The Last autoland I did was on a 2 day old 319 and it was a real cruncher.
I was very glad that I'd told the pax it would be an autoland!
You can tell if you sit near the front of the aircraft and listen out very carefully.
When we take out the autopilot there is always an alarm of some sort.
If you hear the alarm on approach then the autopilot has been taken out. If you hear the alarm on the roll out it was an autoland.
Of course some folk hand fly from a long way out and it's more than possible that the cabin crew could be talking on the PA when the AP is taken out.
The cabin crew can usually hear the alarm so I guess front row passengers should be able to.
