Question on arducopter 3.3.3

Hi guys I am using arducopter 3.3.3 and I am pretty happy with it, but I would like to understand something which is still not clear to me,
From reading on the arducopter forums, if I understood correctly, the FC tries to recognize the flying and the landing condition… Is there a way from the logs to understand if the FC recognize the landing moment ? If yes which values are showing this ?
