Takeoff and Initial Climb

3.36 FCT 777/787 Preliminary (TM)
Initial Climb - One Engine Inoperative
The initial climb attitude should be adjusted to maintain a minimum of V2 and a
positive climb. After liftoff the flight director provides proper pitch guidance.
Cross check indicated airspeed, vertical speed and other flight instruments. The
flight director commands a minimum of V2, or the existing speed up to a
maximum of V2 + 15.
If the flight director is not used, indicated airspeed and attitude become the
primary pitch references.
Retract the landing gear after a positive rate of climb is indicated on the altimeter.
The initial climb attitude should be adjusted to maintain a minimum of V2. If an
engine fails at an airspeed between V2 and V2 + 15, climb at the airspeed at which
the failure occurred. If engine failure occurs above V2 + 15, increase pitch to
reduce airspeed to V2 + 15 and maintain until flap retraction altitude.
The flight director roll mode commands ground track after liftoff until LNAV
engagement or another roll mode is selected. If ground track is not consistent with
desired flight path, use HDG SEL/TRK SEL/LNAV to achieve the desired track.
Indications of an engine fire, impending engine breakup or approaching or
exceeding engine limits, should be dealt with as soon as possible. Accomplish the
appropriate recall checklist items as soon as the airplane is under control, the gear
has been retracted and a safe altitude (typically 400 feet AGL or above) has been
attained. Accomplish the reference checklist items after the flaps have been
retracted and conditions permit.
If an engine failure has occurred during initial climb, accomplish the appropriate
checklist after the flaps have been retracted and conditions permit.
Immediate Turn after Takeoff - One Engine Inoperative
Obstacle clearance or departure procedures may require a special engine out
departure procedure. If an immediate turn is required, initiate the turn at the
appropriate altitude (normally at least 400 feet AGL). Maintain V2 to V2 + 15
with takeoff flaps while maneuvering.
Note: The AFDS limits the bank angle to 15° until V2 + 10 knots to maintain at
least adequate maneuver margin. The bank angle limit increases to 25° by
V2 + 20 knots if LNAV is engaged, or when HDG SEL or TRK SEL is
engaged with the bank limit in AUTO.
After completing the turn, and at or above flap retraction altitude, accelerate and
retract flaps.

Autopilot Engagement - One Engine Inoperative
777-200 - 777-300ER
When at a safe altitude above 200 feet AGL with correct rudder pedal input as
needed, the autopilot may be engaged. If the TAC is not operating, rudder trim
must be manually applied.
787-8
When at a safe altitude above 200 feet AGL with correct rudder pedal input as
needed, the autopilot may be engaged.
Flap Retraction - One Engine Inoperative
The minimum altitude for flap retraction with an engine inoperative is 400 feet
AGL. During training, flap retraction is initiated at 1,000 feet AGL.
At engine out acceleration height, if VNAV is engaged, a near-level climb
segment is commanded for acceleration. Retract flaps on the flap-speed schedule.
With flaps up and airspeed greater than VREF 30 + 78 knots, VNAV automatically
sets the reference thrust limit to Max Continuous Thrust (CON).
At engine out acceleration height, if VNAV is not engaged, select flaps up
maneuvering speed on the MCP. Engine-out acceleration and climb capability for
flap retraction are functions of airplane thrust to weight ratio. The flight director
commands a near level flap retraction segment. Accelerate and retract flaps on the
