PARIS, France – I met up with affable Airbus flight test engineer Fernando Alonso a few minutes before our scheduled 15-minute interview in the cockpit of the first A380 to fly.
Jim Boulden takes to the flight deck.
Alonso has worked on the development of nearly all the airplanes produced by the 40-year-old aerospace giant. He proudly recalls that he was the engineer on the first A380 flight back in 2005. He also reminded me not to touch any buttons without asking first. During our all too brief conversation he explained the benefits of fly-by-wire technology first introduced by Airbus in the 1980s and now used in all new planes. When the pilot or auto pilot wants the plane to bank or descend or whatever, in the older planes he or she would actually manipulate the wings or tail through levers and pulleys. Now the computer does all that by interpreting the actions of the pilot or auto pilot. With the crash of Air France 447 on June 1 (an Airbus A330) still a mystery the possible actions of the pilot in response to any potential systems failures is a hot topic. Alonso explained to me that fly-by-wire works by interpreting the data the computer receives on speed, weight, fuel consumption etc. So, the computer would then give back certain duties to the pilots if there were computer or systems failures. I asked him what - as an engineer - his gut instincts are about what brought down the Air France plane. He said not knowing was the worst part of this tragedy for an engineer as the industry can learn so much about safety and can make changes accordingly. But he is confident lessons will be learnt from Flight 447. Posted by: CNN Correspondent, Jim Boulden |
