![]() ![]() To be fair, we are waiting for the results of the flight’s data recorder, which records the pilots instructions sent to any electronic systems on an aircraft. If one person takes 149 people with him to death, it is not suicide.” This has led officials to believe that the co-pilot deliberately set in motion the events that caused the crash.Īsked whether this was suicide, Lufthansa CEO Carsten Spohr said at an afternoon press conference, “I am not a lawyer. Officials say that the junior pilot used the flight management system to start the descent of the plane, which, at the altitude the flight was at, could only be done voluntarily. The last sounds on the recording were of the senior pilot trying to break the cockpit door down, followed by the screams of passengers right before the plane crashed on the side of a mountain in the French Alps, killing all 150 people on board. Throughout the commotion, nothing was heard from inside the cockpit, except for Lubitz’s breathing, officials say. Sonderheimer tried to regain entry into the cockpit for 10 minutes while the plane was in a steady, yet sharp, descent downward. He is heard yelling for Lubitz to open the door on the flight’s cockpit voice recorder, which was analyzed by crash experts on Wednesday. When Sonderheimer tried to get back into the cockpit, he was unable to gain entry. Apparently, the junior pilot, Andreas Günter Lubitz, 27, was left alone in the cockpit while the senior pilot, Patrick Sonderheimer, left the cockpit, presumably to go to the bathroom. With the CCQ, pilots can start flying in revenue flights in a short period of time.Lufthansa, which owns Germanwings, confirmed on Thursday that the crash of Flight 9525 was due to “deliberate” pilot error. This is the traditional route which is quite expensive and time-consuming for the airline. Once the pilot passes the line check, then only can he/she fly with line pilots. The line check is also conducted in a revenue flight with an instructor or an examiner. Each line training flight is assessed until the instructors release the pilot for a line check. Once type rated, the pilot is required to undergo line training in the airline where he/she must fly with instructor pilots in normal passenger flights. To pass the type rating, a skill test must be passed with a type rating examiner at the back of the full motion simulator. This is usually a 40-day course where the pilots learn new aircraft systems and procedures and fly the aircraft simulator. ![]() When pilots make the transition from one aircraft type to another type, they are required to undergo a Type Rating course. The main benefit for pilots is that it makes the transition from one Airbus aircraft to the other much easier. What benefits the commonality offers to pilots and airlines? But these differences are easily learned. There are some small differences even between the A320 and A321, with the latter being a little sluggish to control inputs. So, even when the aircraft is heavier and aerodynamically different, it behaves similarly. For example, the pitch control is a g-load demand, roll control through the side stick gives a roll rate demand, the rudder a side-slip demand etc. All Airbus aircraft starting from the A320 have similar control laws. The control computers are governed by a set of written codes which are called control laws. In the fly-by-wire control system, the pilot control inputs are detected by sensors, and these inputs are then sent to flight control computers which process the data and send it to the hydraulic actuators, which move the control surfaces to make the aircraft behave as per the pilot demand. The fly-by-wire system differs from the conventional flight control system in that it makes controlling aircraft much easier. The A320 is the first civilian aircraft with a digital fly-by-wire system. Picture: Airbus It all started with the Fly-By-Wire (FBW) technology
