...Those rearcrew who are ex-mil will probably still try to take as much of an active part in any letdown because that is the way they are wired..
The ex-mil rear crewman I have had always know the track and distance to the next waypoint, and the minimum height on that sector, and on reaching that waypoint, which direction to turn, and on to what heading. They follow the procedure all the way with their finger on the map. If I deviate from anything they expect, they will bark at me.
