737-800 Dual Channel Autoland

Any NG pilots with the Rockwell Collins enhanced MCP know what would cause both autopilots to disengage at 200 feet RA on a dual channel autoland approach and the NO AUTOLAND message on the PFD and HGS?

Dual autopilot engagement is possible, provided that both NAV receivers are tuned to the ILS frequency, APP mode is selected and the aircraft is above 800 feet RA. Something is causing both autopilots to disengage at 200 RA.

Ask your question in the simulator thread.

I have had this happen and on both occasions it has been a momentary rad alt problem.
