and says that the door is open. and if i release it, it goes back to the normal position. and the norm means locked? that is correct. reporter: according to the airbus operations door there is a keypad that allows the entry if you noeknow the code, but if the person inside switches it to lock the keypad won t work for five minute and there is another that goes beyond five minutes. and ki the key pad and hold it in the lock position, and he cannot use the keypad or anything, because it can t go in. reporter: and so to keep the co-pilot out, what do you have to do? if he knew the keypad number i hold lock and he can t get in. and can you manually fly this and hold the lock button? oh yes, easy. reporter: but then that s ais a purposeful act? very much so. reporter: again and again, we fly through the scenarios in
ways an airplane does what this airplane did. he had to actually keep the pilot outside of the cockpit door by holding down a button that overrides the code path. and he had to reprogram the fms. let me explain this because there are literally three buttons, unlock normal and lock. correct. he had to literally put it in the lock position. in the override position to override that code. that pilot from trying to get in. that s correct. so that means the pilot otherwise would have been able to get in. nor do i think the co-pilot on his own would descend in what is a gradual descent right? certainly not that stage in the flight. they were at cruise. they were at 38000. they were expected to stay there. the next thing we know the flight management system is being reprogrammed to start to descent all the way down to the surface. brian do you agree with that? it seems to me that there s too many the plane didn t descent didn t make this descent on its own. obviously the

the descent of the plane. the prosecutor said, this action could only have been voluntary. and then later, the captain is heard pleading to get back into the cockpit, but the co-pilot, heard breathing normally until the plane crashes, does not react. you can hear the commanding pilot ask for access to the cockpit several times, the prosecutor says. he identifies himself, but the co-pilot does not provide any answer. it should be noted that the airbus 320 mechanism for the cockpit door allowed someone inside the cockpit to lock the door in such a way that the normal procedure for getting in from outside the cockpit is disabled for five minutes, as depicted in the airbus training video. the video also shows an emergency procedure for gaining access to the cockpit if the pilot is incapacitated. the captain moves the toggle switch to the lock position. the open light remains extinguished. now if we look at the code pad, the red light is lit, confirming the door is locked. be careful, aut
