BOAC, you haven't missed anything. With a radio altimeter inoperative the autopilot will disconnect 2 sec after LOC/GS capture.Thats what I was saying.
This happened at 2000' and from memory aren't the platform altitudes 2000' at AMS?
More system monitoring and less blame seeking I think without sounding an note of apportioning blame. As I have mentioned on the previous post, I have been laughed at for guarding the controls in my early days as an FO. Startle factor/lack of situational awareness in the final moments of an approach have been the highest contributors to CFIT accidents.
As for system modes its either all out or all in. Lots of crews are reluctant to disengage the AT completely(except on a line check)even though the SOP says so!
