WASHINGTON (AP) - At least 12 flights, recent US aircraft, damaged equipment, the pilots can not, they know how to quickly fly, federal investigators have discovered. Similar failures, believed to have played a role in the Air France crashed into the Atlantic Ocean, killing all 228 people in June. This finding suggests that the problem is more extensive equipment than we originally thought. This gives new urgency to airlines already penn avionics have to replace air sensors and figure out how to go undetected errors, despite safety systems. The equipment failures, penn avionics all involving penn avionics Northwest Airlines Airbus A330 aircraft, is short, and noting that security officials after the French aviation accident investigation began - in Rio de Janeiro to Paris flight - and two other recent failure in flight. Failure penn avionics describes a person familiar with the situation only to investigate who requested anonymity because they are not entitled to public. Although the speed of the car using a tire rotation speed to calculate an aircraft rely on sensors known as Pitot tubes to measure air pressure changes. Computer explained that the speed of information. The car broke the speed may be a little penn avionics more inconvenient, many airplane control systems rely on accurate speed information to work properly. Air France flight as fatal, the Northwest incident and two other newly discovered fault is investigating the reliability of the European electronics giant Thales sensors all sensors involved in aircraft penn avionics made by Air France crash triggered a peak in question and replace them. Many companies, however, only to replace them with another Thales model. Because it is very clear that the problem is more widespread, Airbus and European regulators for companies to replace at least two of the three sensors each aircraft model made in North Carolina Goodrich plane was allowed to continue Flying while the switch is made. Thales officials declined to comment. The company had previously penn avionics said its sensors Airbus specifications. Northwest event when the company found that Delta Air Lines, which merged last year, the Northwest, 32, close to the person's investigation to review the flight data archiving fleet of Airbus A330 aircraft, said. All of these events occurred in the Intertropical convergence zone, extending to 5 degrees north of the equator 5 degrees south, and all the aircraft landed safely participate, they said. Aviation experts said the findings could provide clues to cause of Air France Flight 447 crashed in the Atlantic Ocean en route from Brazil to France on June 1, and what can be done to prevent future tragedies occur. French investigators have focused on the possibility of flying ice sensor 447, and issued false information, high-speed computers, aircraft hit the thunderstorm about thirty-five thousand feet. The important part of the investigation focuses on 24 automatic email aircraft in its last minute. They show the autopilot is not feasible, however, it is unclear whether the pilots shut it off or shut down because of a conflict airspeed readings. After three weeks, the French aviation accident, the National Transportation Safety Board announced it was investigating two other A330 flights experienced a loss of airspeed data. Kagoshima penn avionics in Japan last June 23, when the Northwest flight, heavy attacks and unrest autopilot outside. According to the National Transportation Safety Board report, the high-speed data began to fluctuate. The aircraft's pilot was going too fast reminder. Autopilot and other systems began to shut down, to control almost all of the aircraft in the hands of the pilot, which is usually only in the event of an emergency. May this year, one belonging to Brazilian company TAM Airlines lost airspeed and altitude data while flying from Miami to Sao Paulo, Brazil. Autopilot and auto power off and also take over the pilot, the National Transportation Safety Board report in accordance with. The computer system back for about 5 minutes. '' It's two cases, we know the crew handled efficiently, we believe penn avionics that this happened in Air France and may not be effective treatment, '' said Bill Voss Flight Safety male president, Foundation in Alexandria Alexandria, Wa. Aviation security think tank. A spokesman Morgan Durrant only other US airlines A330 aircraft, American Airlines said it did not see a similar problem penn avionics in its fleet of 11 aircraft. Delta / Northwest Airlines and American Airlines recently completed a new pipe to replace the old Thales Thales tubes. The company said that they are now replaced by a solid tube. In June, the Air France pilots' union urged its members to refuse to fly the Airbus A330 and A340, unless their Thales sensors penn avionics replaced. The Federal Aviation Administration has not issued a safety directive, but a spokesman for Brown said the agency hopes to have one soon.
