DH 50 Feet or Less
•The first four Automatic Landing limitations must be observed.
•All three autopilots must be engaged and the autoland status annunciators must show LAND 3 at and below 600 feet.
•The autopilot must be coupled to an ILS which conforms to the requirements of ECAC Document 17 Category III operations.
A change from Land 3 to land 2 indicates a single failure in the autopilot system.
Thanks guys. LAND 2 = Cat 3A on the 757 ASA Bealzebub just to add a bit more confusion !
Unless your Cat 3A minima is above 50ft, I am curious how you bypass this AFM limitation.
