So no they aren't screwed if the computer Fks up. It is a fly-by-aircraft but the pilots can override it if they need to. I'm no expert, but I assume that if the pilots to want the fly manually the first thing they do is tell the computer flying the plane to give them manual contol. Therefore if something severs communications between the pilots and the computer, they can't do that and the override fails. That is my thinkng. I'm no expert either but I would have thought it would be quite easy to override it in that particular situation by simply cutting off the power supply to the computer, by pressing a switch or unplugging a wire for example. |

They cited a leading expert on this new plane telemetry tracking system, I guess it's a pre-blackbox tech, sending a constant stream of data to satellites. They're saying it was sparked by an electrical fire, taking the computers out, all 7 apparently. They lost elevator and rudders. Sats were saying under the front lav is where all the hardware resides, smoke starting filling the front lav. Quoting: Itshotherealways Will try and find a link as soon as it's up. Yet they're saying it was "terrorism". I guess when you constantly blame everything on terrorism it justifies the never-ending neo-con military crusades. My toaster malfunctioned and ISIS has claimed responsibility. So let's invade Syria. Government Logic 101. |

Airbus have a Joystick to "fly" . . . those inputs are the way to move surface-controls . . . no backup system if "joystick data" is a no good for the cpu´s. Burn the cables and that is it. Depending on the configuration pilots can over-ride cpu´s commands some or all. |

This means that the mechanical linkage between control column and control surface has been replaced by electrical wires. Just like the Boeing 737, the Airbus A320 flight controls are divided into primary and secondary flight controls. Both the primary and secondary flight controls are controlled by a total of 7 computers. The primary flight controls fitted on the aircraft are controlled by sidestick inputs and digital processing by the Elevator Aileron Computer (ELAC), the Spoiler Elevator Computer (SEC) and Flight Augmentation Computer (FAC). When the primary flight controls on the Airbus A320 are being operated, electrical signals from the sidestick or Flight Management and Guidance System (FMGS) are send to the flight control computers before being passed to the flight control hydraulic actuator. .

That plane was at 37,000ft so it would be in many pieces before it hit the ground. Quoting: Anonymous Coward 70589524 unless it was a fast controlled descent, so the pilot could fly at 100 ft. above the deck, under the radar, and land in Cypress. . |

Nothing will happen to AirBus, other than a hefty fine and payoff to all the families. Boeing didn't go out of business when the Alaskan Air flight out of Cabo went nose down with their employees on it flying back to SeaTac due to the elevator screws breaking in the tail section and crashing into the Pacific. 3 mins of complete hell.

The pilots can instruct the computer to give them manual control, if they can commnicate with it. |
