If an engine fails between V1 and liftoff, maintain directional control by smoothly
applying rudder proportionate with thrust decay.
During a normal all engine takeoff, a smooth continuous rotation toward 15° of
pitch is initiated at VR. With an engine inoperative, a smooth continuous rotation
is also initiated at VR; however, the target pitch attitude is 12° to 13°, or
approximately 2° to 3° below the normal all engine pitch attitude. The rate of
rotation with an engine inoperative is also slightly slower (1/2° per second less)
than that for a normal takeoff. After liftoff adjust pitch attitude to maintain the
desired speed.
If the engine failure occurs at or after liftoff apply rudder and aileron to control
heading and keep the wings level. In flight, correct rudder input approximately
centers the control wheel. To center the control wheel, rudder is required in the
direction that the control wheel is displaced. This approximates a minimum drag
configuration.
Liftoff Pitch Attitude - One Engine Inoperative
Liftoff attitude depicted in the following tables should be achieved in
approximately 5 seconds. Adjust pitch attitude, as required, to maintain desired
airspeed of V2 to V2+15.

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/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: Limit bank angle to 15° until V2 + 15 knots. Bank angles up to 30° are
permitted at V2 + 15 knots with takeoff flaps.
After completing the turn, and at or above flap retraction altitude, accelerate and
retract flaps.
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.
