If full thrust is desired when THR HLD mode is displayed, the thrust levers must be manually advanced. When making a V1(MCG)-limited takeoff, do not exceed the fixed derate thrust limit except in an emergency.
After the airplane is in the air, pushing a TO/GA switch advances the thrust to maximum available thrust and TO/GA is annunciated.
Initiating Takeoff Roll Using HUD System 737-600 - 737-900
Normal procedures apply, however, pilots must be aware that the captain’s attention is devoted almost exclusively to outside/HUD cues. This requires that the first officer’s attention be devoted to head down instruments more than during the normal takeoff roll.
The captain monitors the takeoff roll by using visual cues and HUD symbology. Use HUD guidance symbology, runway lighting and runway markings to maintain runway centerline. Rotate using the airplane reference symbol on the HUD.

Rotation and Liftoff - All Engines
Takeoff speeds are established based on minimum control speed, stall speed, and tail clearance margins. Shorter bodied airplanes are normally governed by stall speed margin while longer bodied airplanes are normally limited by tail clearance margin. When a smooth continuous rotation is initiated at VR, tail clearance margin is assured because computed takeoff speeds depicted in the QRH, airport analysis, or FMC, are developed to provide adequate tail clearance.
Above 80 knots, relax the forward control column pressure to the neutral position. For optimum takeoff and initial climb performance, initiate a smooth continuous rotation at VR toward 15° of pitch attitude. The use of stabilizer trim during rotation is not recommended. After liftoff use the flight director as the primary pitch reference cross checking indicated airspeed and other flight instruments.
Note:  Do not adjust takeoff speeds or rotation rates to compensate for increased body length.
With a consistent rotation technique, where the pilot uses approximately equal control forces and similar visual cues, the resultant rotation rate differs slightly depending upon airplane body length.
Using the technique above, liftoff attitude is achieved in approximately 3 to 4 seconds. Resultant rotation rates vary from 2 to 3 degrees/second with rates being lowest on longer airplanes.
Note:  The flight director pitch command is not used for rotation.

Typical Takeoff Tail Clearance
The following diagram and table show the effect of flap position on liftoff pitch attitude and minimum tail clearance during takeoff. Additionally, the last column shows the pitch attitude for tail contact with wheels on the runway and landing gear struts extended. For a discussion of tail strike procedures see chapter 8 and the FCOM.
737-300 - 737-500 Note: Use of flaps 1 as a takeoff flap setting is restricted to airplanes delivered with this capability or to airplanes having flaps 1 installed as a takeoff flap setting.
Tail clearance height

737-300 - 737-500
Model  Flaps  Liftoff Attitude (degrees)  Minimum Tail Clearance inches (cm)  Tail Strike Pitch Attitude (degrees) 
737-300  1  10.0  23 (58) 
5  9.9  24 (61)  13.4 
15  8.1  37 (94)

15  8.1  47 (119) 

Note:  Flaps 1 (-300) and flaps 5 (-400) takeoffs have the least clearance. Consider using a larger flap setting for takeoffs at light gross weights. Because of the short fuselage, aft fuselage contact is unlikely in the 737-500.
