FCT 777/787 Preliminary (TM) 3.31
Roll Modes
After takeoff and climb is stabilized, select LNAV (if not armed before takeoff)
after passing 400 feet AGL. If LNAV is armed for takeoff, it engages above 50 feet
AGL and within 2.5 NM of the active leg. If the departure procedure or route does
not begin at the end of the runway, it may be necessary to use the HDG SEL mode
at 400 feet AGL to intercept the desired track for LNAV capture. When the
departure procedure is not a part of the active flight plan, use HDG SEL, TRK SEL
or HDG HOLD mode. When an immediate turn after takeoff is necessary, the
desired heading may be preset before takeoff.
777-200 - 777-300ER
Navaids and appropriate radials or tracks required for use during the departure
may be displayed on the navigation display using the FIX page feature and/or
VOR/ADF switches on the EFIS control panel. Use of the STA and WPT switches
on the EFIS control panel provides additional information on the navigation
display.
787-8
Navaids and appropriate radials or tracks required for use during the departure
may be displayed on the ND using the FIX page feature. ADF is also displayed on
the mini map when the station is tuned on the CDU. The VOR station is displayed
when selected on the ND menu.
Pitch Modes
Normally, VNAV is armed for takeoff and engages at 400 feet AGL. The use of
VNAV for takeoff, flap retraction and climb out is the preferred method of
managing the AFDS for takeoff. This provides the VNAV profile and acceleration
schedule compatible with the planned departure.
Autopilot Engagement
The autopilot is FAA certified to allow engagement at or above 200 feet AGL after
takeoff. Other regulations or airline operating directives may specify a higher
minimum altitude. The airplane should be in trim, and the flight director
commands should be satisfied before autopilot engagement. This prevents
unwanted changes from the desired flight path during autopilot engagement.
Flap Retraction Schedule
During training flights, 1,000 feet AFE is normally used as the acceleration height
to initiate thrust reduction and flap retraction. For noise abatement considerations
during line operations, thrust reduction typically occurs at approximately 1,500
feet AFE and acceleration typically occurs between 1,500 and 3,000 feet AFE, or
as specified by individual airport noise abatement procedures.

3.32 FCT 777/787 Preliminary (TM)
VNAV, armed on the ground with the appropriate acceleration altitude entered, is
the recommended technique for acceleration.
With VNAV engaged, an acceleration is automatically commanded. Retract flaps
on schedule. Check that the thrust reference changes from TO to CLB on the
EICAS at the point selected on the TAKEOFF REF page.
If VNAV is not used, at acceleration height select FLCH and set the command
speed to flaps up maneuvering speed. Check that the thrust reference changes
from TO to CLB on the EICAS. If the thrust reference does not change
automatically, set climb thrust using the CLB/CON switch on the MCP.
With airspeed increasing, subsequent flap retractions should be initiated:
• when airspeed reaches the maneuvering speed (number) for the existing
flap position.
For flaps up maneuvering, maintain at least:
• “UP”
Note: The maneuver speed provides margin to stick shaker for at least an
inadvertent 15° overshoot beyond the normal 25° angle of bank.

Note: Speeds depicted in the table are approximations of the speeds displayed on
the airspeed display and are intended for use only as a back-up.
Noise Abatement Takeoff
Normal takeoff procedures satisfy typical noise abatement requirements. Thrust
reduction and acceleration heights should be entered on the TAKEOFF REF page
of the FMC. Maintain flaps up maneuvering speed until the noise abatement
profile is satisfied, until clear of obstacles or above any minimum crossing
altitude. This is normally achieved through the FMC speed restriction entered on
the CLB page. It may also be accomplished using speed intervention or FLCH.
Note: Specific local airport procedures should be followed.
