What is fail passive?
AP disengages without any significant deviation in trim, flight path or attitude. After a failure either the landing is completed manually, or a manual go-around is executed if visual references are not sufficient.
What is fail operational?
An automatic landing system is fail-operational if, in the event of a component system failure below the alert height, the approach, flare and landing can be completed automatically. In the event of a failure, the automatic landing system will operate as a fail-passive system.
