Autopilot/autoland
Need some facts from real operators. When does the autopilot disengage on autoland when the full system drops out? On the 747, how far can you go down the slope with only 2APs engaged? On the A320, which starts with only 2 APs anyway, how far can you go with one? And, finally, how far can you go on an ILS with no autoland available?
Thanks in advance. All my written source info is unclear/confusing
