Question

I have a few questions regarding the German Wings crash (Flight 9525) in the French Alps.

A) Why was it not possible for the Captain to get into the flight deck by entering the personal code?

B) Has there been any operational changes following the crash to prevent it from happening again

 


Answer

A) Why was it not possible for the Captain to get into the flight deck by entering the personal code?

The unlocking features of the flight deck door may be different from plane model to plane model, but we think the basic concept is the same on most planes. If  the unlock code is entered there is an alert activated on the flight deck (most likely both aural and by a red warning light). The auto unlock is time delayed so after the alert is activated the auto unlock can still be denied from the flight deck. If entry is denied the ability to use the unlock code is disabled for a certain amount of time. So to sum it up, entry to the flight deck from the cabin can be prevented from the flight deck indefinitely.

B) Has there been any operational changes following the crash to prevent it from happening again?

The Aviation industry is highly focused on making flying as safe as possible and rest assured that there is willingness to learn. Following The German wings accident the best ways of preventing it from happening will be introduced but we cannot comment on the details of all of the procedures.
