"" Often, experience, we realize that an accident never a cause, but there has roots causes, aggravating causes, there are major causes, there is a sequence of events that the accident happens ""
Sophie Desjardin, euronews:
Bertrand Vilmer you are an expert in aviation, a former test pilot yourself. It is still early to draw conclusions about what really happened that morning over the white valley in the Alpes de Haute Provence.
We know some things, however, including the fact that the pilot did not a distress call, but the plane seems to have fallen in stages, what could this imply?
Bertrand Vilmer expert in aeronautics:
There are two ways to make a distress call when you're in an airplane. There is a radio signal that begins "mayday mayday mayday" and there is the activation of a transponder which is a transponder that allows the ground controller to characterize extremely clearly on his radar does the unit is in distress. Here, the fact that from 38,000 feet for minutes, because we talk about 12 minutes between the time he left his flight level and when there has been the impact it There was no radio contact, it may not be surprising. Simply because when you have a problem in a plane, the first thing we did was to ensure control of the unit. Once assured the trajectory of the camera, the balance sheet is made of the failure and try to reduce the failure and then once this is all done if you have the time and if the apparatus allows it, then communicates.
Sophie Desjardin, euronews:
Is it that one can think of a depressurization?
Bertrand Vilmer expert in aeronautics:
In an aviation accident, there are three possible causes. Three families of possible causes. There are technical reasons, the material to speak simple, there is the environment of the weather, birds, power lines, etc., and man, man. Often, experience, we realize that an accident never a cause, but there has roots causes, aggravating causes, there are major causes, there is a chain of events that the accident happens.
Sophie Desjardin, euronews:
The plane in question was put into circulation in 1991, so he was 24 years old, is that it is old for a plane?
Bertrand Vilmer expert in aeronautics:
The answer is no. Not if it meets European service standards. First Airbus is an aircraft that entered service in 1988, there are more than 6,000 flying right now and a little more than 10,500 who are under order or delivery. It is a device that is extremely widespread. It has extremely strict maintenance constraints
Sophie Desjardin, euronews:
But 25 years is the commercial operating limits not?
Bertrand Vilmer expert in aeronautics:
Ca, what are the limits of own companies, but from the moment a device receives its certificate of airworthiness and where the workshops that maintain this unit, which are authorized workshops, so the device can fly.
Sophie Desjardin, euronews:
Lufthansa had sent to its subsidiary Germanwings last year, it is a common practice for end of life had to be given to low-cost subsidiaries?
Bertrand Vilmer expert in aeronautics:
What is possible is that the company policy is to highlight new aircraft on routes that are most profitable and popular, which is quite logical commercially. Now it has no influence on the ability of the device to not fall down.
