| …awaiting word from makersBy Gary EleazarA senior official at the Guyana Civil Aviation Authority (GCCA) yesterday said that the body is yet to identify the device recovered on Hope Beach, recently,Bobby Orr Jersey, by East Coast Demerara resident, Dennis Baksh.The GCAA has since sought the help of the company that made the piece of equipment, Sensorex.Baksh had found what is believed to be a part of the fuselage and a component believed to be the first piece of sensory equipment recovered from Air France Airbus A330-200 that crashed into the Atlantic Ocean after leaving neighbouring Brazil en route to France on June 1.The sensory component that was attached to the fuselage, according to Sensorex’s website, is described as a three-axis Inertial Measurement Unit (IMU) which is cylindrical in shape and is mounted on a flat base with electrical wiring protruding from within it. It bears the trademark ‘Sensorex.’Baksh had attempted to open the device but only managed to break into the cylindrical case; the cube within was impenetrable to Baksh.Another aviation official explained that the piece of equipment marked Sensorex might be the first piece of sensory equipment retrieved from the crashed plane.He explained that it sends signals to the flight panel and this might be the piece of malfunctioning equipment that caused the crash.An Inertial Measurement Unit (IMU) is the main component of inertial guidance systems used in air, space, and watercraft, including guided missiles. It is also called an inclinometer or a clinometer.An IMU works by sensing motion including the type, rate,Cheap Jerseys Online, and direction of that motion using a combination of accelerometers and gyroscopes.The data collected from these sensors allows a computer to track a craft’s position,Wholesale Authentic Jerseys Outlet, using a method known as dead reckoning.The IMU works by detecting the current rate of acceleration, as well as changes in rotational attributes, including pitch, roll and yaw.The data is then fed into a computer, which calculates the current speed and position, given a known initial speed and position.For example,Jerseys NFL Cheap, if an IMU installed in an airplane were to detect that the craft accelerated westward,Brett Hull Red Wings Jersey, resulting in a calculated constant speed of 500 miles per hour, and detected no other accelerations for one hour, then the guidance computer would deduce that the plane must be 500 miles west of its initial position.When combined with a computerised system of maps, the guidance system could use this method to show a pilot where the plane is located geographically, similar to a GPS navigation system but without the need to communicate with any outside components, such as satellites.The term IMU is widely used to refer to a box containing three accelerometers and three gyroscopes.The accelerometers are placed so that their measuring axes are orthogonal to each other. They measure inertial acceleration,http://www.airmaxfantasy.us.com/Adidas/, also known as G-forces.Three gyroscopes are placed in a similar orthogonal pattern, measuring rotational position in reference to an arbitrarily chosen co-ordinate system.IMUs are primarily used in vehicle-installed inertial guidance systems. Today almost every commercial or military water-going vessel has one.Most aircrafts are also equipped with IMUs.When Baksh found the piece of fuselage,Wholesale Jerseys, he said that there was also a thick foam-like material attached to the inside of the piece of fuselage, but this he removed, given that while it was water soaked it made the already heavy piece of debris almost immovable.The Police and the Guyana Civil Aviation Authority were subsequently contacted with the latter confirming that the piece of debris was definitely from a large aircraft and that the component bearing the trademark Sensorex was indeed a piece of sensory equipment used on aircrafts.The Brazilian Embassy and French officials have been contacted.At present, it is still unclear what caused the crash that killed 228 persons aboard.About seven hours after taking off and flying through the night over the mid-Atlantic,Discount NFL Jerseys, the pilots of the Air France Airbus reported that they had encountered an area of intense cumulonimbus activity,Cheap NFL Jerseys 2016, part of the massive thunderstorms that regularly batter the region.Air France reported that the aircraft’s ACARS (Aircraft Communications and Addressing System) a digital datalink that automatically transmits service messages from the aircraft to ground stations, messaged the company’s headquarters regarding a problem with the aircraft’s electrical and pressurisation systems.The French aircraft accident investigation agency, the Bureau d’Enquetes et d’Analyses (BEA) had announced that an examination of structural components of the aircraft recovered from the surface of the ocean, revealed that they were deformed from the bottom to the top.This according to BEA suggests that the aircraft hit the sea “in the direction of flight with a sharp vertical acceleration”. This in turn indicates that the aircraft was “not destroyed in flight”.The aeroplane’s speed sensors were “a factor but not the cause” of the disaster.The investigators had also determined that no distress call was made, either to air traffic control or to other aircrafts.The most direct evidence of the cause of the accident is the presence of suspected aircraft debris on the ocean surface and a series of 24 automatically generated maintenance messages that were transmitted from the plane shortly before the crash.Investigators also said that messages indicated that cabin pressure was lost and there was some kind of electrical system failure.Following the crash, a massive search was launched by the Brazilian Military as well as from France. |
