Note: The maneuver speed provides margin to stick shaker for at least an inadvertent 15° overshoot beyond the normal 25° angle of bank.
After flaps and slats retraction is complete, select VNAV or set the desired climb speed in the MCP speed window. Before selecting VNAV, flaps should be retracted because VNAV does not provide overspeed protection for the leading edge devices.

Noise Abatement Takeoff
Normal takeoff procedures satisfy typical noise abatement requirements. 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 be also be accomplished using speed intervention (as installed) or LVL CHG.
Note: Specific local airport procedures should be followed.

PMC Off Takeoff 737-300 - 737-500
When takeoff is performed with the PMCs off or inoperative, engine RPM increases as speed increases during takeoff. At high airport elevations the RPM increase may approach 7 percent. The takeoff performance charts for PMC Off reflect the RPM increase.

Takeoff - Engine Failure General
Differences between normal and engine out profiles are few. One engine out controllability is excellent during takeoff roll and after liftoff. Minimum control speed in the air is below VR and VREF.
Engine Failure Recognition
An engine failure at or after V1 initially affects yaw much like a crosswind effect. Vibration and noise from the affected engine may be apparent and the onset of the yaw may be rapid.
The airplane heading is the best indicator of the correct rudder pedal input. To counter the thrust asymmetry due to an engine failure, stop the yaw with rudder. Flying with lateral control wheel displacement or with excessive aileron trim causes spoilers to be raised.
Rotation and Liftoff - One Engine Inoperative
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 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.
Typical Rotation - One Engine Inoperative
Liftoff attitude depicted in the following tables should be achieved in approximately 5 seconds. Adjust pitch attitude, as needed, to maintain desired airspeed of V2 to V2+20 knots.
