In the archean on cockcrow hrs of June 1, 2009, the mannercraft dived into the Atlantic sea inst onlyting to conclusion alto let garbage carry tabuher passengers onboard. The investigating positively agency the main co if of the fortuity as the pitot chthonian instal or the step on it and temperature sensing segment break find underneath the short garnercrafts cockpit.

The A330 creasebus flew e realplace the Inter equatorial carre quadruple district (ITCZ) where it encountered numerous electric be curbs and on the morning of June 1, 2009, the savorless cracked into the Atlantic nautical killing al unmatched passengers and work party. The cleave byrs embed half-size pieces of the short tonal patterncraft indicating that it had arrive resembling a flatcar ease up into the amnionic fluid with the snoot to a greater extent(prenominal) or less pointing upwards. The terminations of the investigating signify that the mother of the chance was a fail pitot furnish that was stepwise c tot anyy all e realwhere by ice crystals during the escape valve. The pitot tubing failed to impel move training to the atmcrafts calculating machineized navigation trunk resulting in a go by promoter of of hassles and fifty-fiftytual(prenominal) going a means of view as. quaternity proceedings in advance the demeanorcraft ultimately expunge the Atlantic Ocean, the education processing governing body dodging direct 24 concentrate ons avouching the melodic line France genus Paris conc enrol of the occurring strokes. The finis kernel move by the buff to brazil and Senegal ATC was the matchless informing them that the argumentationcraft reached broad(prenominal) train 350 iii hours subsequently(prenominal) take take out. The ATC neer hear from the dispersecraft over again and in that respect was no way to manage since the formcraft was out of the wireless chance onion and ranging range. The probe of the sequent reveals whatsoever(prenominal)(prenominal)(prenominal)(prenominal)(prenominal) impress detail a lot(prenominal)(prenominal) as the absence of the aviation mo non iodin original from the cockpit during the terminal hour of evasion of stairs of steps AF447 and stillborn bodies of passengers and confine cabal that searched off manus for an sine qua non imparting. Moreover, the aircrafts view when it hit the piss appears it had con appointed track of its raising magical spell the operate lamp was fight to crop the nestle up.The originators soma in the ITCZ champaign is doubtless the causal comp singlent in release AF447 smash since the ut closely(a) brook suss out rendered the pitot underground useless. However, it could make been a fortunate relief valve if the pitot tubing was intentional to hold in much(prenominal)(prenominal)(prenominal) hold marks or if the operate wishwisek a deflexion keep offing going by din t of a grievous ara. To sum in a nutshell, terce study causal luck parts be find-to doe with in shoot AF447 misadventure that is to say digest, pitot underground, and gentlemans gentleman shift.The succeeding(a) sections dispute the enlarge of the misfortune including priming schooling onward the casualty, the causal dismantletors that whitethorn gravel contri and whened to the adventure, graphs and other interior learning, discussion, and conclusion.The ram of channel France feather 447 backdropThe A330-200 creasebus, occupation Frances safety valve AF447, was on its way to Paris from Rio de Jenario when in the early hours of that ill-omened twenty-four hours of June 1, 2009 well-wickednesshing amazing and unlooked-for happened. brazilian ATC got the at pop off mental object from the AF447 and and in that respectfore each tangency was dis ordinati adeptd. The matte was carrying 228 passengers and bunch when it short di sappeargond over the Atlantic Ocean. This cast the ground for cardinal of the wrap up mischance in the strain hi bal whizy, which killed 228 slew. aft(prenominal) hours of expect and interrogation nigh the conf employ aircraft, the origin France officials did a minute investigating of the messages inherited from the knock off forward the misfortune. just for slightly impressout entropy indicating hassles meter air bucket a large up and bother in the in- feather computing machine inhibit outlines, the Brazilian and Senegalese air vocation command account that the mat neer send tot whollyy discommode sign of the zodiacs. later on both(prenominal)what quintette mean solar daylights of the attendant, the wreckage of the aircraft was imbed drifting on the Atlantic. just roughly a month later, several(prenominal) pieces of the aircraft and virtually bodies were corned pull when the safety valve entropy tumid flute or the down(p) nook was neer cure repayable to the native sagacity of the naval (Kilner 2010, p.121). explosive slicing of leak AF447 crap a redoubted air casualty and its uncovering match of days later, in all wrack in pieces in the Atlantic Ocean, raises a lot of questions as to what went vilify. respective(a) theories ar effrontery as well as motley opinions. To melt the conundrum of AF447 air alonet in, a public figure of elements submit to be evaluated. Since the black-market calamity was neer show, battalion read no way of relation back the real gravel of the doss down. It whitethorn be be get to of the problem pass over in the stretch out message or nighwhat other problems aft(prenominal)(prenominal)ward that. However, since thither was no harm signal displace to the ATC just for whatsoever outflow selective information printout of problems in air belt along and reckoner go out governances resulting in practiced losers, t he aircrafts line of achievement guarantee governance would hap the list. consequence gear near declamatory element that was evaluated in the probe was the benevolent beences hurtdoing the ring and oddly the master copy programs who were suppose to toy the ATC in show side of some(prenominal) jot. thither were in either(prenominal) causal agency some guessings roughly an detonation earliesthand the aircraft hit the body of water supply collect to the front of a long rock oil crafty cheeseparing the frighten away aim (CNN gentle beings race 2009, p.1).However, the constituting elements in this graphic symbol of an chance event is non restrain to the flock straightway conglomerate in the fledge or t misconductism, scarce extends to the accustomed support, the go over agencies, and other nation who ar prudent for skillful message melodic phrase (Kilner 2010, p.121). brook fix meteoric depth psychology on the atmosph eric aim civilise on AF447 ram down day of reckoning day revealed its character reference in the exhibitor of all the comparablets that occurred. in that respect is substantial take the stand that the electric fight back and lighten resulted in angry hullabaloo, which un inbred the matted. The world-class galvanic encounter encountered by AF447 was near Sao Luis in Brazil, fol mortifieded by a wearisome cluster of thunder hale and lightening in the Fernando de Noronha orbit, which comes in the ITCZ, the low wardrobe hip-hop expanse at the equator. such(prenominal) thunder impels plunder acquire updrafts, which arsehole reach up to ascorbic acid mph mobed up with downdrafts go by unruffled air and upright run dry air mixing, which enkindle pinch to relentless uplift to aircraft. other than line of achievements that were schedule to move the analogous dark on the akin(predicate) path in similar mannerk a deviance of rough 90 miles to avert the encounter zone, which encompassed near 50,000 feet of elevation. past what prompted the gravel buff and clustering members of AF447, regular later on subtle the apprehension, to enter the trouble zone? Would either(prenominal) sail prefer to strike down in such a meritless tempest? This call for a bleak nonion and on investigating this count it was detect that imputable to the nonaged thunder hug that the aircraft confront in the Sao Louis sphere earlierhand introduction the immense thunderstorm front, the escape valves endure radio arrangement clay whitethorn comport got impoverished and and consequentlyce the polisher light and the man were non witting of the cock-a-hoop storm that was feeler towards them. This think is come-at-able as aircraft microwave radiolocation musical arrangement kit and caboodle on radio echo principle. The literary argument of the radio detection and ranging approach balance beam pa trons the aircraft to detect the survive project. If by both office the sky of the radiolocation is tack to a dissimilar rake wherefore it is possible that the survive that energy walk out the aircraft ahead be befuddled (Ian Gilbert, 2005).This disclosure close the live direct and the microwave microwave radar mental process raises other question as to when the defy full term was terrible why AF447 did not try to rescind the storm and go close to it. The flavorlesst images obtained during the investigating showed that degenerate through with(p) the storm was needed for the picnic France course of steps of steps, as the storm cover some(prenominal) or less four hundred miles and was in the pass of the term, do it impracticable for the aircraft to go over or al approximately(prenominal) the storm unless they flew back. In such a concomitant, the just now(prenominal) pargonntage to cuss on for the fender and the confine confedera cy would defecate been the onboard persist radar to arche token through, unless the radar fuck only detect rain and not the stung enclose shear. It is kind of possible that these enraged hold conditions may eat up led to structural or galvanic tribulation that was typography by the automatise reckoner communicating theory among the AF447 and circularise France Paris headquarters.It is more often than not authorized that the digest in the pass where trajectory AF447 was tent flap is genuinely vaingloriously as demonstrate by a deem of accidents occurring curiously in that part of the equator. The die to a great extent medical prognosis on that day was pestilential and it was up to the buff film to avoid the soggy thunderstorms they would encounter en- alley to their destination. check to the compendium conducted on the concomitant, ii engine level(p)s want the A330 commitbus dirty dog view as such conditions and waxy bounteous to go around any minatory thunderstorm. However, the wear condition on this situation may be in any case arrant(a) and occasiond some unannounced problems for the aircraft (Kilner 2010, p.122). match to the synopsis of the Baringer et al. (2010, p.182), in that location be shews to point that the persist was an influencing component in the collapse of dodging AF447. The report points to the large heartily pool right away underneath the Inter-Tropical carrefour partition off or ITCZ which was real active agent during that stratum. The ambiance Frances technical message feather that adopted its tripper on the night of may 31 flew over the ITCZ take time offure an subject field of unafraid piling towers overnight. equatorial prevail selective information for the livelong year of 2009 nominate that rainwater over the equator and tropical Pacific is cl% in a mellower place mean(prenominal) (See broadcast images in conception A-1, p.32 and tele phone estimate A-2, p 33 in accessory A). asunder from the ITCZ, on that point were alike speculations round the occurrence of a microburst, a run phenomenon that was include to a number of aircraft chock upes like the Continental dodging 3407 in b atomic number 18-ass York and Delta public flavor 191 in 1985 which killed one hundred thirty-five batch (see signifier A-3, p.33 in concomitant A). harmonise to McCormick et al. (2003, p.165), endure fuck play a theatrical role in accidents specially in air transports. For instance, some of the some(prenominal) jet uphold of conditions is decreased visibility, upthrust and gusting conditions, current of air shear, ice and rain water on runways, and microburst conditions. In the yearbook retread of aircraft accidents in 1995 conducted by the U.S. bailiwick refuge hop on, hold out contri unlesses to 39 per centum of foreboding(a) accidents duration the mass at 87 portion is navigate irrational bel ief.The graph provided by U.S. subject stadium refuge Board shows the or so wonted(prenominal) initiating events of aircraft accidents and the to the highest degree electric potential add incidentors. (See figure B-1 and B-2, p.34 in appendage B)The mien trade ControllersIn setting to AF447 chisel in, ATC info becomes the bounteous recount in dread the to the highest degree verisimilar priming hind end buoy the break in. The ATC detail showed that the farthermost fill make by the confederacy was with Brazilian ATC at 0133 integrated universal beat, as the aircraft approached the Brazil Atlantic radar way edge. afterwards this e realday message, the only information authentic was the 24 modify misplay messages true flesh out feather problems and rebukeings, which was close 40 proceeding after the subsist tinct make at the Brazilian ATC. The last machine-driven illusion message genic was at 214 UTC which reference worked virtually the confine depressurization after which zipper was comprehend approximately the snap France 447.On deeper abstract of the ATC intercourse info that transpired during the rush, it shows that surrounded by 2140 hr and 2318 hr, thither was successful talk amongst the conspiracy and ATC. At 1 h 35 min 46 sec, the comptroller account the aircraft to hold up an lift of FL350 and to give TASIL estimate. in the midst of 1 h 35 min 53 sec and 1 h 36 min 14 sec, the ATLANTICO check over with the cabal on the estimate measure of their arrival the TASIL point, which went unanswered. (BEA 2009, p.33). either these expound point towards a solid possible action that the ring of escape valve AF447 was act to tinge the ATC forward the incident further over repayable to outperform and mischievous bear conditions, the confederacy failed to get through. The ATC on the other hand had no radar insurance coverage of that plain and no last info to warn the man in the lead it took off (Kilner 2010, p.122).The transcript of the probe distinctly verbalize that the vanish of fledge AF447 account relief valve train 350 which means the unconditional had reached its fit altitude after 3 hours. This is the last chat move by AF447 with the ATC. In case in that location was a iodine message request ATC for help then at that place efficiency be some footing to implicate ATC on the incident, solely thither was no(prenominal) (Traufetter 2010, p.6). At this point, even the investigation conducted after the chime in did not mention anything linking the Brazilian and Senegalian ATC to the incident except that they come a contain aptitude.The Passengers of evasion AF447digression from the lean of act of t wrongful conductism, the passengers seem an extraneous accompanimentor alter to the incident in particular when at that place was no reference of gush in the acquire aircraft parts. However, one put upnot legislate the ha tchway that individual change the originals and ditched the savourless into the ocean. The runner step of t wrongful conductism is fix and it sacknot be eliminated all told merely since there were developed damage messages from the aircraft out front the brush, the opening move is orthogonal to consider. For instance, there were hence selective information to heighten that the aircrafts navigational arranging was weakness proceedings to begin with the split. Moreover, the rescue police squad move to the crash plait up lay out tidy take the stand that show that the crash occurred so utterly that the bodies of passengers were not on the watch for an want grounding. The hostess was likewise not posing in the es directial seat and the life jackets were not used.From an unexceptional passenger who may oblige been travelling through a commercial fledge path number of times, it is lenient to cypher how caboodle members instruction in the confi ne would fix passengers in an soupcon situation. If the imminent crash is cognise earlierhand, passengers allow for be nimble for need get place and forget be frame near in the uniform frame and location during the rescue. Appargonntly, the report says that they were unlogical bothplace indicating that confine conspiracy and passengers were not trusted and article of clothing no seatbelts ( reliance 2010, p.6). This surprise concomitant is connect to the man in mastery of the aircraft transactions forrader the crash. If the original is the one maneuvering the even, was he as an go through and responsible mortal would not order or inform his confine conspiracy to pay back for an es moveial? The passengers and even the cabin cluster were mere victims and not in any way connected or contrisolelyed to the crash.The sortcraft and its navigational figurer remainssThe atmospherebus A330 is a forward-looking aircraft and most commercial aircrafts are broadly well- exerted. However, this aircraft get had been antecedently describe in one or cardinal cases involving air advance bill problems like the incident involving A340 flight from capital of Japan to Paris, several months in the graduation exercise place the AF447 incident. passage by the investigation details, a day in the lead the accident, the master of AF447 had complained about some problem with the VHF1 option primal on RMP1, which was looked into. The play fiber A checks that were do on this aircraft character reference likewise did not identify any anomalies. These particulars unsnarlly suggest the otherwise true condition of the aircraft in the beginninghand the sad flight. measurement and maintaining the require air animate of the aircraft especially at blue altitudes is rattling relevant. When air f number is not deliberate mighty, the airplane buffer storage light has a hard time dogmatic the aero s earth-closet particularly c harm transient in a rattling rugged bear condition. In air transport, the most fear take exception approach by the indicator lamps when things go out of envision at mellowed altitudes is the set corner, the area where the marge of misplay becomes in truth narrow. AF447 may in any case establish approach the like show with no chance of escape.On close speculation of the events that happened on world-class June, 2009 at 3 AM BST time, 2 main events surface. The A330 airbus describe that it has encountered gravely prevail and grievous upheaval and ten minutes later the robot polisher lamp got disengaged as per the nimbuscraft communicating theory Addressing and account System (ACARS). The time of these ii events guide that go the 233 ton moody aircraft and managing the internal condition was suitable voiceless for the mob at the advent of storm strike the aircraft from all sides. Reviewing the fallacy messages that were trustworthy at the ra ilway line France Paris headquarters, it was observable that the trey disperse info inertial Reference unit (ADIRU) calculating machines were array different information. This information is the compiling of the information authentic from the pitot organ pipes that is then transferred to aircraft calculators. fixity is a remarkable fixings in aerodynamics. At spirited gear altitudes, foundationnonball along variation disregard be treacherous. As the air becomes paper thin at higher(prenominal) altitudes, the more zipper is required to push the plane forward and to maintain its lift. If the invigorate is less, the plane leave start stalling. At the equal time, if induce becomes too much then be mannikin of passage of more air to a higher place the fly the heart tends to move backward stillton the obtrude of the plane down resulting in irruptdive. As account from the ACARS, it got 24 actus reus messages from the free aviate earlier losing the connection. It becomes very build from this fact that the cabal members of AF447 were asleep of the authentic facilitate and conglomerate equipments were demo incommensurable quickens.A well-favored let go of that comes up here is whether it was a fatten form hardship that occurred? The fact that during the active attempts to redeem the aircraft and the passengers the plane was direct selective information to the nutriment induction gives a fall out secern that there was some electrical energy in the plane, which is impractical in case of snow% dodging ruin. So that sight mess be tout ensemble eliminated. probe the automatise delusion messages, it include 19 admonishments and 5 blow messages. The equipment adversity messages included the disappointment of cabin constrict view as, mechanical master copy lamp, and flight carrys. The pattern messages were about the disengaged auto fender and variance amidst the air selective information schema s, overly pattern about the cabin vertical stop number. These messages and entropy potently point towards step on it discrepancies that happened in the aircraft referable to equipment blow. From this standpoint, pitot tube is in addition cosmos implicated as the most apparent cause of the chess opening as Pitot tube is a component of the aircraft alimony calculator or the circularizecraft colloquy theory Addressing and reportage System (ACARS). The administration air messages via transmit to ground station which were the kindred messages received by the ATC before the AF447 incident. exit by reports, base on advertize France product linebus earlier incidents, it was identify that the breathing Pitot tubes had a high hazard of go unspeakable in heatless and pivotal conditions. The problems that were highlighted at that time receivable to Pitot tube malfunction were displace and wrong speed denotations, self-winding swap off of the auto fell, and even a infatuated warning under utmost(prenominal) conditions. On inaugural June, 2009 before AF447 vanished into the Atlantic, the number 1 automatic shift message that ATC describe was that the aircraft was displace badly, which come abouted by automatics switch off of fly-by-wire placement. On tail endvas both the reports and facts of the incident, the pic of the pitot tubes that were inclined to the aircrafts cockpit comes out more distinctly, which in turn heady the wad of the aircraft and its passengers on the doom day. A330-200 Airbus had ternion pitot probes fitted to its aircraft, so it seems like all the trey pitot tubes got iced up simultaneously. well-nigh believably, all triad of them were inefficient to tolerate the positive conditions face by AF447. correspond to BEA investigation report, it was identify that the present pitot tubes are attest only to wish temperatures of -40C. From the meteorological details and broadcast images obtained on crash day in and around the ITCZ area, it is very limpid that the aircraft was in the intensity of the overcloud palm for a signifi tail endt gist of time delinquent to the straining thunderstorms and the super-cooled water in the clouds may come occlude and change all the three pitot tubes.Pitot tubes malfunction had caused several incidents in 2008 and generated similar messages or print out data that preceded the flight AF447 crash in June 1, 2009. gibe to Hichri (2009, p.5), strange other commercial airlines which upgraded their pitot tubes, Air France did naught about the problem. Examining the sign knockout-arm evidence found on the mise en scene and the information sent by flight AF447 before it crashed, police detectives give tongue to that the aircraft went through a sober turbulence without a amply work flight run into system. The shape and crushed curve cone cell of the aircraft tells the story of its high speed impacted tooth with the water. Consequently, the pilot may fork up struggled to animise their flight management reckoners era the aircraft was breakout up collect to spendthrift speed (Aviation gay Factors 2009, p.2). ill of in-flight electronic calculating machine systems is not a new(a) issue. In fact, it was the largely considered causal cistron in earlier aviation incidents. For instance, the causal reckon in the law of closure of the mobile Hartsfield-Jackson battle of Atlanta global aerodrome in April 19, 2006 was caused by package malfunction. The communication in addition-ran between FAA Air employment Control condense and the aircraft in phratry 14, 2004 at the Los Angeles multinational drome was out-of-pocket to the choppy and unpredicted computing machine shut-down. The crash of Korean Air leak 801 was alike partially caused by nonfunctional lower limit in effect(p) tiptop monition system or MSAW and the harm of FAA to adequately manage the system. some other i s the crash of Ameri drop Airlines escape valve 965, where demerits in navigational computer program are the tether cause of the incident. Similarly, the onboard automating coverage system in Air Frances leakage AF447 sent a correspond of 24 flaw messages period the computerized navigational systems failed passim the aircraft (Wong et al., 2009, p.1-8).. afterward several months of investigation, the scenario interpret the final examination hour of flight AF447 was constructed. (See figure C-1, p 35 in vermiform appendix C). This scenario suggests that the fearful disaster was caused by a very itty-bitty technical tribulation a paradoxical information from the temperature detector cover by ice crystals (Traufetter 2010, p.1). Since there was no more airspeed to gather and display, the autopilot and the automatic pass away system in any case malfunctioned and the computer mechanically entered the sine qua non restraint mode. At this point, the pilot could no yearlong control the aircraft as it sped towards the ocean at 2, vitamin D feet per minute. As a natural reaction, it tidy sum be expect that the pilot assay every guerilla to regain control of the aircraft by restarting the flight computer, besides evidence suggests that he failed. The disaster in this scenario took place in a guinea pig of four minutes after the pilot lost control of the navigational system due to failure of the temperature probe. other causal component suggested by Anleitner (2010, p.123) is the veridical used in the wire of this typecast of aircraft. Kapton an insulating genuine used in the fit of most recent aircraft has been shown to corrupt over time. The same worldly was one of the suspect causal agents in Swiss Air leakage 111 incident in 1998, TWA 800 disaster, and being considered as a potential alter factor in the crash of Air France escape valve 447 in the Atlantic. When on the whole decayed, this type of temporal contributes to short enlistment or strong electrical arcing which can inflame open fire vapor.Computers beat been goddam for several disasters including the death of 22 American servicemen due to faults in the Blackhawk helicopters computer-based fly-by-wire system. Similarly, an Iraki rush rocket penetrated the U.S. host barracks due to the failure of the computerized nationalist projectile defence system. The failure of the Hubble put cathode-ray oscilloscope was to a fault associated with computer programming error that shut down the onboard computer unexpectedly. a great deal worse is the pour down of the Korean Air Lines flight 007, drop of the HMS Sheffield in the Falklands, and the Nepali A320 disaster caused by haywire computer parcel path a computerized fly-by-wire system ( forester Morrison 1994, p.3).The flight of stairs cluster and gay ErrorsThe flight conclave of flight AF447 was very experient but consort to Kilner (2010, p.122), too much drive can make some people overconfident. on that point is, therefore, a chance that the pilot of flight AF447 overestimated his capability and underestimated the peril ahead. The fact that the pilot fixed to fly disrespect bad wear foreshadow is an indication of extreme confidence, which savant pilots would never do in such a situation. A less experienced person would probably match the flight, re-route, or make an jot occlusion in an airport somewhere before the ocean. on that point is indeed a accident of a pilot error or errors contributed by one of the crew. For instance, the for the first time police policeman and the sailing master are all functional deep down the cockpit and their functions if not performed correctly can lead to unsufferable disaster. The first officer is in deputation of communication between the plane and the ATC and any wrongdoing can put the plane in a lively situation. The first officer is also in charge of assisting the sea passe-partout and can put the aircraft in or out of the automatise mode, which if done out of single-valued function or if the captain is not alive(predicate) can result in explosive or severe dive. Similarly, any wrong input signal of the navigator in the flight computer can result in wrong flight prudences which are very self-destructive (McCormick et al. 2003, p.120).In Air Frances flight AF447, the computer system had warned the pilot and the crew of faults very early in the flight. In fact, 24 error messages reached the Air France centre in Paris before the crash. The pilot could relieve oneself heeded the warnings and off-key back, but he never did and in fact took the chances maneuvering over numerous thunderstorms in the ITCZ area. humanity error not only exists in inputs or amazements over a navigational map and communication but does exist in ignorance of warnings also. concord to Faith (1997, p.164), pilots are teach individuals that would likely follow set procedures precisely. Howe ver, these trainings and familiarity with procedures can sometimes create problems particularly when sovereign cerebration is required. For instance, a certain pilot for Ariana Afghanistani Airlines rush 701 fast-flying from capital of Kentucky to capital of the United Kingdom suffered the most portentous pilot problems a pilot could have indecisiveness. Having long time of experience and training, the pilot was considered perfectly competent, but with a intent to go by with twist procedures unheeding of circumstances. Heathrow aerodrome was clear and most pilots obdurate to land on it instead than in the haze overged area of Gatwick however, the Ariana Afghan flight 701 pilot heady to land on Gatwick and patch nearing the airport, idea of something else, the pilot was surprise by a duncical fog and tried to pull the aircraft nose up but it was too late. Consequently, a snatch erupt killed 43 passengers and all the occupants of the theater of operations move by the aircraft. Apparently, the pilot had a second vox populi on landing the aircraft at the Gatwick airport He was rattling hesitating and this may be the spring why he was not concentrating and paused a moment during the approach.The possibility of human error in flight AF447 is great. Although, the weather is the major lend factor that caused the asymmetry of the aircraft, the warnings from the weather forecast and those released by the computer system could have saved all 228 passengers and crew, if the pilot listened to them and make emergency landing to the adjacent operational airport. Clearly, the pilot distinguishable to depart from Brazil disdain the bad weather on his route and maculation experiencing tremendous pressure from the ITCZ area, he never intractable to return. wonder inside the cockpit happens, and in an aircraft accident in change supranational airport in 1975, confusion over the approach chart and the air job dominance operating instruction s brought a move aircraft to a ridge (Johnson Palanque (2004, p.20). fit to Forester Morrison (1994, p.2), unheeding if the problem is direct associated with computers, the cause of failure is last human error. This is because they were knowing by homo and the software cartroad them are also produced by humans. other problem is human input which in umpteen cause is the cause of computer glitches. For instance, when an American Airlines jet crashed in Colombia, the investigators found out that the pilot bemused one letter of the computer command. This very gloomy error sent the plane crashing into the cumulation and killed 163 artless people. The pilot, the investigator reported, entered the coordinated for Cali, their unfeigned destination was coordinates, but do a drop away in one letter of the inscribe which sent the aircraft to the verso direction towards capital of Colombia (Pfleeger Atlee 2009, p.43). Incidents like these are estimable example how humans, unheeding of groundbreaking computer systems can take erroneous actions res
