Initial Climb - All Engines
After liftoff, use the attitude indicator as the primary pitch reference. The flight
director, in conjunction with indicated airspeed and other flight instruments is
used to maintain the proper vertical flight path. Pitch, airspeed, and airspeed
trends must be cross-checked whether the flight director is used or not.
After liftoff, the flight director commands pitch to maintain an airspeed of V2 +
15 to 25 knots until another pitch mode is engaged.
V2 + 15 is the optimum climb speed with takeoff flaps. It results in the maximum
altitude gain in the shortest distance from takeoff. Acceleration to higher speeds
reduces the altitude gain. If airspeed exceeds V2 + 15 during the initial climb, stop
the acceleration but do not attempt to reduce airspeed to V2 + 15. Any speed
between V2 + 15 and V2 + 25 knots results in approximately the same takeoff
profile. Crosscheck indicated airspeed for proper initial climb speed.
Retract the landing gear after a positive rate of climb is indicated on the altimeter.
Do not apply brakes after becoming airborne. Braking is automatically applied
when the landing gear lever is placed in the UP position. After gear and flaps are
retracted, the PM should verify that the gear and flap indications are normal.
Minimum Fuel Operation - Takeoff
The minimum fuel recommended for takeoff is trip fuel plus reserves. On very
short flights this fuel quantity may not be enough to prevent forward fuel pump
low pressure lights from illuminating after takeoff.
If any main tank fuel pump indicates low pressure do not turn off fuel pump
switches. Avoid rapid acceleration of the airplane, reduce nose-up body attitude
and maintain minimum nose-up body angle required for a safe climb gradient.
Immediate Turn after Takeoff - All Engines
Obstacle clearance, noise abatement, or departure procedures may require an
immediate turn after takeoff. Initiate the turn at the appropriate altitude (normally
at least 400 feet AGL) and maintain V2 + 15 to V2 + 25 with takeoff flaps.
Note: A maximum bank angle of 30° is permitted at V2 + 15 knots with takeoff
flaps.
After completing the turn, and at or above flap retraction altitude, accelerate and
retract flaps while climbing.
Note: The possibility of an engine failure along the departure track must be
considered. Special engine out procedures, if available, are preferable to a
takeoff weight reduction to ensure all obstacles are cleared.
