I have tried over and over to execute an autoland on the tutorial and it always says NO AUTOLAND. Before that it says single channel in yellow on the PFD. I've followed the steps to the letter and it just doesn't work. Any ideas of a reason why it won't work? I've also tried at other airports and the result is the same. Just curious.

Both Flight Directors On?Both Courses Set?Both Nav Radios Set?Both Autopilots On?ILS Runway selected in FMC?
