were killed. In a preliminary report published in April 2017, the Air Accident Investigation Unit found that the helicopter had clipped the small island of Blackrock at an altitude of around while on approach to Blacksod Lighthouse for a refuelling stop, and subsequently crashed out of control into the sea. Events On 14 March 2017, Rescue 118 had completed the medical evacuation of an injured fisherman west of Blacksod, for which Rescue 116 had provided support, and was returning. Shannon ATC last had communication from Rescue 116 at shortly before the crash announcing 'making our way to Bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controlled Flight Into Terrain
In aviation, a controlled flight into terrain (CFIT; usually ) is an aviation accidents and incidents, accident in which an airworthy aircraft, under aircraft pilot, pilot control, is unintentionally flown into the ground, a mountain, a body of water or an obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending disaster until it is too late. The term was coined by engineers at Boeing in the late 1970s. Accidents where the aircraft is out of control at the time of impact, because of mechanical failure or pilot error, are not considered CFIT (they are known as ''uncontrolled flight into terrain'' or ''UFIT''), nor are incidents resulting from the deliberate action of the person at the controls, such as acts of terrorism or suicide by pilot. According to Boeing in 1997, CFIT was a leading cause of airplane accidents involving the loss of life, causing over 9,000 deaths since the beginning of the commercial jet aircraft. CFIT was identified as a cause of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish Naval Service
The Naval Service ( ga, An tSeirbhís Chabhlaigh) is the maritime component of the Defence Forces of Ireland and is one of the three branches of the Irish Defence Forces. Its base is in Haulbowline, County Cork. Though preceded by earlier maritime defence organisations, the Naval Service was formed in 1946. Since the 1970s a major role of the Naval Service has been the provision of fisheries protection in Ireland's exclusive economic zone (EEZ). Other roles include sea patrol, surveillance, and smuggling prevention. Occasionally the service undertakes longer missions in support of other elements of the Defence Forces, Irish peacekeepers serving with the United Nations, or humanitarian and trade missions. From July 2017 the Naval Service has participated in the European External Action Service mission which focuses a number of EU navies on humanitarian and training roles in the Mediterranean. This mission entitled "EU Navfor Med" is the first time Ireland has taken part in a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra-short Baseline
USBL (ultra-short baseline, also known as SSBL for super short base line) is a method of underwater acoustic positioning. A USBL system consists of a transceiver, which is mounted on a pole under a ship, and a transponder or responder on the seafloor, on a towfish, or on an ROV. A computer, or "topside unit", is used to calculate a position from the ranges and bearings measured by the transceiver. Mechanism An acoustic pulse is transmitted by the transceiver and detected by the subsea transponder, which replies with its own acoustic pulse. This return pulse is detected by the shipboard transceiver. The time from the transmission of the initial acoustic pulse until the reply is detected is measured by the USBL system and is converted into a range. To calculate a subsea position, the USBL calculates both a range and an angle from the transceiver to the subsea beacon. Angles are measured by the transceiver, which contains an array of transducers. The transceiver head normally co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Recorder
A flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. The device may often be referred to as a "black box", an outdated name which has become a misnomer—they are now required to be painted bright orange, to aid in their recovery after accidents. There are two types of flight recording devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation. The two flight recorders are required by international regulation, overseen by the International Civil Aviation Organizat ...

Aircraft Emergency Frequency
The aircraft emergency frequency (also known as GUARD) is a frequency used on the aircraft band reserved for emergency communications for aircraft in distress. The frequencies are 121.5 MHz for civilian, also known as International Air Distress (IAD) or VHF Guard, and 243.0 MHz—the second harmonic of VHF guard—for military use, also known as Military Air Distress (MAD) or UHF Guard. Earlier emergency locator transmitters (ELTs) used the guard frequencies to transmit, but an additional frequency of 406 MHz is used by a more modern emergency locator transmitter. History The choice of 121.5 MHz was made by ICAO in conjunction with ARINC and the ITU. Monitoring In the United States, the emergency frequency is monitored by most air traffic control towers, FSS services, national air traffic control centers, military air defense and other flight and emergency services, as well as by many commercial aircraft. The notice to airmen FDC 4/4386 requires "…all aircr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LÉ Samuel Beckett (P61)
LÉ ''Samuel Beckett'' (P61) is a (OPV) of the Irish Naval Service. The ship was launched in November 2013 and commissioned in May 2014. She is named after Irish playwright and author Samuel Beckett. Like other OPVs in the Irish Naval Service, the ship's primary mission is fisheries protection, search and rescue, and maritime protection operations, including vessel boardings. Development Design In October 2010, the Irish Naval Service ordered a number of new offshore patrol vessels from Babcock Marine, a UK-based shipbuilder operating out of Appledore, North Devon. The first two vessels were named ''Samuel Beckett'' and respectively, and planned to replace (decommissioned September 2013; sold October 2013) and (decommissioned January 2015; commissioned in the Maritime Squadron of the Armed Forces of Malta June 2015). Like the ''Róisín''-class OPV, ''Samuel Beckett'' was designed by Vard Marine to a VARD 7 series design. Although similar to the ''Róisín''-class O ...

Commissioners Of Irish Lights
The Commissioners of Irish Lights ( ga, Coimisinéirí Soilse na hÉireann), often shortened to Irish Lights or CIL, is the body that serves as the general lighthouse authority for Northern Ireland and the Republic of Ireland and their adjacent seas and islands. As the lighthouse authority for the island of Ireland it oversees the coastal lights and navigation marks provided by the local lighthouse authorities, the county councils and port authorities. It is funded by light dues paid by ships calling at ports in the Republic of Ireland, pooled with dues raised similarly in the United Kingdom. This recognizes that a large volume of shipping, typically transatlantic, relies on the lights provided by Irish Lights. History Signal fires to guide shipping have long existed. Hook Head has the oldest nearly continuous light in Ireland, originally a signal fire or beacon tended by the monk Dubhán in the fifth century. Monks continued to maintain the light until the Cromwellian co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multibeam Echosounder
A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth. Unlike other sonars and echo sounders, MBES uses beamforming to extract directional information from the returning soundwaves, producing a swath of depth soundings from a single ping. History and progression Multibeam sonar sounding systems, also known as ''swathe'' (British English) or ''swath'' (American English), originated for military applications. The Sonar Array Sounding System (SASS) was developed in the early 1960s by the US Navy, in conjunction with General Instrument to map large swaths of the ocean floor to assist the underwater navigation of its submarine force. SASS was tested aboard the USS ''Compass Island'' (AG-153). The final array system, composed of sixty-one one degree beams with a swa ...

LÉ Eithne (P31)
LÉ ''Eithne'' (P31) was a patrol vessel in service with the Irish Naval Service. The ship is named after Eithne, a tragic heroine and the daughter of the one-eyed Fomorian King, Balor in an early Irish romantic tale. ''Eithne'' was the flagship of the Irish Naval Service. ''Eithne'' was originally built as a Helicopter Patrol Vessel for long-range fisheries patrol vessel, intended to be at sea for up to 30 days. She is the only ship in her class, as the other planned members of the ''Eithne''-class were never built. Design ''Eithne'' was designed to carry a SA365F Dauphin helicopter, and was the only ship in the Irish Naval Service fleet to have a flight deck. Helicopter operations were limited primarily to the vessel's early years of service. These operations stopped in later years, due in part to the purchase of CASA CN235-100MP Persuader Maritime Patrol Aircraft and decommissioning of the Dauphin helicopters. The vessel was fitted with retractable fin stabilisers to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal National Lifeboat Institution
The Royal National Lifeboat Institution (RNLI) is the largest charity that saves lives at sea around the coasts of the United Kingdom, the Republic of Ireland, the Channel Islands, and the Isle of Man, as well as on some inland waterways. It is one of Independent lifeboats in Britain and Ireland, several lifeboat services operating in the same area. Founded in 1824 as the National Institution for the Preservation of Life from Shipwreck, soon afterwards becoming the Royal National Institution for the Preservation of Life from Shipwreck, under the patronage of King George IV. On 5 October 1854, the institution’s name was changed to its current name (RNLI), and in 1860 was granted a royal charter. The RNLI is a charity in the UK and in the Republic of Ireland and has enjoyed royal patronage since its foundation, the most recent being Elizabeth II of the United Kingdom, Queen Elizabeth II until her death on 8 September 2022.
