When the runway is in excess of 8000 feet in length, a midpoint RVR sensor is required in addition to the touchdown and rollout sensors for CAT II operations below RVR 1600. (AFMAN11-217 10 JUNE 2019 19.3)

Automatic AIII mode arming requirements are satisfied when:
Automatic AIII mode arming requirements are satisfied when:
-PRI or IMC mode selected, and
-all required systems operating normally (AIII capable), and
-ILS frequency tuned on VHF NAV receiver No. 1 or No. 2, and
-radio altitude is greater than 500 feet, and
-TOGA mode not active.
To activate AIII ARM, push the STBY function key on the HUD control panel. When armed, “AIII ARM” is displayed on the standby mode display line and “AIII ARM” is displayed on the combiner. Approximately five seconds after the requirements for ILS approach criteria are satisfied, the AIII mode is automatically activated.
-

Can EVS mode be used on a CAT II or III?
The EVS mode can be used with most other modes; PRI, IMC and VMC. The EVS may not be used on a CAT II/III approach (AIII mode). The EVS imagery overlays the mode display in use.
-
What do these messages in the HUD/HGS mean?
Displayed below 500 feet if approach monitoring tolerances are exceeded or AIII capability is lost.
-
Can you attempt an overweight autoland?
Autolands are not recommended for overweight landings.
(FOM 6.27)
Overweight Autolands Policy
Overweight autolands are not recommended. Autopilots on Boeing airplanes are not certified for automatic landings above maximum landing weight. At higher than normal speeds and weights, the performance of these systems may not be satisfactory and has not been thoroughly tested. An automatic approach may be attempted, however the pilot should disengage the autopilot prior to flare height and accomplish a manual landing.
(FOM 6.34)
-
Is the C-40 fail operational or fail passive?
Fail passive.
Fail passive refers to an AFDS which in the event of a failure, causes no significant deviation of airplane flight path or attitude. A DA(H) is used as approach minimums.
-
Can the HGS EVS image be used or displayed during an approach in Category II or III conditions?
No. The HGS EVS image shall not be used or displayed on the Head-Up Display (HUD) or Lower Display Unit (DU) during approach or takeoff in Category II or Category III conditions. (FCOM L 10.5)
-
Can an FP make a CAT II or III approach in actual CAT II or III weather conditions?
