Hi Alex,
As I understand it “NO LAND 3” on C/R means Cat IIIb is not available, “LAND 2” means Cat IIIa is still available. “NO AUTOLAND” is the other caption that may be seen. Definitely only 2 A/P’s on the 737, we know this because the Collins MCP only has 2 A/P switches.
Airmen,
That would be my last step. If I went to Boeing with every question I had about the aircraft they would soon tire of it. However if it gets to that stage I shall post the answer here. We have a lot of 737 guys on PPRuNe, I just thought someone out there might know and it would be of interest to the others.
