the pilot may perform a go-around or make a manual landing.
Note: All other EICAS messages are dealt with according to QRH procedures.
ILS Approach/Landing Geometry
The following diagrams use these conditions:
• data is based on typical landing weight
• airplane body attitudes are based on flaps 30, VREF 30 + 5 and should be
reduced by 1° for each 5 knots above this speed
• pilot eye height measured at point when main gear crosses threshold
• airplane ILS antenna crosses threshold at 50 feet.

Non-Normal Operations
This section describes pilot techniques associated with engine inoperative
approaches. Techniques discussed minimize workload, improve crew
coordination, and enhance flight safety. However, a thorough review of applicable
Non-Normal Checklists associated with engine inoperative flight is a prerequisite
to understanding this section.
One Engine Inoperative
AFDS management and associated procedures are the same as for the normal ILS
approach. Flight director (manual) or autopilot and/or autothrottle may be used.
Weather minima for an ILS with one engine inoperative are specified in the
applicable AFM and/or the operator’s Operational Specification or equivalent.
777-200 - 777-300ER
During a multiple autopilot approach with the TAC inoperative, the pilot must use
rudder pedal pressure to control yaw, followed by rudder trim to maintain an
in-trim condition until LAND 2 or LAND 3 annunciates. When LAND 2 or
LAND 3 annunciates, rudder inputs are controlled by the autopilots. Directional
control (yaw) is not affected by rudder trim with the autopilot in the LOC or
ROLLOUT modes.
787-8
During a multiple autopilot approach, the flight control system automatically
applies rudder inputs to controls yaw, followed by rudder trim to maintain an
in-trim condition until LAND 2 or LAND 3 annunciates. When LAND 2 or
LAND 3 annunciates, rudder inputs are controlled by the autopilots. Directional
control (yaw) is not affected by rudder trim with the autopilot in the LOC or
ROLLOUT modes.
777-200 - 777-300ER
Flying an ILS approach with the TAC operating is the same as flying the approach
with the TAC inoperative except that before LAND 2 or LAND 3 is annunciated,
rudder control is automatically accomplished by the TAC. When LAND 2 or
LAND 3 annunciates, rudder inputs are controlled by the autopilots.

Refer to the Performance Inflight chapter of the QRH to determine if a flaps 30
landing is permissible. Intercept the localizer with flaps 5 at flaps 5 speed. When
the glide slope is alive, lower the landing gear and extend flaps to 20. If a flaps 20
landing will be made, set final approach speed and decelerate. If a flaps 30 landing
will be made, at glide slope capture, select landing flaps, set final approach speed,
and decelerate.
