flight deck is designed so that a quick analysis and decision can be made for
virtually all non-normal or fault situations using the crew alerting system and
autoland status annunciation.

If the flight crew is aware of the airplane equipment requirements for the
approach, the following can be used for any AFDS fault indication:
Above Alert Height
Immediately after recognizing the fault from the crew alerting system, instrument
flags, or engine indications, check autoland status annunciation.
• if the autoland status annunciation has not changed, and the equipment is
not required for the approach or can be switched, (e.g., flight director),
continue the approach
• if the autoland status annunciation has changed, or the equipment is
required for the approach, adjust to the appropriate higher minimums or
go-around.
At or Below Alert Height
For any EICAS alert, continue the approach to an automatic landing and rollout
unless the alert is accompanied by a master caution. The pilot should not intervene
unless it is clearly evident that pilot action is required.
A thorough fault analysis was included as a part of the fail operational
certification. Below 200 feet AGL a safe landing and rollout can be made with any
probable failure conditions.
Flight crew alerts (messages, lights, or aurals) may occur at any time during the
approach. Below alert height, multiple autopilots protect against any probable
system failure and will safely land the airplane. The pilot should not intervene
below AH unless it is evident that pilot action is required. If a fault affects the
autobrakes, assume manual control of braking. Accomplish related procedures for
system faults after rollout is complete and manual control of the airplane is
resumed.
If the autopilot is unintentionally disengaged below alert height, the landing may
be completed if suitable visual reference is established.
If a go-around is initiated with the autopilot disengaged, press the TO/GA switch.
If the TO/GA switch is not pressed, the flight directors remain in the approach
mode.
