1) In triple autopilot system has an ILS receiver failure on lacaliser approach : (a) Aircraft continue to autoland (b) Autoland is discontinue and GA is initiated (c) revert to cat II.
2) If during autoland system has an ILS receiver failure Before Alert Height, the scenario: (a) Continue Autoland (b) Autoland is discontinue and GA is initiated (c) revert to Cat II
3) If during autoland system has an ILS receiver failure After Alert Height, the scenario : (a) Revert to Cat II (b) GA is initiated (c) Autoland continue with no failure annunciated.
Thanks in advanced.
