1999 Tramore Helicopter Crash
Shortly after midnight on 02 July 1999, a Eurocopter AS365 Dauphin, Eurocopter Dauphin search and rescue helicopter operated by the Irish Air Corps crashed into the sand dunes behind Tramore, Tramore beach in County Waterford while returning from a mission. All four crew aboard were killed. The helicopter was attempting to land at its base in nearby Waterford Airport, but was hampered by heavy fog. Background Thursday 01 July 1999 was the first day that a 24-hour helicopter search and rescue service was provided from Waterford Airport. The airport is located near the coast, just north of the large beach at Tramore. The Irish Air Corps was contracted to provide the service on behalf of the Irish Coast Guard, Irish Marine Emergency Service (IMES; now known as the Irish Coast Guard). The helicopter (callsign Rescue 111) was a Eurocopter AS365 Dauphin, Eurocopter AS365Fi Dauphin, which had flown in from the Air Corps base at Casement Aerodrome in County Dublin that morning wit ...

Waterford Airport
Waterford Airport () (IATA: WAT, ICAO: EIWF) is located in Killowen, southeast of Waterford. It serves southeastern Ireland. The airport is operated by Waterford Regional Airport plc. Its single scheduled route, operated by VLM Airlines—which used Waterford as its only Irish airport and kept a base there—was discontinued from 13 June 2016 as VLM went out of business, leaving the airport without any scheduled traffic. History Early years The airport's development was initiated by Waterford Corporation, with support from the Government of Ireland and the private sector, in 1979–1980. The investment was Irish pound, £1.76 million. Waterford Airport opened in 1981, with a runway for single and twin-engine light aircraft and a Portable building, portable cabin as the airport terminal, terminal building. The current terminal building was opened in 1992, and the runway was lengthened to . Avair provided the first domestic passenger service in 1982, as a stop between Cork ...

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, fully under pilot control, is unintentionally flown into the ground, a body of water or other obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending collision until impact, or it is too late to avert. 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 classified instead as uncontrolled flight into terrain, or UFIT. Incidents resulting from the deliberate action of the person at the controls, such as a forced landing, an act of terrorism, or suicide by pilot, are also excluded from the definition of CFIT. 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 aircra ...

Helvick
Helvick or Helvick Head (, ) is a headland on the southern end of Dungarvan Harbour, Ireland; it is the eastern tip of the Ring Peninsula. Formed of Old Red Sandstone, it is the easternmost protrusion of a ridge that begins near Cork City. Name Helvick is one of a very few Irish place names derived from Old Norse. The second part, -''vík'', means "bay" (cf. Smerwick); and ''-hel'' in Icelandic means death or danger. (See the Icelandic adjective ''helvískur'' which means dangerous). Helvik would be recognised by an Icelander as suggesting a dangerous harbour entrance, especially in view of the presence of the very dangerous ''Blackrock'' right in the entrance to Dungarvan Harbour and just over a mile from the headland of Helvick. The meaning of the first part is unclear, but it may mean "healthy", "white", "holy", or "safe"; compare with Hellvik, Norway. Wildlife Helvick Head is a Special Area of Conservation (SAC). The cliffs are a nesting site for seabirds includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Dumping
Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight. Aircraft fuel dump Weight issues Aircraft have two main types of weight limits: the maximum takeoff weight is composed of DOW (Dry Operating Weight) plus Payload (passengers and cargo), collectively the ZFW (Zero Fuel Weight), plus the trip fuel, contingency, alternate, final reserve and the block fuel (taxi fuel), and the maximum structural landing weight, with the maximum structural landing weight almost always being the lower of the two. This allows an aircraft on a normal, routine flight to take off at a higher weight, consume fuel en route, and arrive at a lower weight. It is an abnormal, non-routine flight where landing weight can be a problem. If a flight takes off at the maximum takeoff weight and then must land w ...

Lowest Safe Altitude
In aviation (particularly in air navigation), lowest safe altitude (LSALT) is an altitude that is at least 500 feet above any obstacle or terrain within a defined safety buffer region around a particular route that a pilot might fly. The safety buffer allows for errors in the air by including an additional area that a pilot might stray into by flying off track. By flying at or above this altitude a pilot complies with terrain clearance requirements on that particular flight leg. Australian definition * The minimum LSALT is 1500 feet. * LSALT is 1360 feet above the highest terrain where any obstacle thereon is less than 360 feet above the terrain, or there is no charted obstacle. * LSALT is 1000 feet above the highest obstacle which is greater than 360 feet above the terrain. For example, if there is an obstacle at 200 feet above terrain of 2500 feet, LSALT is 2500 feet (terrain height) + 1360 feet (clearance height), for an LSALT of 3860 feet; if there is an obstacle at 450 fee ...

Minimum Descent Altitude
In aviation, an instrument approach or instrument approach procedure (IAP) is a series of predetermined maneuvers for the orderly transfer of an aircraft operating under instrument flight rules from the beginning of the initial approach to a landing, or to a point from which a landing may be made visually. These approaches are approved in the European Union by EASA and the respective country authorities, and in the United States by the FAA or the United States Department of Defense for the military. The ICAO defines an instrument approach as "a series of predetermined maneuvers by reference to flight instruments with specific protection from obstacles from the initial approach fix, or where applicable, from the beginning of a defined arrival route to a point from which a landing can be completed and thereafter, if landing is not completed, to a position at which holding or ''en route'' obstacle clearance criteria apply." There are three categories of instrument approach proced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Altimeter
A radar altimeter (RA), also called a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft. This type of altimeter provides the distance between the antenna and the ground directly below it, in contrast to a barometric altimeter which provides the distance above a defined vertical datum, usually mean sea level. Principle As the name implies, radar (radio detection and ranging) is the underpinning principle of the system. The system transmits radio waves down to the ground and measures the time it takes them to be reflected back up to the aircraft. The altitude above the ground is calculated from the radio waves' travel time and the speed of light. Radar altimeters required a simple system for measuring the time-of-flight that could be displayed u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockpit Voice 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 colloquially as a "black box", an outdated name which has become a misnomer—they are now required to be painted Safety orange, 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 Internation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helicopter Flight Controls
Helicopter flight controls are used to achieve and maintain controlled aerodynamic helicopter flight. Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a desired way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades ''cyclically'' during rotation, creating differing amounts of lift at different points in the cycle. To increase or decrease overall lift requires that the controls alter the angle of attack for all blades ''collectively'' by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration. A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a ''mixing unit'', a mechanical or hydra ...

Missed Approach
Missed approach is a procedure followed by a pilot when an instrument approach cannot be completed to a full-stop landing. Initiation A missed approach may be either initiated by the pilot or instructed by air traffic control (ATC). The instructions for the missed approach may be assigned by ATC prior to the clearance for the approach. If ATC has not issued specific instructions prior to the approach and a missed approach is executed, the pilot must follow the (default) missed approach procedure specified for the approach. Prior to commencing the approach, pilots can make a specific request to ATC if a missed approach may occur. Such a request may include heading and altitude instructions to avoid in-flight delays (such as holds) and efficiently maneuver the aircraft into position for either its next approach or a diversion to an alternate airport. Generally, if a pilot determines by the time the aircraft is at the Instrument approach#Decision height or altitude (Precision Appr ...
