Statistically everybody will encounter 3 to 4 times in his life a very difficult period.. .. .Death of his father, loss of a child, house on fire, serious accident happening to the children, divorce etc.... .. .All the above should not lead to the loss of licence, if that would be the case we would no longer be able to fill the flight deck.. .. .There is really only one answer to the problem and that is “mutual thrust.”. .. .In my airline we have a good relationship with the medical and ops department… if you feel unfit to fly...just tell them and they will help you.. .. .Basically if you managed to get trough the psychological tests, obtained an ATPL rightfully, you proved that you can handle a reasonable amount of stress the above mentioned problems should not lead to the loss of you licence.. .. .And last but not least, the chief pilots are, normally speaking, people with some life experience as well, meaning they went trough some of the above mentioned experiences themselves and should be able to help you as well.. .. .A clever manager will actually, in a discrete manner, get the message across during the flight training. .. .Remains the fact that operations in a multi crew environment are fail operational…..incapacitation calls and checks are pretty standard and are part of every days life.. .. .The real danger is when the cultural environment does not allow that these things are openly discussed between the pilot and his chief or doc.....that's were you will find the problems.
