Upon arrival at DA(H), or any time thereafter, any of the above requirements are
not met, immediately execute the missed approach procedure. When visual
contact with the runway is established, maintain the glide path to the flare. Do not
descend below the glide path.
Raw Data - (No Flight Director)
Raw data approaches are normally used during training to improve the instrument
scanflow. If a raw data approach is required during normal operations, refer to the
DDG or airline equivalent for the possibility of increased landing minima.
777-200 - 777-300ER
ILS deviation is displayed on the attitude display. ILS deviation may also be
displayed on the ND by selecting APP mode on the EFIS Control Panel. The
localizer course deviation scale on the attitude display remains normal scale
during the approach and does not change to expanded scale at approximately 5/8
dot, as happens with F/D and/or autopilot engaged and localizer captured.
Continue to cross-check the map display against the attitude display raw data.
Select VOR/ADF switches to display appropriate pointers on the ND.

The magnetic course/bearing information from the VOR/ADF pointers on the
navigation display may be used to supplement the attitude display localizer
deviation indication during initial course interception. Begin the turn to the
inbound localizer heading at the first movement of the localizer pointer.
787-8
The magnetic course/bearing information from the VOR/ADF pointers on the
navigation display or the mini map may be used to supplement the attitude display
localizer deviation indication during initial course interception. Begin the turn to
the inbound localizer heading at the first movement of the localizer pointer.
After course intercept, the track line and read-out on the navigation display may
be used to assist in applying proper drift correction and maintaining desired
course. Bank as needed to keep the localizer pointer centered and the track line
over the course line. This method automatically corrects for wind drift with very
little reference to actual heading required.
Large bank angles are rarely required while tracking inbound on the localizer. Use
5° to 10° of bank angle.
When the glide slope pointer begins to move (glide slope alive), lower the landing
gear, extend flaps 20, and decelerate to flaps 20 speed. Intercepting the glide slope,
extend landing flaps and establish the final approach speed. When established on
the glide slope, preset the missed approach altitude in the altitude window. On
final approach, maintain VREF + 5 knots or an appropriate correction for
headwind component. Check altitude crossing the FAF. Begin timing, if required.
To stabilize on the final approach speed as early as possible, it is necessary to
exercise precise speed control during the glide slope intercept phase of the
approach. The rate of descent varies with the glide slope angle and groundspeed.
Expeditious and smooth corrections should be made based on the ILS course and
glide slope indications. Apply corrections at approximately the same rate and
amount as the flight path deviations.
The missed approach procedure is the same as a normal missed approach. Flight
Director guidance appears if TO/GA is selected. Refer to Go–Around and Missed
Approach - All Approaches, this chapter.
AFDS Autoland Capabilities
Refer to the applicable AFM for a description of demonstrated autoland
capabilities.
777-200 - 777-300ER
Note: For autoland use flaps 20 or 30.

Note: For autoland use flaps 20, 25 or 30.
Note: Autoland should not be attempted unless the final approach course path is
aligned with the runway centerline. If the localizer beam is offset from the
centerline the AFDS ROLLOUT mode may cause the airplane to depart
the runway.
