In italia la maggior parte delle compagnie che operano aerei al di sopra delle 45500 kg o 60 pax hanno come policy la presenza di un FFAA durante la mancanza di uno dei CM. Poi se non lo fanno sempre questo è un altro punto.
Cmq la Lufthansa NON ha questa policy. Vedi sotto (non sto a tradurre)
On Mar 26th 2015 the States Attorney of Marseille (France) reported, the first officer was alone in the cockpit. The first officer was not talking, only normal breathing could be heard after the captain departed the cockpit. The captain was not able to get back into the cockpit. The first officer initiated a rapid descent, there was no reason to initiate the rapid descent, there was no reason to not communicate with air traffic control, there was no reason why the door wouldn't open. With the current information it can be said, that the breathing of the first officer is not consistent with someone suffering a heart attack or other health issue. Other than that there is absolute silence in the cockpit, screams are heard only in the last few moments. There were no words heard during the last 10 minutes of the flight. The states attorney thinks the first officer intentionally did not open the door.
In a joint press conference on Mar 26th 2015 Germanwings and Lufthansa stated they are shocked having to accept that according to cockpit voice recorder the first officer locked the captain out of the cockpit and deliberately steered the aircraft into terrain. Pilots undergo detailed assessment and psychological tests. The first officer started training in 2008, worked as a flight attendant, continued training after undergoing another assessment, passed all tests and started his pilot career as first officer on the A320 in 2013. The CEO of Lufthansa explained, that if after the extended code to enter the cockpit has been entered, the pilot in the cockpit receives a signal and has the ability to open the door or lock the door. If the pilot in the cockpit does not react at all, the cockpit door opens upon entering the extended code after some time. If the pilot in the cockpit selects to lock the door, the door remains locked for 5 minutes. Within the entire Lufthansa group there is no standard operating procedure requiring another member of the (cabin) crew to enter the cockpit if one of the pilots leaves the cockpit. The captain was permitted to leave the cockpit in cruise flight, e.g. for a toilet break.
