I am sure it must have been a very unpleasant landing for the passengers (and crew) on board a United A320 that made an emergency landing in New Orleans yesterday.United flight UA 497 was on the way from New Orleans to San Francisco when it encountered severe technical difficulties. Apparently, there was smoke in the cockpit and the pilots "lost all instruments" according to a Bloomberg article. Other reports mentioned that the Airbus's primary flight computer wasn't functioning.
As U.S. media love to do (see Sullenberger Hudson landing), the pilots were quickly portrayed as heroes. Big U.S. broadcasters described this landing as a "blind landing," which is a very misleading term as non-experts may believe the pilots didn't see anything. This is not true - blind landing means that the pilots do not have any working navigational instruments. They can still see when they look out of the cockpit.
United's A320 was still functional and returned to New Orleans. With help from the folks in the tower, UA 497 performed a visual landing, which pilots do every single day at airports across the world (e.g., at DC's Reagan Airport). The plane's fly-by-wire system worked, the flaps were retracted and the landing gear worked as well. Pilots should be trained to handle situations like these.
The incident was likely caused by a cable that was heating up and starting to burn, causing the instruments to black out. This has nothing to do with Airbus's technology, flight computers or fly-by-wire system and could have happened on any plane.
