During most of its long descent into the Atlantic Ocean, Airbus A330-203 was in a stalled glide. Far

The BEA says the doomed flight, which killed all 216 passengers and 12 crew aboard on June 1st, 2009, fell victim to technical faults on the Airbus A330 aircraft as well as inappropriate action by the pilots .
Apparently the faulty pitot tubes had been installed discount car rental rates on other Airbus models as well (A340, A330) and this super cooled water icing problem had already surfaced before this crash. The airlines were in the process of replacing the tubes, but unfortunately this plane didn t get the new tubes in time. Even with the faulty pitot tubes, the pilots just screwed up in their corrections. All they needed to do was keep the nose up a few degrees and keep the power setting to 85% and the plane would have maintained steady flight discount car rental rates until they were out of the storm- this is standard procedure in events where airspeeds aren t in agreement. When the incident first occurred, the crew got so many warnings from the plane s computer, it was probably hard to tell that they simply lost their pitot tubes. Automation might have made things worse in this event. Nevertheless, all of the defective discount car rental rates pitot tubes have now been replaced and the A330 remains one of the safest airliners around!
The FAA has been giving AIRBUS a free ride for years. Airbus has design problems with the aircraft s tail. An Airworthiness Directive was only issued by FAA last year, requiring Inspections and repairs costing 40 MILLION dollars. Did they fix the problem?
Fly by wire systems such as Airbus, using the side stick under ideal conditions is difficult at best to control at altitude. Add in night conditions and a melt down of the aircraft s computer systems discount car rental rates and the flight deck would be a confusing place to be in! Pure Hell!
A controlled simulator test was conducted after the accident of 447 and the crew was able to maintain level flight with basic instrument procedures using the ATTITUDE INDICATOR IA and a specific power setting.
Lastly the three pitot systems used by Airbus were defective and were not changed yet on the accident aircraft. Pitot systems have been known to fail. But it is unusual for all three systems to fail. Why would this system suddenly ice up now? A lot of questions with no answers.
The accident was caused by the co-pilot induced stalled discount car rental rates glide condition and remained in that condition until impact. To recover discount car rental rates from stall is to set engine to idle to reduce nose up side effect and try full nose down input. If no success roll the aircraft to above 60° bank angle and rudder input to lower the nose in a steep engaged turn. Pilots lack of familiarity and training along with system malfunction contributed to this terrible accident. Also the following contributed discount car rental rates to the accident
(3)lack of effective communication between the co-pilots discount car rental rates and the captain discount car rental rates which limited the decision making processes, the ability to choose appropriate alternatives and establish priorities in the actions to counter the stalled glide
During discount car rental rates most of its long descent into the Atlantic Ocean, Airbus A330-203 was in a stalled glide. Far from a deep stall, discount car rental rates this seems to have been a conventional discount car rental rates stall in which the Airbus A330-203 displayed exemplary behavior. The aircraft responded to roll inputs, maintained the commanded pitch attitude, and neither departed discount car rental rates nor spun. The only thing the Airbus A330-203 failed to do well was to make clear to its cockpit crew what was going on.Its pitch attitude was about 15 degrees nose up and its flight path was around 25 degrees downward, giving an angle of attack of 35 degrees or more. Its vertical speed was about 100 knots, and its true airspeed was about 250 knots. It remained in this unusual attitude not because it could not recover, but because the co-pilots did not comprehend in darkness, the actual attitude of the aircraft. The co-pilots held the nose up. If the co-pilots had pushed the stick forward, held it there, and manually retrimmed the stabilizer, the airplane would have recovered from the stall and flown normally.
Air France complained that the copilots did not have enough time to analyze the situation. Gravitational discount car rental rates stalled glide does not allow timeouts, to thoroughly discuss the situation to find out what went wrong. The co-pilots 37 year old David Robert and 32 year old Pierre-Cédric Bonin missed the cardinal rule that first they must fly the airplane, and after start analyzing the situation, since a falling airplane is not going to wait for them. If they did not understand the instruments, then instead of pondering on it they should have come to the quick conclusion that they did not understand those instruments, and apply the unreliable airspeed procedure clearly prescribed for that situation, which is a blind, given thrust and pitch setting for the given configuration, and let the airplane fly itself, and only after get to analyzing what went wrong, and by the time they finished, the root-cause (pitot icing) would have probably cured itself. It was the safe solution to the problem, but not applied.
The Airbus A330 performed discount car rental rates exactly as it was designed and described when the stall warning cut out at the end of valid values, except the co-pilots did not know it. Unfortunately, it happens too often with catastrophic results that pilots are not familiar with the systems of their own airplane, such as in the case of American Airlines 587 over Queens, which was clearly discount car rental rates the airline's fault.
Air France also argued that the stall warning system in the A330 is too "confusing". Every modern airplane is quite a confusing piece of machinery. It is full of buttons, levers, all kinds of red, yellow, green lights discount car rental rates with buzzers, and a host of other indicators and controls inside, which can look very confusing indeed, but it is the pilot's duty to reign on them, or not to be pilot.
Airbus A330-203 discount car rental rates is a new generation, highly automated piece of equipment with drastically simplified controls, displays, and instrumentation compared to older models. discount car rental rates Still, pilots with the same human capabilities as the ones on Air France discount car rental rates flight 447 could very well stay in full control in those planes, and many times acted heroically saving discount car rental rates situations much graver than where the plight discount car rental rates of Air France flight 447 started, such as United Airlines discount car rental rates flight UA232 at Sioux City, or Air Canada flight AC143, the Gimli Glider. If those pilots could perform well in those older, much more complicated aircraft in tougher situations, then there is no excuse for the co-pilots of AF flight 447 to be confused in a generally much simpler and easier-to-fly aircraft.
The Airbus A320 is a digital fly-by-wire aircraft as the flight control surfaces are moved by electrical and hydraulic actuators controlled by a digital computer. The computer interprets pilot commands via input from a side-stick, making discount car rental rates adjustments on its own to keep the plane stable and on course, which is particularly useful discount car rental rates after engine failure by allowing the pilots to concentrate on engine restart and landing planning. Some say the Airbus A330 is a "video-game" airplane due to its side-stick control, which does not match up in real hard situations. But who can say that after the successful ditching of US Airways flight 1549 on the Hudson River? It was an Airbus A320 with the same side-stick control, and it matched up with the hardest situation very well with an experienced 57 year old Captain Chesley discount car rental rates Sullenberger at the command. The Airbus A330 is not a video-game airplane, it is the airlines that make it a video-game by cutting corners, taking advantage of its superior automated capabilities thinking that it flies by itself, and no training and no knowledge of even the basics of the principles of flying is required in them for their pilots, as was demonstrated by the co-pilots of flight 447, who seemed to be incapable to react even on a basic level to the phenomenon of the aerodynamic stall. The co-pilots had not applied the unreliable airspeed procedure. The co-pilots apparently did not notice that the plane had reached discount car rental rates its maximum permissible altitude. The co-pilots did not read out the available data like vertical discount car rental rates velocity, altitude, discount car rental rates etc. The stall warning sounded continuously for 54 seconds. The absence of any training, at high altitude, in manual airplane discount car rental rates handling and in the procedure for "Vol avec IAS douteuse" (Flight with questionable Indicated Airspeed) caused this terrible accident. Evidently, it might not be what Airbus had on its mind designing the aircraft. They might have meant the best of the both, an airplane with superior controls, matched with seasoned pilots with superior education in the principles of flying and the handling of hard situations, best of the best, as airlines are prone to boast of their flying personnel, to represent quality improvement in flying safety by this pairing. Now, if this piece of equipment falls in the hands of the airlines who use it as a video game to save training costs, discount car rental rates telling only their pilots that "if the red light on the right side blinks, just pull the stick back as hard as you can, and let the system do the rest", they can get away with it as long as everything is normal, the airplane is good enough for that, but in unforeseeable situations, discount car rental rates such as the flight 447 en-route to Paris on that night, without any independent knowledge of flying in general, the video-gaming with the aircraft may ultimately come to a fatal end.
However, beyond the reasoning and explanations there is still some eeriness about the crash, taking in consideration that Air France flight 447 s pilots just sat there in daze squeezing the control stick, barely being able to do more than commenting on how the airplane was falling out of the sky until crashing into the Atlantic discount car rental rates Ocean, the arrival of the 58-year-old flight captain Marc Dubois in the cockpit not making much a difference either. The question might arise whether weren't the pilots in a mentally discount car rental rates incapacitating state of shock and disbelief? Whether discount car rental rates do or can Air France test pilots of how well they can keep their mental stability
